The problem was a "secondary switch" in the door.
it got hot at some time and it made the plastic body of the microswitch melt or soften.
over time the micoswitch contact inside the switch made intermitant contact, until i kept trying to use it it went open cct.
when i took the control panel off ,i found the schematic and the basic troubleshooting guide rolled up under the keypad.
after reading other posts, safety tips etc. i found them helpful.
thanx to the admin for this forum................. :o ]]

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.

Sharp Carousel R530BK microwave won't cook unless light pressure is kept on the door button.


There are door switches and one of them is evidently out of adjustment or the little actuator arm on it is.

Microwave timer works but will motor will not run/cook.


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.

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.

JVM1190 wont cook


You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.

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
