SOURCE: faulty microwave oven

So it's dead? (No lights, no beeps when you press a key?)

A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.

But - this model uses and inverter. Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

SOURCE: microwave oven not heating

Test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

The diodeand capacitors can be tested. The capacitor must bealloweddischargebefore testing, or you risk to get electrocuted, evenifpower is off.Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

How can I get my microwave to actually heat when everything else (cook time, power level, clock, etc., are set and seem to be running?


Sounds like the MW Emitter is not working or the wave guide is disconnected. If it is the wave guide then you can fix it yourself if you take the rear cover off. It is the pipe, which in cross section is quite rectangle shaped with rounded corners. It should be connected to the emitter at one end and the opaque guide cover at the other with no breaks. If the emitter is faulty then seek professional help.

My sisters has a Sharp microwave r-403hw was manufactured july 2003 my question is how long are you allowd to keep a microwave for and if the inside chips from the paint is still ok to cook food in it or...


As long as the microwave oven is working to heat or cook according to the program set , the micro wave can be used safely. Now if there is any chipping of the paint within the oven chamber, then you can re-coat the inside with non conducting ceramic paint.
However if there is no issue if there is no damage to the inside or to the working of the microwave as you can use the oven till it fails to heat.

My high power GE Advantium microwave is sparking


Your problem is a common one. When you see arcing inside your microwave, it's because of food or liquid left in the cavity or on the wave-guide cover:

  • If the wave guide has any burn spots, replace it and clean the unit well.

  • If the cavity has any burn spots, spot-sand it smooth and touch it up with microwave interior paint.
Note… If there are any burn holes in the cavity, don't use the unit-seek help from a qualified appliance repair technician.

Clicking When Unit Starts


Q - When there is small amounts of food in the oven, arcing occurs right behind the plate where the wave guide comes into the oven. Sometimes it works well and sometimes you can't even put in a bag of popcorn. Any ideas? Could food have 'dripped' in here and be causing a microwave short?
 
A - Yes! Food splatter or drips can continue to cook and will carbon over creating sparks/arcs from the wave guide cover. Usually can clean up the food on and under the wave guide cover, if the oven liner has been damaged we usually lightly sand and touch up those marks with touch paint. Do not let it go for too long as damage to the magnetron end is possible as well :(   If the wave guide cover has been damaged, replace it!

Kenmore 721.80524500 makes a buzzing, grinding noise


Your problem is due to the "magnetron" arcing to the wave guide within the microwave. Picture someone arc-welding stuff together inside the microwave casing, that's essentially what's happening. It is a fire hazard and you should stop using the microwave immediately. As far as I know, there isn't a recall on that particular model (though there was on another similar Kenmore/Whirlpool model) so if it's out of warranty, you're out of luck.

Emerson microwave oven model number MW8115SS


You don't state how old your oven is, or if you tried other food items afterwords. I also assume you inspected for foreign metal objects in the oven? If it does this whenever you attempt to cook in it, then it sounds as if your oven may have a wave guide cover malfunction or burned area.This part can be replaced by the consumer in most cases, but only after consulting with a trained technician or your parts supplier.
