Unit turns on, turntable turns, but nothing heats


Classic symptoms for failed door interlock safety switches, though it could be other trouble.

Remove the cover and check the operation of the little micro switches that operate when you close the door.

DONT TOUCH THE SILVER CAN - LETHAL.

If you regularly open the door while cooking, the contacts in these little switches become burned. When burned badly enough, they cannot make contact. When they cannot make contact, the mocrowave doesnt know the door is closed and will not turn on the magnatron resulting in no heat.

If you need more help, let me know.

Micro blow circuit


You have a faulty interlock switch. This is one of two or three switches in every microwave that are operated by the door. The interlock switch is wired to blow the fuse if you try to run the oven with the door open. The switch may have gotten knocked out of adjustment (say by slamming the oven door) or its contacts stuck closed. If there are no other problems with the oven, a new switch should clear this up.

LG micro oven it not heat


I am not an expert on Miocrowave ovens, but from past experience I know that they have a number of micro-switches on the door as safety devices. If these switches are faulty, the last safety feature is to short the supply and blow the fuse to stop the microwave from operating in an unsafe condition. Obviously the switches would have to be checked first before jumping to any conclusions and a number of other faults would probably cause the fuse to blow as well.
