Question about GE Spacemaker JVM1640SJ Microwave Oven
My first GE spacesaver just like this one lasted for 17 years. I
have had this one for 5 and it just stopped heating. It turns
onlike normal but nothing every heats up or defrosts. Any
GE Microwave ovens, and Microwave Ovens produced by GE but released under different brand names, have had several power problems for the past 20 years. Because it is so easy to sell parts and charge outrageous rates for repair GE never corrected the problems. They just continued it in the next model. They found that you would most likely purchase a new unit rather than paying $75. for a service charge, and $150. for labor plus parts (if out of warranty period).
Most failures were cold solder connections on the power relay board. These would come completely dis-connected after arcing and burning away the solder. Could be 1 month, could be years, but they knew it would happen. This power relay board feeds 120volts to the LV (low voltage) side of the HV (high voltage) Transformer. No High Voltage,,No cook. Everything seems to run normal, but if you listen carefully you will not hear the low tone from the HV Transformer. Over my thirty years in the business I have re-soldered rather than replace so many I couldn't count.
Next to that, a defective Magnetron.

Update: I ordered a magetron from someone with an ebay store for about $43 with shipping already included (was a part from a display model but with moneyback guarantee). I installed it and microwave works! Thanks, Totalwreck for saving me hundreds of dollars!
