Eric Alexander for Model Number JMC8130DDB My 2007 microwave stopped heating. I checked my microwave for all the usual issues: magnetron, door latches, capacitor and determined that the problem was my diode. When I checked it, according to the testing meter, it appeared to not allow the current to flow in either direction. I checked the part I needed and bought the replacement diode. Samsung Diode, part # AP4236698 (DE91-70063D) (It looks just like the old diode). The brand new diode does not appear to allow the current to flow in either direction based on meter testing. I had a another old diode which showed that the meter was working properly and showed that the current could only flow in one way. Are microwave diodes different than standard diodes? Did I buy a deficient part, or is the problem with the microwave something else entirely? Thanks
Answer Eric, A microwave diode would be the same as other diodes but would suggest installing the new diode to see if this will correct the heating issue. Read More... Answered by AppliancePartsPros.com | Thursday, November 9, 2017
