1 Answer Ernie643, No there is no shrink wrap that comes with the diode and is not required for it. Read More...
George December 29, 2015 for Model Number JVM1450AA001 Wondering what the part no. on diode and magnetron are for this model. Are they available?
1 Answer Hello George. You need to order WB27X10597 and WB27X10735 for the model number provided. Read More...
Bo December 06, 2015 for Model Number HVM1540LN1CS GE microwave does not heat up. Everything else works. I am thinking it is the HV diode or capacitor. The capacitor is vertical and would make it very hard to short out. Can I remove one wire at a time making sure not touch anything with needle noise then unplug the diode remove the capacitor from the bracket then short it with needle noise so I can test every thing with my dc meter, Thanks: BO 12/26/15
1 Answer Hello Bo. It is best to discharge the capacitor. Use a long screwdriver and pliers if needed to do so. 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 transformer should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. All of these are +- 10%. If all the readings are proper and in range, replace the magnetron. Read More...
Joe November 29, 2015 for Model Number JTP86S0H6SS Can you help me troubleshooting my Microwave ( GE Oven and Microwave build-in ) makes loud noise and bad smell inside and does not heat up food. What part(s) do I need? and what is the parts N and, and is the way to test the magnetron. Thank you.

Tim April 24, 2015 for Model Number ZET3038SH3SS Our trivection oven is 7 years old. We have had different control problems over the last couple of years. But now the oven bakes alright elements are working, but when put into speed cook the microwave does not seem to be functioning. The unit seems to make a louder humming sound over the fan noise than it used too. But now takes longer on speed bake than it does to just use it as a regular oven. Everything on these sites points to the diode? Is it also possibly the transformer? The unit is a wall mount so not very easy to access for testing or repair. What are your thoughts? A lot of these blogs generalize these questions and the unit they are talking about is something totally different than what we have. I realize the way it works is the same, but I would just like to be on the same page involving this unit. Thank you, Tim
1 Answer Tim, While the diode could be causing the issue, normally it will stop heating all together. Although a diode that is failing could cause the issue. The transformer could also be weak and causing the unit to not heat properly if it is failing. Read More...

Rob F October 26, 2014 for Model Number GE Microwave JVM6172DF1WW Purchased it new 3 weeks ago. It tested OK then. Now it's power is very low. The power level says it's 10. But when I put 1 cup of room temperature water in & run it for 1 minute, the water temperature only reaches 130 degrees, I believe it should have been about 212 degrees. What do you think the problem is? Thank you, Rob
Mary C June 17, 2014 for Model Number JNM1541SN1SS My microwave does not heat anything up anymore. It has a burning smell. Everything else is in tact. What could this problem be? Could it be the diode? Please give me the best advise. Thanks.
1 Answer Mary, The odor that you are smelling would most likely be caused by a faulty diode. The diode would need to be replaced. Read More...
1 Answer Hello Marty. You need to check the fuse in the noise filter board WB27X11160. If it is bad, you will need to replace the fuse and test the door switches. They are the number 1 cause of the fuses blowing. Read More...
