Panasonic Microwave – turntable and light not working…

[brightspark]

Hi all,
I have a Panasonic combination microwave model NN-CT579S. After a brief power cut during a lightning storm, the turntable and the interior light no longer work.
The microwave still heats as it should, as long as you turn more solid stuff and stir bigger quantities of liquids every now and again.
I’ve replaced both the bulb (which looked well burnt out) and the turntable motor but not much joy. The new bulb does not work (but tests for continuity OK), and the turntable does work, but only when the door is opened. While not a total novice with power circuits, I’m wary of testing components with the cover off, what with the potential for big shocks and self cooking. Before I spend any more time, is it still worth trying to repair ?
It’s only a couple of years old.

if you remove the pcb you will find a blown track on the board. if you repair the track and if the relay that controls the lamp or turntable has not fused it will be ok

You can still get a big shock even if the oven is unplugged.

So if you are working on it make sure you discharge the HV capacitor first.
