Lg 700 w microwave everything is working as normal but the food is not heating up

If everything is normal, the magnetron is the likely issue "heats food" and is the heart of the system, I suggest having it checked.

if your microwave does everything you have described , and you can hear the cooling fan running as well after you press the start button , you probably have a faulty wave guide. The wave guide is also called a Magnetron Tube. It is the main part of the microwave which produces the microwave energy . If this part is not functioning it is best to replace the entire unit, rather than have it repaired .

magnetron faulty

Normally when u cook food in microwave the fod is cooked by microwaves, which means the heat is generated with in food. The temperature inside is never too hot and all the heat produced is absorbed with in the food.

On the other hand when the grill is switched on, a separate heatting element gets switched on. You can see this red hot element on the top side of inside of microwave. the heat from this element gets transferred to food through air circulation. But partof heat also gets transferred to the walls of microwave oven. This is the reason the wall feel hot during use of grill.

As i see ther is no problem with the microwave itself. Jut kep delicate thngs a bit away from the microwave.

If everything appears to work as normal but does not heat, then the magnetron will be faulty. This is the device which cooks the food, however this can be an expensive part to replace & may not be economical to fix.

I have a GE Spacemaker Microwave, model # JVM1650WB008

The lights work and everything runs in a normal operation, it will not heat the food. I have changed the fuse and still the same, no heat.

PROBLEM MAY BE A RELAY ON THE CONTROL BOARD OR MAY BE A LOOSE WIRE FROM THE HV TRANSFORMER CKT.
