Sounds like the turntable drive coupling is broken. In the bottom of the microwave where your turntable is, underneath that is a small drive coupling that the motor shaft pushes into. if the motor doesn't turn or the coupling, which commonly has a D shape shaft to keep it from slipping, is broken, the tray will not turn. One quick test it to remove your tray and see if you can turn the coupling easily by hand, if you can you probably have a broken drive coupling. The turntable motor is very difficult to turn by its shaft. so if it turns easily it is probably a broke coupling. NEVER force your turntable around by hand or you can break that coupling.
The electronics have lost their marbles. When a nuker door is opened the safety switch connected to the door is designed to turn the unit off and not on. You just better work fast when you put stuff in or take it out!!!!!!!
Unplug the oven and unfasten the cabinet body, using a screwdriver. The body should be attached along the back as well as along the sides or bottom.
Slide the cabinet body back slightly to clear any internal brackets, then lift it off.
Clean the oven, using a vacuum with plastic crevice attachment. Vacuum the fan and other internal parts, then vacuum the vents underneath the oven, on the back and inside the chamber.
Reassemble the oven and plug it in.
Fill a small bowl with a 50-50 mixture of water and white vinegar, then set it in the oven and turn the oven on high for 5 minutes. When the mixture boils, it will remove stubborn smells inside the vents and loosen food particles on the oven walls.
if there are not light there are usually two fuses in the unit one where the power cord comes into the unit and one that goes when the unit gets to hot. if the unit if a counter top unit you will need to go buy some safety star bits for the hardware store to get the cabinet off. just check the fuses with a ohm meter.
The fuse in most panasonics is under the exterior cover You undo the screws in the bottom of both sides and the top at the rear of the unit. Lift the surround up and away. This should then expose the inner works shell. On the left of the top you should see a fuse ( some are Ceramic block types of 30amp others are just heavy duty glass fuse types). If you replace that fuse all should be reinstated. Replace the outer cover and test.
Magnatron failure is rare. I suggest you check your door interlock safety switch. Do you regularly open the door while the machine is running? I did and I found out that the micro switches (door safety swwitch) are just not up to that kind of abuse. Your maching thinks the door is open because the contacts are burned to the point they do not close.
Unplug the machine, DO NOT TOUCH THE SILVER CAN! You will find the switches opposite the hinge. Check them with a volt ohm meter on contunity setting.
You cam probably get replacement switches at a electronics parts place.
There are other things that can be wrong but you should check these switches first. Cost should be less than $10.00 if you do it.
The turntable system
consists of the motor, the coupler, the turntable support with rollers,
and the tray.
You can see and hear a video of how a turntable motor should
sound when you rotate it by hand.
If
yours is not set to be off via the control panel, and it won't rotate
or it sounds like it's grinding, etc., you may have a bad motor or
plastic coupler.
To
replace either, you need to unplug power, then remove the bottom cover
of the oven.
You can order
parts for this brand from Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.
