Mike November 23, 2012 for Model Number HVM1540SN2SS Hi, I have a 3yr old GE over the counter microwave oven, model # HVM1540SN2SS. Up until now I've had no problems with this oven, however, now when we put something inside everything works except, there's NO heat. All the controls work, fan, panel, and lights but no heat. What causes this problem and can I fix it myself?
1 Answer Hello Mike, Based on the information provided it sounds like your magnetron has failed and need to replace the magnetron WB27X10939. Read More...
Allan August 05, 2011 for Model Number JVM1740SM1SS Hi, This microwave (13 1/2 months old) does not heat the food. Everything works fine: the keypad functions are all there, the fan comes on, the turntable rotates, the light works, timer is ok, etc. It was OK when we left on vacation; did not work when we got home (have had a lot of thunderstorm activity). Is there a way to test the magnatron? Or are there other more likely causes? (Have unplugged it to attempt a reset-no diffeerence.) Thanks for your help! Allan
1 Answer Hi Allen. Does the magnetron growel when in action? The magnetron is tested with an ohm meter set on the highest scale. Reading across the terminals, you should read 0 ohms (or .5 ohms). Test both terminals to ground with one lead and make sure it is not shorted. This part Is part #WB27X10939. Also test the diode. Ohm meter on Rx1 scale, you should read continuity one way,and none the other way (reversing the leads). This part # is WB27X10597. Thank you. Read More...
