Where is the fuse located?
Answer Hello Deena. It is located in the control panel section of the unit. You must remove the outer cover off the microwave to access and replace the fuse in the unit.
Isn't heating food. Everything else is working. Light, Clock, turntable, timer, touch pad are all working. It just isn't heating the food. What part do I need to order?
Answer Hello Rita. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron.
My JVM 1431 WA GE Microwave Works fine except for the 2 40 Watt lamps in the bottom of the unit. I have replaced the bulbs.
Could it be the PS 242167 Fuse? If so , how do I access that fuse on my microwave? Thanks.
With the microwave working the fuses would not have anything to do with the cooktop lamps not working. The lamps route through the control board and if the control board is not sending power then the board would need to be replaced.
