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?

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.

before this problem, did the light normally stay off when door was opened? (my old GE microwave oven always turns the light "on" when the door is opened)

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.

Picky, Picky. Instead of picking directly on Sam, you should correct his spelling of flakey.

Gee, I thought he spelled it that way for the Europeans. ;-)

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