My spacemaker model number jvm1850bhow just stopped heating food. What do I do?
This is a microwave, correct?
I suspect the door lock interface switch(es) are burned out. Unplug it, be mindful of the 25,000 volts in the silver thing. Check the micro switches (look where the door closes on the top right side, probably) two positions, normally open or normally closed. check them for proper operation.
Micro switches are the most common of microwave failures because most of us open the door while the machine is running causing arc at the switch and burning up the little contacts.
