You need a microwave fuse. Also the reason for it blowing fuses may be that it's time to replace the capacitor inside. It may be time for a new magnetron too. If you have the top open look to wires that burned in two and may be touching the frame If that is so you may not need any parts at all. Also check the thermal cutoffs (button looking safety equipment)

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

SOURCE: Microwave Oven Does Not Start Cooking

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

If yours is not shown at the parts site or manual site linked above, Please reply back with your brand and model number so we can help you.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: My fan nor lights work on my Frigidaire microwave PLMV168KC4

Assuming you're talking about the hood vent exhaust fan and the cooktop lights, my solution is below. If not, please write back with details.


We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week.


At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

I have a PLMV178HC Frigidaire microwave oven. The oven has stopped heating things up completely, but it still turns on and the tray still turns when I try to heat things up. What could be wrong and ca


Most microwaves have an internal fuse; it might be blown. To access it, you'd have to take the oven apart (usually just a few screws), BUT capacitors inside could store hundreds of volts, even after the unit has been unplugged for a while, so do not attempt to replace it unless you are familiar with HV circuits.
Other possibilities are a burnt-out magnetron or tranformer; it would be cheaper to buy a new oven than to replace those components.

Microwaves and how they work.

Caption
--> ­T­he microwave oven is one of the great inventions of the 20th century -- millions of homes in America have one. Just think about how many times you use a microwave every day:


Caption
-->
­

­You're running late for work, so there's no time to fix breakfast at home. On your way to the office, you stop to gas up your car. Inside the quickie-mart, you grab a frozen breakfast burrito and pop it in the microwave on the counter. Later that day, you have to work through lunch. By 3:00 p.m., you're starving, so you grab a snack-pa­ck of microwaveable popcorn from the vending machine and pop that in the break-room microwave. That night, after a really long day at work, you're simply too tired to grill out, so you dish up last night's lasagna and heat it up in the microwave...
As you can see, microwave ovens are popular because they cook food in an amazingly short amount of time. They are also extremely efficient in their use of electricity because a microwave oven heats only the food -- and nothing else. In this article, we'll discuss the mystery behind the magic of "meals in a minute" with microwave cooking.

­A m­icrowave oven uses microwaves to heat food. Microwaves are radio waves. In the case of microwave ovens, the commonly used radio wave frequency is roughly 2,500 megahertz (2.5 gigahertz). Radio waves in this frequency range have an interesting property: they are absorbed by water, fats and sugars. When they are absorbed they are converted directly into atomic motion -- heat. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics. Metal reflects microwaves, which is why metal pans do not work well in a microwave oven.

Microwave cooking ­You often hear that microwave ovens cook food "From the inside out." What does that mean? Here's an explanation to help make sense of microwave cooking.
Let's say you want to bake a cake in a conventional oven. Normally you would bake a cake at 350 degrees F or so, but let's say you accidentally set the oven at 600 degrees instead of 350. What is going to happen is that the outside of the cake will burn before the inside even gets warm. In a conventional oven, the heat has to migrate (by conduction) from the outside of the food toward the middle. You also have dry, hot air on the outside of the food evaporating moisture. So the outside can be crispy and brown (for example, bread forms a crust) while the inside is moist.

In microwave cooking, the radio waves penetrate the food and excite water and fat molecules pretty much evenly throughout the food. No heat has to migrate toward the interior by conduction. There is heat everywhere all at once because the molecules are all excited together. There are limits, of course. Radio waves penetrate unevenly in thick pieces of food (they don't make it all the way to the middle), and there are also "hot spots" caused by wave interference, but you get the idea. The whole heating process is different because you are "exciting atoms" rather than "conducting heat."
In a microwave oven, the air in the oven is at room temperature, so there is no way to form a crust. That is why microwavable pastries sometimes come with a little sleeve made out of foil and cardboard. You put the food in the sleeve and then microwave it. The sleeve reacts to microwave energy by becoming very hot. This exterior heat lets the crust become crispy as it would in a conventional oven.

Frigidaire model PLMV178HC control panel replacement


I can't find if there's a difference between model PLMV178HC and PLMV178HCA. Every search for PLMV178HC redirects me to PLMV178HCA. Unless there is grease or moisture on the control circuit board, then you have a shorting membrane keypad.
It is repaired by replacing the control panel frame assembly, which comes with a new membrane keypad already attached.

For model PLMV178HCA, that is part number 5304470533 and you can get it from Sears online for $89.95 (subject to change).

At my Web site, I have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes. (Also, the service manual is here.)

If you have any trouble getting the grille off once the screws are removed, slide the hood vent grille to the left about 1/4", then then pull it forward. On some models there are L-shaped clips that fit into a slot to hold bottom of the vent.

Be very careful when disconnecting the cables & wires. Some connectors have a locking tab (see photo) Next remove the keypad strip (see photo) Then simply move your circuit board into the new frame.

Be careful, because your display tube is made of glass, and if it breaks, the board must be replaced as well.

Let me know by e-mail if I can help further.
