If your Emerson microwave is turning on and counting down but not actually cooking or heating the food, there could be a few potential causes for this issue. Here are some steps you can take to troubleshoot the problem:

1. Check Power Levels: Make sure the microwave's power level is set to the desired level for cooking. Some microwaves have adjustable power settings, and if it's set too low, it may appear that the microwave is running but not cooking properly.
2. Door Interlock Switches: Microwaves are equipped with safety interlock switches that prevent the microwave from operating when the door is open. If any of these switches are malfunctioning or not engaging properly, it could prevent the microwave from cooking. Ensure that the door is fully closed and the switches are working as intended.
3. Turntable and Support: If your microwave has a turntable, make sure it's properly seated on its support and able to rotate freely. If the turntable is not turning, it could result in uneven cooking or no cooking at all.
4. Magnetron Malfunction: The magnetron is the component responsible for generating microwave energy for cooking. If the magnetron is faulty or not functioning properly, the microwave may appear to operate but won't actually heat the food. A malfunctioning magnetron usually requires professional repair or replacement.
5. High Voltage Diode or Capacitor: The high voltage diode and capacitor work together to convert the high voltage output from the transformer into microwave energy. If either of these components is defective, it can prevent the microwave from cooking. Again, professional repair may be necessary.
6. Control Board or Circuitry Issues: A malfunctioning control board or other electronic components could also lead to a situation where the microwave appears to operate normally but doesn't actually cook. If you suspect control board issues, it's best to contact a professional technician.
7. User Manual: Double-check the user manual for any specific instructions or troubleshooting steps related to cooking issues. The manual may provide guidance on common problems and their solutions.

If you've checked these common issues and the microwave still isn't cooking, it's advisable to stop using it and contact Emerson customer support or a professional appliance technician for further diagnosis and repair. Microwaves contain high-voltage components that can be dangerous to work with, so it's important to prioritize safety and seek professional assistance if needed.

here are some items to check for troubled microwave Bad Magnetron Symptoms What are some bad magnetron symptoms to watch out for? The following is a brief list of some of the most common signs that your magnetron is about to give out: Heating: Either the microwave is not heating up at all, or the heating performance has degraded noticeably. Burning Smell: A burning smell (non-food related), may be an indication that elements of your magnetron are overheating. In this case, switch off your microwave immediately, and arrange for a repair or replacement. Unusual Noises: All microwaves make a bit of a hum, but if it's become much louder - or sounds like unusual vibrations - your magnetron may need to be replaced. Watch out for a clicking sound as well - that's a tell-tale sign of a magnetron that's about to fail.

Is It Worth Replacing The Magnetron In A Microwave?

It really depends on the cost and age of your microwave. If it's somewhere between five and seven years old, you're in the right period of time for a replacement anyway. There's little point spending good money on repairing or replacing a magnetron if the rest of the appliance is likely to give up the ghost soon anyway! Symptoms of a Bad Microwave Diode? (Answered!) A microwave diode is one of the most important components in the appliance. Without it, it's impossible to generate the heat required to heat foods and drinks placed in the oven cavity. Unfortunately, the component can go bad, so it's important to understand the symptoms of a bad microwave diode. Generally, the symptoms of a bad microwave diode include sparking, buzzing and humming, and the appliance failing to heat. Running a continuity test helps to determine whether the diode has a problem. Getting a new diode for replacement is the solution if the current one fail the continuity test. 3 Symptoms of a Bad Microwave Diode The following table shows the summary of the symptoms of a bad microwave diode as well as what you can do to fix the problem: Symptoms Solutions 1. Microwave buzzing and humming Inspect the diode, test it for electrical continuity, and replace it if it fails the continuity test. 2. Microwave not heating Start by inspecting the capacitor and magnetron because they may also be responsible for making the microwave fail to heat. 3. Microwave is sparking Locate the diode, inspect it, and test it for continuity. Replace it if there's no continuity. There aren't too many symptoms of a bad microwave diode. The most common ones include sparks & burning smells, the microwave not heating, and the microwave making humming & buzzing.

1. Microwave Starts to Have Heating Failures

Apart from a failed main control board, a faulty fuse cavity, a blown line or thermal fuse, and a faulty door switch, the high-voltage diode could also be the possible reason why the Whirlpool, Kenmore, GE, or KitchenAid microwave is not heating. Your microwave failing to heat is a perfect sign of a faulty diode, which means you should get a new one for replacement.

2. The Microwave Starts to Pop Sparks

Sparks in your Kenmore, LG, Samsung, or Whirlpool microwave could be a sign that the high-voltage diode is defective. Also, a burning smell from your microwave can indicate that the diode is bad. A burned-out diode can break into two, wear out, or short. Immediately locate the diode in the cabinet next to the magnetron and replace it.

