Ge dual wave ii microwave system

[helpneeded]

Hey Everyone!

I have a GE Dual Wave II Microwave System. It is an in wall microwave and oven unit. The problems that I've been having have just been going on for about 2 days. The first day the microwave the microwave seemed normal( normal sound, light, timer) but no heat.... after trying 2 to 3 times it would heat up and then die again. The second day after trying to heat an item it worked but the problem was i placed a cup of water in the microwave and hit 2 seconds and the water was scalding hot. Then i left the door closed and the a strange fan sound started by itself ... so i opened the door the lights came on the inside walls were hot. Something kinda smelled like it was burning...so i switched it off and took off the screws and disconnected all the cables in the back of the unit.

Please let me know if you have any ideas. I know the unit is old but its an expensive thing to replace.... Would it be better to replace it or try and repair it. I really really appreciate your help.
Thanks

GE Dual Wave II Microwave System

That is not enough information to identify the appliance in question. What is needed is its exact model number.

after trying 2 to 3 times it would heat up and then die again.

That might be caused by a thermal protector opening up due to overheating of one of the internal components. It might also be caused by an actual failure of one of the cooking components or maybe even the electronic control board failing.

i placed a cup of water in the microwave and hit 2 seconds and the water was scalding hot.

In two seconds?!?

Then i left the door closed and the a strange fan sound started by itself

That could just be the cooling fan. It could be triggered by a thermostat sensing an overheat condition or by the control board (depending on the microwave's actual design) for some reason.

the inside walls were hot.

There is no heat source inside a microwave besides maybe the light bulb or heat from an item being heated/cooked. Was the light staying on?

Another slim possibility for a heat source is a failure of the magnetron tun or HV transformer but I wouldn't expect such a condition to affect the temperature of the oven cavity much, if at all.


I usually don't recommend homeowners try to repair microwave ovens them self. I suggest you call a factory service agent to look into it for you.
