Question about Jenn-Air JMC9158AA Convection Microwave Oven

1 Answer

Turntable won't stop

The microwave turntable keeps turning after the end of a cycle as long as the door is closed. Stops when door is opened, but starts to turn again as soon as the door is closed again.

    Same brand/type of microwave, except it's black (JMC9158AAB).

    Same problem, turntable spins when door is closed and light is on, without pressing any keys/buttons to tell it what you wanted it to do.

    Open the door and it stops spinning, but the light remains on. I have to trip the circuit breaker so it won't "sit" there in this mode with the door open and light still on.

    I have the same problem on a LG MC 806BL.  Any easy way of working out/replacing a blown relay or is a whole new control board needed?

    is usually caused by either a bad door switch, a loose door switch
    mount (which are pretty simple problems to fix) or occasionally a
    problem on the control panel such as a shorted relay.

    Have you recently had trouble with your cooktop lights?

    This failure often occurs when a bulb goes out and the filament
    shorts, or when the bulbs are removed or installed without first
    unplugging the oven from the power line. Either can cause such a
    failure on the controller.

    This can often also affect the exhaust fan operation, too. The lights and fan can be inoperable or stuck on too.

    Otherwise, you likely have a bad door switch or door switch mount.

    Please let me know and we'll take it from there.

Sounds like a door switch problem or stuck relay contacts on the control PCB. Do the light and fan run too or just the T/T??

Oven is off door closed and turntable is still turning in reverse

Most likely, one of the door switches has become non-functional.
Its usually the upper one. Test it with an ohm meter to make sure it makes contact in both positions.

Why does Panasonic nn-sn651 usually work; but sometimes, turntable won't start ?

This is an inverter model so there is no diode or hv capacitor.
You must adt. the door latch switch assembly to make sure that the door hooks make contact with the switches. Common problem is that the assembly is bent and must be perpendicular to the door.If it is bent the switch will not make contact with the door hooks.
Place a dab of lithium grease on the tip of the door hooks to ease closing the door. This is the cause of the bent switch assembly!

Microwave won't stop running

there's a ghost in your microwave, call ghost buster. Seriously, the problem is the control panel. (((((the microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. That's more than 30 wall outlets combined.
Replacing electronic parts in a microwave oven can be extremely dangerous.))))))) tank you

With the model number, we can offer more specific advice or an estimate.

But since FixYa does not notify us of follow-ups, you will need to post a new help request.