3. Microwave Starts to Make Noise

Your microwave could be buzzing and humming because the high-voltage diode is defective. Apart from the diode, other components that can make your microwave make noise are the plate & drive motor, cooling fan, and magnetron. Keep in mind that you can't repair a bad diode. You can only replace it with a new one.

Safety Warning

While repairing a microwave, the chances of falling into electrocution by the high-voltage capacitor even after unplugging the power cord from the socket are very high. So you need to be very careful when doing the diode test. To begin with, the high-voltage diode is located close to the high-voltage capacitor. In fact, one of its ends is attached to the high-voltage capacitor. And as you know, a microwave capacitor carries high power voltages, which can be quite lethal. It is therefore important to start by discharging the capacitor before getting to the high-voltage diode. Although the capacitor can store charge for a long time, touching both its negative and positive terminals with a metal screwdriver blade will drain all the charge in seconds.

Testing the Microwave Diode

Before you even attempt to replace the diode on your GE, Whirlpool, or KitchenAid microwave, do a functionality test to confirm your suspicion. You can visibly confirm the diode is burned-out when you see physical damages. In case there are physical damages, use a multimeter to test if the diode still has a continuous electrical path. To test the diode for continuity: Touch the positive and negative terminals of the high-voltage diode with the multimeter probes. If the diode test negative for continuity on both of its sides, the diode has failed and will need a new one for replacement. Microwave maiking loud noises

Tip #3: Weird Noises

. A high-pitched noise while the microwave is in use means there's a good chance the magnetron tube or diode is failing. If the exhaust fan or magnetron tube are the culprits, you will need to call a local appliance repair service. DIODE HIGH VOLTAGE You might have an issue with the high-voltage diode if your microwave is generating an odd or loud whirring sound. This element, together with the magnetron and the capacitor, is a part of the high-voltage circuit. The cabinet needs to be taken out in order to get to the diode. BUZZING AND HUMMING Most buzzing or humming noises are frequently caused by the fan motor, vent fan, magnetron, or any combination of these. This noise from routine operations gradually gets louder over time. As the microwave oven warms up, the oscillation happens, and the fan helps keep the mechanical parts from overheating. You might need repairs if the volume of your microwave suddenly increases. Try running the magnetron at a lower power setting while putting food inside to see whether the magnetron is the cause of your problem. This will cause the magnetron to switch on and off to maintain the proper temperature. If the magnetron is the issue, there should be less noise. CLICKING NOISES Even though your microwave might not have a revolving plate, some models spin food using a glass turntable or plate. This component aids in ensuring even heating throughout your meal. However, occasionally clicking noises may result from this action. If you constantly hear clicking, see if your glass plate, roller ring, or track needs to be cleaned. These are simple to clean with soap and water, but you might have neglected to do so. The location of the plate is what determines the other option, so be sure it is still on course. POPPING As you prepare food or after spilling food, you might describe the sound of your microwave as popping, crackling, or snapping. However, these tones frequently come from dishes with significant water or fat content, particularly sauces. POWERFUL SOUNDS When it comes to microwaves or other appliances, these noises continue to be the most alarming. You should replace your microwave if the device starts to make an electric-sounding noise called arcing.

If you notice that while using your microwave, the electricity flashes in addition to making a sound.

Stop using your microwave if this occurs and you notice a hole in the back o WHY DOES MY MICROWAVE MAKE A VIBRATING NOISE

There can be various reasons behind a microwave making vibrating noises. Some are given below. POWER MOTOR Your microwave's drive motor may be malfunctioning if the turntable is making an odd noise. The majority of microwaves with glass trays turn the tray with a motor-driven coupler or a roller guide. Access must be made through the bottom of the oven because the motor is normally found below the floor. Normally, a holding screw holds the motor in place, and two wires are connected to it as well. The motor must be replaced if it is creating a grinding sound. its because it is now dangerous. A loud humming or buzzing sound could result from a damaged magnetron PUSH COUPLER If your microwave is making an odd noise, the drive coupler for the turning tray can be the cause. The majority of microwaves with spherical glass trays revolve around the tray on a roller guide using a motor-driven coupler. A drive coupler with an offset center roller is sometimes used in models that employ a rectangular tray to move the tray guide from side to side. Remove the tray and roller guide from the oven for either style and then check the coupler. Before you can pull the coupler off the motor on some models, you might first need to remove the motor from the bottom. ROLLER GUIDE If the turning tray in your microwave makes an odd noise while rotating, there might be an issue with the roller guide underneath the tray. A motor-driven coupler is sometimes used in microwave ovens with spherical glass trays to turn the roller guide.

