Question about Microwave Ovens

2 Answers

I have a built-in GE microwave Model JTP85W0A1WW built in April 1999. It appears to work (fan turns on and digital readout counts down) but the turntable no longer turns and nothing is heated. Seems strange that both of those would go wrong at the same time. Any thoughts ? Hugh Patrick hdpatrick@yahoo.com

I had the exact same problem. There are two switches on the door. One is a safety lockout switch for the magnatron. The switch just wears out.

Strange the turntable should be on the same relay as the fan but,.

It could be that the same relay that runs the turntable is running the mag tube and its bad.

It has to be turoble shot voltages checked on the turntable motor and heat transformer primary. to find out whats wrong.

GE Model # JVM7195SFSS microwave.


Check the internal ceramic fuse on the circuit board. Sometimes one section will work while another won't. I'm not sure if this model has a rear mounted thermal fuse, but the models with the inline thermal fuse will cause a similar issue.

GE Spacemaker XL - fan stopped working, light will come on and timer will count down.


either the magnatron fried , or the fuse fried... either way the microwve has to be taken down and opened up.
If you have the serial number , GE will send you a replacement magnatron (but will not service the unit for you).
contact GE and they will take care of you... the magnatrons are warranted for like 10 years....

I suggest you have the microwave oven replaced, the prices have dropped considerably for the last several years and you have got your money worth out of the unit.

Light, fan and timer work but microwave does not


Microwaves are pretty much a non repair item. It will cost you more to fix than it would to replace.

JVM1190 wont cook


You have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.
