The protection circuit has operated, this is not uncommon on microwaves. the fuse is inside the unit and therefore require dismantling. replace fuse and all should be fine, if it blows again then you have a more serious problems

The kitchen timer button does not work on my Kenmore circular wave microwave.


If it has membrane switches, you might have a bad switch. Or, you could have a bad connection between the touch panel and the circuit board. Or the circuit board itself could have a problem.

Your membrane keypad has failed.

On this model, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly (controller assembly, sub) which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

It is part number 4781W1A299D and you can get it for $55.44 plus shipping from Encompass here or you can call them toll-free at 866-779-5835.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.

Microwave PLMVZ169 GCB night light push button does not work. Replace the light bulb. Push button still does not work. The work light does when I push the night light it stays on. Just wondering how to...


Q - While trying to change the light bulb on the oven, the bulb broke. When it did, it threw the circuit breaker and the whole oven went out. After resetting the breaker, everything on the oven works except there is no power to either light socket. Any ideas or suggestions on what to replace?
A - You tried to change the light bulbs with the power still on.....tsk tsk!!
Hate to say this....but probably blew out part of the circuit on the smart board ( the brains behind the key panel you touch ) when the short blew. The light relay on the smart board may have been damaged but 9 out of 10 times when I check them, the board itself is damaged.
check out this problem.
please do rate the solution.thank you for using fixya.keep updated.thanks,

Microwave went dead


Hi

If your microwave oven doesn't seem to work at all, check these: Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.


Please do rate the solution as FixYa and revert for further assistance.

Thanks

Hi cschnur,
     It seems that you might need to replace circuit board.
All the above mentioned conditions refers to a faulty circuit board. You might have blown few Ic's.
Take a voltmeter, check the continuity. If you are aware of the Ic's, replace them.
Unless, look for a tech, a used board ( On http;//www.ebay.com ) or purchase a new one.

Thanks for using Fixya.

One of two thing happened here...
1. most likely...One of the interlock switches has malfunctioned. Micro. will NOT opperate unless ALL switches are working properly for safety
2. possible...the start button on the touch pad has failed in the circuit.
