Our microwave oven acts like it is working - all

Hi, you have a faulty magnetron, capacitor, or diode that's keeping the unit from heating anything. They have internal fuses, but its good or nothing wood work. You can have these parts checked out at a appliance repair store, but wit parts and labor it may cost more then a new one just to be truthful with you. If you are handy, you can get into the electrical section and may get luck and see which part is faulty just by looking at them, for any blackish, scorching on any circuit boards, a capacitor is a small round or oval shaped part that holds a charge and these sometimes will leak, swell up and crack causing them to fail. If you want, you can try this. If you do have a board, this is where any diodes would be on the face of it, remove it enough to look on the back side for scorching and you can take it and purchase a new one and be back on line. These are just some options you may want to try. It may be something like a capacitor that is very easy to change out. This may save you some $$$$.If this is an older model, you may want to look for another, but if its a newer, I would spend the time to do the things I have said. I wish you the best on this, and want you to save your $$$$ on this. Please keep me posted, and would you please rate me on any help I may have been to you? Thank you!

I just asked a question about a microwave: does

From your description it sounds like a bad magnetron especially if is loud laboring to run, the high voltage transformer is been loaded down by the magnetron and that is where the noise is coming from. There are two other parts that should be checked, the high voltage diode "opens/shorts" and the high voltage capacitor sometimes become defective.

The time and the light still comes on but it does

Sorry to read about your problem, I hope this helps you out.

You may have a defective, keypad issue, or even a defective defective control board.

Careless troubleshooting of a microwave oven can result in death or worse. Experienced technicians have met their maker as a result of a momentary lapse of judgement while testing an oven with the cover removed. Microwave ovens are without a doubt, the most deadly type of consumer electronic equipment in wide spread use.

The power supplies for even the smallest microwave ovens operate at extremely lethal voltage and current levels. Do not attempt to troubleshoot, repair, or modify such equipment without understanding and following ALL of the relevant safety guidelines for high voltage and/or line connected electrical and electronic systems.

Microwave oven has a code of F-3 can not start


F3 is an error indication that there is a short in the key pad assembly. It is likely that this assembly will need to be replaced.

Be aware that Microwaves carry potentially lethal levels of voltage even when completely unplugged from the mains supply.

For this reason I recommend you get a tech to look at your microwave and you do not attempt any repair to a microwave yourself.

It is likely that the keypad assay will need to be replaced. This part costs usually around $100. You will also have a labour cost also to consider so you should weigh this cost up in economic terms before you decide to proceed.

Hope this helps. Please do rate this answer. Thanks.

Oven error -f3-

In most cases that code means you have a shorting keypad.

If you could post the full model number, I'd be happy to point you to the best source in case you or a friend want to replace it yourself.

Otherwise, we regularly repair these for customers nationwide for $39.95 postpaid plus thew cost of the keypad.

Details of our service and critical safety information and disassembly information is at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

Microwave will not turn off

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

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be 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. Other times, 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 probably find exploded views and order parts by entering your model number here at the Sears parts site.

There may 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 think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

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

Kenmore Microwave model Fan running and light on when door closed.

This is normal. Kenmore microwaves will stay running with fan and light on for a short time after food is cooked. The reason is to air out the microwave after cooking. Things like pop corn, Bacon etc. have strong smells after cooking. The ventilation helps to remove odors.
