Unfortunately, there is no way to tell which part the microwave needs without opening it up for examination. There are a few parts that, if defective, would prevent the oven from heating.

  • a high voltage transformer which passes energy to the magnetron
  • a magnetron which converts high-voltage electric energy to microwave radiation
  • a magnetron control circuit (usually with a microcontroller)
This is NOT a repair that you would want to attempt yourself. The labor for the repair would cost a minimum of $50 and shouldn't exceed $100. You'll also have to pay for the necessary part if it's still available from the manufacture or their parts distributor.

My microwave stopped working one day. A few times before it completely stopped working, the magnetron would pulse and then shut off. Now the only time it does that is when nothing is in the microwave. If...


If this is an older oven, or an oven that has heated a lot of popcorn, or other low water content foods, then you might be looking at a magnetron that has become intermittent. The symptoms you describe, however, do not match the symptoms you usually see with this type of failure.

Based on your description of the problem, I'd investigate the possibility of an intermittent power relay. The contacts on these eventually burn and sometimes don't make a good connection. After the contacts first close, there're is an initial surge of current that might make the relay functional for a second or two, and then the damaged contacts no longer make contact.

We just hooked up the hood fan and was wondering if it was normal that when you run the microwave the hood fan cuts in?


I do believe that is the normal way to get rid of the heat and any moisture while the micro is operating .

Code, F-9


This is not usually a consumer repairable fault - but you may be able to clear it simply by unplugging from the outlet for a minute or two and plugging it back in again. Try it out and if it works, you're all set - otherwise it might need to be seen by a pro.

Good luck!

Microhood blowing house fuse


normally it should blow the units internal fuse first if its an internal issue, first check the line cord thoroughly for any bare wires at the case , then remove outer case asn see if cord is bare anywhere inside, then inspect unit fuse, take a multimeter and take a resistance check in an upper range og the meter of the disconnected h.v. diode, then disconnect h.v. capacitor(DISCHARGE) across terminals before touching and check this part, then lastly it could be the magnetron tube, or the hi voltage transformer, therse are VERY expensive items,you may vie to replace microwave then

Microhood combo magnetron failure


If this is an over the range microwave that vents outside rather than recirculates the air back into the kitchen, make sure the magnetron cooling section of the blower was realigned to direst air downward over the magnetron. If the unit has a seperate internal cooling fan, make sure it is functioning. These checks need to be made by a qualified service technician only.
If it's a counter top unit, just make sure the internal cooling fan is functioning.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

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

Door switches are most often damaged by opening the door while it's cooking (instead of pressing Stop / Clear first) or food
/ grease debris in the switch.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya: http://tinyurl.com/yzjozk

It's also possible there may be a problem on the circuit board, which we repair nationwide.

Turnaround glass tray problem


Sometimes they get heated up and bend up in the middle so they don't make good contact with the coupler. The way I fix this is to heat the support over a stove flame, then place a heavy weight on it so it holds the legs up in place a bit until it cools. Here it is step by step: 1. Apply heat at points where each legs meet the hub (stove flame) 2. Place end of each leg on an object so that the bottom of the hub is held up about 1/8" off the work surface. 3. Place heavy object on hub so the bottom touches the work surface. 4. Let it cool. 5. Test it. 6. If it still does not work, increase the height of objects in step two.

Kenmore microhood


"Microhood" seems to be a slang term for the "microwave hood" (hood fan or exhaust fan) which is normally part of an over-the-range microwave oven or range. But these should be available separately, as I seem to recall. I would contact home centers such as Lowe's, Home Depot (if they still exist), etc., or a local appliance store.