Symptoms of a Bad Door Switch If you are experiencing any of the below symptoms, there is a good chance you have a bad microwave door switch:

• Your microwave doesn't start up when you close the door and press the start button
• Your microwave's interior light, turntable, or fan turns on automatically when you open the door without you hitting the start button
• Your microwave pauses randomly in the middle of cooking as if you had opened the door when the door is still tightly shut

To be completely safe, you should discharge the capacitor before you go poking around inside your microwave. The capacitor is usually located at the bottom right corner of the microwave. . How to Test For a Faulty Microwave Door Switch The first thing you should do to test the micro switches is by opening and closing the door. You will want to first rule out the possibility the latch or hook is broken and not activating the switch. Watch to make sure the latch activates the plunger on the top of each switch as you open and close the door. When the door opens and closes, the plunger should depress and pop back up. For my microwave, I noticed the plunger on one of the switches stayed down when the door was opened and closed. This was the bad switch. If all the door switches and latches appear to be working correctly visually, the next step is to test that they are working correctly internally. You will see two or three terminals on the switch. The terminal on the bottom of the switch will usually be the common (COM) and the ones on the side will be a normally closed (NC) or a normally open (NO) terminal. If you don't know which terminal is which, there will be a diagram on one side of the switch. Look for which marking the terminal is located next to. Remove the wires connected to the terminals. Using a multimeter set for continuity, touch one probe to the COM terminal. Now if you touch the other probe to the NO terminal, it should read no continuity because that circuit is normally open. Now press down on the plunger. You might sometimes hear a 'click' and your multimeter should report there is continuity. Testing the NC terminal is similar to testing the NO terminal. Keep one probe on the COM terminal and touch the other to the NC terminal. You should have continuity when the plunger is up because the circuit is normally closed. When you depress the plunger, the circuit should open and your multimeter will say there is no continuity. Replacing the Faulty Micro Switch Once you have found the bad switch, remove it from the door panel. The switches will usually be mounted on pins through the holes at the corner of the switch with brackets holding it in place. Should you have trouble getting access to or removing the switches, they are usually all mounted on a plastic frame with screws securing it to the microwave. Remove the screws and you should be able to pull out the frame with all the switches at once. Once you get the microwave door switch out, you could open it up and try to fix it if you are super cheap, but it will likely fail again soon after. A better long-term solution is to replace it since they are so inexpensive. These switches are usually rated up to 100,000 operations electrically and 10,000,000 operations mechanically. To find a replacement switch, look on your old switch for the voltage rating and the type of switch you need. It might have one terminal that is normally open (NO) or normally closed (NC). It could also have both NO and NC terminals, known as a Single Pole Double Throw or SPDT switch. My microwave had two NO switches and one NC switch. My switch was rated for 15A - 1/2HP - 125/250 VAC, 0.6A 125 VDC or 0.3A 250 VDC. You can order a normally open micro switch or a normally closed micro switch on Amazon for about $5 with the above rating. You can also order a SPDT micro switch with both the NO and NC terminals and only use one of the two terminals.lastly check for bad control board

There are no official wiring diagrams because there is supposed to be no home repair. That capacitor has about 120,00 volts at 10 amps just waiting for you to get within an inch of it.

Thanks for the info about the lifetime warranty, who knew? The two parts mentioned are flow control valves that get inserted at the base of the sprayhead, not the in the hose. The green one says "water care" which will restrict flow more than the white one. It's an either or scenario, not both. There is a VERY faint arrow that points up toward the top of the nozzle. Push it all the way up and reconnect the hose tightly. That's it. My replacement didn't come with a wrench, did that come with the original faucet? One more thing, if you bought a house that has this and don't qualify for the lifetime warranty, don't get stuck paying $100-$150 for this part if you just need to replace the aerator. The gray head that the water comes out twists out with a wrench revealing the aerator. The part number is 13929 or sometimes referred as 1392900, $10-15, if you can find it.

The black marks are burnt debris caused by splashing inside the oven. (Cling film usually stops this). The waveguide cover, refered to as mica, has nothing to do with the actions of the magnetron, it is there to stop particles of food from entering the waveguide.

Lift up on bottom of microwave door while pushing in on door release.

Wine coolers can stop cooling for six common reasons - A break in electricity, compressor problems, capacitor problems, the condenser fan stops working, a defective thermostat, or a broken evaporator. Most of these problems can be troubleshot at home, but a technician is needed for advanced issues.

Now there's a question. I would read the instruction manual that comes with all microwave ovens.

Consumer fuses are normally on the rear where the power lead goes in. It is a small screw cap or a long pull out fuse with a small notch in the end. If there is an internal fuse, it will be on the main circuit board. Getting inside is normally not easy because of security screws. https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..
