Does the fan still work?
It could well be the magnetron that has gone if your food is not heating up. You can test them using a ohms meter.

yea , the fan works fine, weird tho that a panasonic microwave has a LG magnetron

btw would any OHM meter work or has it have to be specific ??

you want a low resistance one, so it can take low readings.

please be extremely careful with microwaves mate they are the most dangerous item you will ever encounter in a domestic or arguably a commercial property! capacitors may hold about 2500V (5000V if operational) if not discharged and this will carry a hefty current enough to kill to the point no resuscitation will help - all relative to earth if still plugged in too

Also I would suggest a tired magnetron could still show a normal resistance.. - only the heating coil has a resistance the rest is like a tuned aerial.

u scared me enough not to play with it i contacted some ppl who fix microwaves but the cost would exceed the value of it so i guess i =m just gonna buy a new one
