That is not enough information to identify the appliance in question. What is needed is its exact model number.GE Dual Wave II Microwave System
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.after trying 2 to 3 times it would heat up and then die again.
In two seconds?!?i placed a cup of water in the microwave and hit 2 seconds and the water was scalding hot.
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.Then i left the door closed and the a strange fan sound started by itself
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?the inside walls were hot.
Another slim possibility for a heat source is a failure of the magnetron tube 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.
