A different kind of microwave problem
This is a fairly old Panasonic microwave.
It does all the usual things that it is asked to. It heats. The timer times. The turntable rotates. It seems to have developed a mind of its own. Occasionally, after it is through heating and shuts off it does something strange. When the door is opened, the interior light comes on again and the turntable starts turning. During this time it is not trying to heat. The off button does not affect this action. Close the door and the light goes out and the turntable stops. After a bit it reverts back to normal and stays truly off as expected. Is this phenomenon governed by the control electronics, which would probably call for a replacement microwave or is it caused be the failure or misadjustment of one or more of the mechanical switches that could be remedied by a DIYer?

Charlie Hi, You know that there is two interlock switches on the door latch.(one at the top and one at the bottom). Those two switch works in certain sequence. When they don't, oven does weird things. |

Sounds like an output device on the control board has become flakey. There are no adjustments involved. |
