Dale March 13, 2014 for Model Number jv1750dm1bb Tracking down the diode on my microwave. (no heat) Off the capacitor to ground? Only thing that looked like a diode. Multimeter tested both ways, open. Cut back the shrink wrap and it was oily on the inside. Did I find the diode?
1 Answer Hello Dale. Here is a picture of the diode to see what it looks like WB27X10597. It is attached to the capacitor and then to the cabinet. Read More...
Lal October 25, 2013 for Model Number JVM1850M2SS I installed the parts WB27X10597, WB27X10880, & WB27X10166 in our Microwave (JVM1850M2SS). The microwave worked for one day and then failed as before. It was used only to make one Mac/Cheese for a child. I did the repair at my son's place in San Jose on 10/12/13 and had to return back to LA. Any help resolving this issue will be appreciated. Thanks
1 Answer Lal, The most likely cause for the unit to stop operating after replacing the thermostat, diode, and magnetron would be a faulty HV transformer on the unit. Read More...
Brian October 18, 2013 for Model Number JT930S0K3SS GE wall oven Model JT930S0K3SS hasn't been used for a couple days. Yesterday morning clock was working by evening, clock was dead, keyboard is dead, even light inside oven won't come on with open door. No power outage or surges, breakers are all intact. Any thoughts? Thank you in advance.
1 Answer Hello Brian. You need to uninstall the unit and check the wiring on the unit and make sure the proper voltage is there. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Cb September 23, 2013 for Model Number hvm1750sm1ss I have power to outlet. The microwave has no power totally dead.
1 Answer Hello CB. You need to test the fuse and see if it is bad and will need to be replaced on the unit. You can test this with a multi-meter TJMA-DMT3.

Earl June 24, 2013 for Model Number Ge profile spacemaker 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 or the magnetron? Please give me the best advise,thanks.
1 Answer Earl, In most cases when there is a burning odor then the diode has failed and would need to be replaced. Read More...
Wayne June 24, 2013 for Model Number JVM1870BF06 I have a spacemaker xl1800. Everything works but no heat come thru. I bought a tester, snd need to know correct method of testing the capacitor, and the Diode-H.v Ass'y to see which one i need. How should I proceed? Do I take the part off and test them, or test them live?
1 Answer Hello Wayne. Do not test them live. You will remove the diode from the unit. It should only read in one direction. If it reads both ways, it is bad. As for the capacitor, it has the readings on the tag and you will need a tester to test those. You can test this with a multi-meter TJMA-DMT3.

Ty April 11, 2013 When I turn on my GE Profile Spacemaker XL1400 it does not heat at all. The screen displays a sensor error after a few minutes of running and cuts off. What could be the problem?
1 Answer Hello Ty, This is most likely either a shorted or open humidity sensor. There are over 25 model numbers of the GE Profile Spacemaker Microwave line, so I cannot provide a part number with out the model number. There is too large of a chance that the part number will not be correct. This information must be correct to keep the unit operating safely in your home. If you could please either re-post with the model number or call us at 1-877-477-7278, we will be more than happy to locate the part number you require for your model number. The model number will be on the units' I.D. tag around the door of the unit. Read More...
Flashpointmo March 13, 2013 for Model Number Tappan My Tappan over the range microwave that I had for 18 years, makes a loud humming noise and does not heat anything up. Could it be a diode?
1 Answer Hello flashpointmo. You need to check the magnetron and diode in the unit. Look for cracked magnets and make sure the magnetron reads less then 1 ohm. Also, the diode should only read 1 direction. You can test this with a multi-meter TJMA-DMT3.

Lou J. February 22, 2013 for Model Number PEM31SM3SS Hello, Not too long ago I noticed that there was a burning smell coming from my microwave. We tend to only use it for short periods of time (30 seconds to 2 minutes) and we noticed it was taking less and less time for the smell to be obvious. I looked around and found some discussions that implied that the rectifier was the most likely culprit. I ordered one and replaced it with the new one, but while things were open, I did test both rectifiers with a meter and a battery and saw that they both tested the same way. That was an indication that perhaps the old rectifier was not bad, but I left the new one installed anyway. While things were open, I searched for the source of the burning smell and it was clearly one of the connectors on the transformer wires that was burning and melting. I ensured both connectors were seated properly when I re-assembled the microwave, and when I began using the microwave there was no smell at all! I felt very smart and thought all was great, but then about a week later, the smell is back within just a few seconds. So, clearly the rectifier was not the problem. I'd like to assume it was the transformer, but could there be something else that is causing these items to overheat or the transformer to malfunction? Please help, my coffee is too cold to drink! Lou
1 Answer Hello Lou. It sounds like you will need to replace the transformer and replace the terminals on the wires that are burnt in the unit as well. Read More...
Bill Ory February 17, 2013 for Model Number PT970BM1BB My 4.5 year old GE Microwave PT970M1BB Buzzes Loudly when the door is shut. This microwave is built-in with an Oven below. Loud buzzing starts immediately when the door is shut. So far, I have replaced the Transformer, Magenetron & a plastic "Air-Cover" (basically a duct that goes between the Magenetron & the side wall of the microwave cooking chamber). I have also replaced a Diode that goes between the capacitor and the sheet metal of the microwave. The original "Air Cover" was melted on top so I assumed the Magnetron was overheating causing this problem. I just completed the replacement of all these parts and when I shut the door the buzzing starts and I see some "whisps" of smoke coming up from the magenetron. I am not sure if this is just because it is new and needs to break in a little and burn off some paint or if this is another symptom of the real problem. I called one of the sales folks and they looked up my problem and said that other Posts have indicated either a bad door switch or the control board for the microwave. Hopefully this will be a relatively cheap-fix since I have already sunk alot of money and time into this unit. Thanks for your help. Bill
1 Answer Hello Bill, It sounds like you have a bad control board or a shorted or pinched wire and will need to inspect the wiring. Read More...
