A different microwave problem
This is a fairly old Panasonic microwave.
It does all the usual things that it is asked to do. 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 I would check all the door switches, relays, look for cracked solder joints or bad electrolytic capacitors on the control board. It's probably something you can fix. |

forgot to mention in previous post, have you taken the cover off
and looked inside for a schematic? (there was one inside my old GE mw oven) if you find one, look at what controls the turntable. |

I may be a flakey door interlock switch. I have one that does something similar, though I've never gotten around to actually figuring out what's going on. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.

Charlie No door switches should affect the turntable. The problem must be flakey control electronics. |
