If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

SOURCE: frigidaire won't run

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: fan works,light works,timer counts down when you

This is a problem associated with the magnetron. Either the power supply (transformer, diode, capacitor) or the magnetron itself. UNPLUG, remove cover, check for burn marks, a blown fuse, and test all components. Likely you have a bad magnetron (test for low resistance lead to lead, infinite either lead to ground). I found a new magnetron, removed from freight damaged oven, online for about $40. Mine is a built in which would cost $300+ to replace, so it was worth fixing. I hope this helps you.

Cook works microwave timer stuck

If by "manual timer" you are referring to a knob that you turn to set the cook time, then you may have a failure of the motor that turns the timing mechanism, or a lack of power to it.

Microwave jes1142

If the timer counts down and nothing else happens, the secondary interlock switch is bad. This switch completes the cook circuit and this is why it doesn't run. You need an ohm meter to diagnose and find the right switch. Switch failure is caused by opening the door when it is in cook mode. Push the stop button first before opening the door and this failure will cease to occur. BE CAREFUL !!

The timer counts down but the microwave doesnt turn on.

I have a FNCB115GC Microwave problem. The microwave has a icon on the left hand side of the panel that looks like a opened book on a stand with lines on top. This is best that I can descibe it. The microwave turntable does not move or the microwave does to come on but the light comes on and the timer will count down. I have cleared the microwave and unplugged it with no results. Please help. Thanks in advance.
