Svfair September 19, 2022 for Model Number JVM1790WK01 Good morning. We have a GE Profile JVM1790WK01 Microwave. About two weeks ago, it stopped working. The Primary Interlock Switch failed the Volt Meter Test. I replaced the Primary Interlock Switch and the Holder Locker. I did notice that the top wire within the connector to the primary switch had a burn mark. But the connector looked ok. The microwave worked for about two weeks. After that, very erratic behavior. Including total shutdown. Not flowing fuses. Typically, you can depress the CLOCK button to restore the display. Opening / closing the door would also cause the unit to fail / start to work. I tested all three switches. All OK. The top is N/O. Middle N/C and the bottom one is N/O. Alignment of the mounting (Holder Locker Part) which I also replaced when I replaced the switch appears good. I tested the switches while they were in the unit (Pulled control panel and the individual switch connectors). Last night I cut off the connector for the primary switch and replaced the connector for the upper connector (White + Red). I used a heavy gauge wire and soldered the wire to the White + Red Wires. For the first time in two weeks, the unit worked fine. All functions worked. Heated water for over 2 minutes, twice. Able to control the fan, light, turntable,etc. About 30 minutes later, the unit "blanked" out. No display, not able to activate Fan or light. Opening / closing the door has some impact. The keypad works erratically. I pulled the plug. I am wondering if the Main Control Board (WB27X10866) is to blame. I appreciate any / all assistance. Thanks Steve
1 Answer Svfair, Check the thermostats to make sure that they are not bad but if they are good then replace the control board. Read More...
Emarks March 09, 2022 for Model Number ZSA1201RSS I have a GE Advantium Microwave for 8 years now. When we do the 30Second quick button for the microwave the microwave operates but does not warm/cook. The turntable operates and lights go on, there just isn't any heating. Would anyone know a fix or recommendation for this?
1 Answer Emarks, It would be recommended to check the door switches on the unit to make sure that they are good. Also, check the capacitor, diode, and the magnetron to make sure that they are good. Read More...
Rodney January 21, 2022 for Model Number JVM1790BK01 Display no longer shows time, but does show cooking info. Pressing knob hardly ever works, but other buttons still do. Which board do I need to replace on this Microwave?
1 Answer Rodney, The part number needed for the control board on this model will be WB27X10866. Read More...
Mike November 21, 2020 for Model Number PVM1790DR1WW GE Microwave Mod# PVM1790DR1WW will pause randomly, mostly when I try to start heating something, but sometimes it pauses out of nowhere. The turntable stops whenever it pauses. Sometimes the turntable stops but microwave continues but it does not say pause on the screen. Looking to see if this might be the turntable motor or possibly the control board going bad? Hitting the cancel does not stop the microwave when paused but opening the door does. Any help would be greatly appreciated.
1 Answer Mike, with an intermittent failure, the issue would most likely be in the main control WB27X10866. The touchpad WB07X11342 ribbon can be tested for continuity from the ribbon position 5 to position 10. If there is only continuity when the start/pause button is pressed, the touchpad is good.

Jim September 12, 2020 for Model Number GE PVM9179sf1ss My GE convection over the range microwave keeps blowing the main fuse. If I put in a new fuse, the light work (both inside and out), along with the vent motor (all speeds), the control panel buttons, clock and all beeping noises. The problem occurs when I press start: the microwave starts for a have a second, makes a buzzing noise, and then everything goes dark (requiring me to replace the main fuse again. I tried to check all three door lock switches and the thermo fuses. From what I read on the internet it could be the main control board. Is there anyway to verify that this is the problem? Would hate to spend $150+ for the board and have the microwave still not work. Many thanks in advance for the helping hand.... Jim
1 Answer Jim, It sounds as if you have a shorted diode or magnetron. I would recommend isolating the high voltage by disconnecting a wire to the primary side of the high voltage transformer (tape it good before applying power to the unit) then see if the unit runs without blowing the fuse, if so then it is likely that either the diode, capacitor, or magnetron is shorted. If it blows the fuse then it is more likely to be a control issue. Read More...
Tom July 27, 2020 for Model Number GE Pvm1790sr1ss Intermittent heating. I completely disassembled and tested switches, cap, transformer, dialed, and magnetron. All good. Reassembled and it started working. Every couple of weeks , it stops. It will sometime work if I tap relays. I am stumped.
1 Answer Tom, Based on the information provided it sounds like you may need the board with the relay on it... WB27X10866 Read More...
Mary Singleton February 07, 2020 for Model Number JVM1790WK01 I ordered and received a replacement GE Microwave Main Control Board. Order # 629 0593 I was told it is quite easy to replace. There were no instructions in the shipping carton as to how to remove the current control board and replace it with the new board that was shipped to me. I could not find instructions on line for replacing my old board with the new board. Is there an instruction video online or printed instructions you could e-mail to me? Help! Thanks, Mary Singleton
1 Answer Mary, This will be an easy repair. You would need to remove the screws at the top of the unit that is holding the air grill at the top in place. Once these are removed you slide the air grill to one side and then remove it. Once the air grill is removed you will then remove a single screw that holds the control panel in place. Lift up on the control panel and remove the part. The control board will be attached to the control panel with screws. Mark the wires to where they go. Reinstall in reverse. Read More...
Paul December 15, 2018 We have a G E model JVM1790sk 01 Microwave aplliance. We cannot set the timer with the control knob. We can turn the time requested but when we push the round dial to set the timer or the correct time of day it doesnt set. Would this be the control board or not.
1 Answer Hello Paul, from the description it sounds like more than likely you will have to replace the board part number WB27X10866. Thanks! Read More...
Lonnie July 20, 2017 for Model Number jvm1790bk01 When I set the time to cook with the control knob and push it to start it doesn't start, but starts the countdown. If I push the time to cook it will start, but stops, but will start again when pushed again. The Convection oven will set and start, but never heats up to the preheat number. What part do I need to replace to fix this problem?
1 Answer Hello Lonnie. You will need to test the door switches and see if they are bad and will need to be replaced. 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...
Kris February 07, 2017 for Model Number PVM9179SF1SS My microwave convection ovens display quit working. Everything else seems to work so is this a control power board or possible something else?
1 Answer Hello Kris. It sounds like the control board is bad and will need to be replaced on the unit. Read More...
