Bart July 18, 2025 for Model Number SCB1000MBB01 Suspecting the humidity sensor has failed b/c any cooking that provides an increase in humidity within the unit causes the digitron display to become erratic and eventually go black. After airing out the unit and power-cycling the unit I am able to eventually restore full function. Would like to know where the sensor is located and whether the Pwr Ctl Board is still in the mix of suspected failure. BTW, the GE unit is firmly installed as a built in and I will be unable to "pull it" despite having removed the 4 screws in the front. Thinking about the rear wall which is in a closet. Pushing the unit may be my only means of removing it once I open up that wall. My approach would be to apply pressure at the bottom and sides intermittently until the unit is freed. Any reason NOT to do that?
1 Answer Hello Bart, thank you for contacting AppliancePartsPros.comThe humidity sensor WB27X10857 is located on the left side of the microwave towards the rear and requires the unit to be uninstalled and the outer cover removed.The display's erratic behavior and eventual failure may not be related to the humidity sensor itself. If you can access the boards behind the control panel I would first check for loose connections, wires not fully seated in their connectors, and corrosion, as this sounds like poor connectivity or possible moisture intrusion as the unit heats up and humidity increases. To remove the control panel the unit will need to be at least partially uninstalled.With the 4 screws in front removed from the side trims, the microwave should slide/pull forward with 2 people grasping the front and rear of the unit underneath on each side. If the unit is not coming out of the install location it will need to be determined what is holding it in place. Read More...
David August 22, 2023 for Model Number mlmv2031bd unit will over cook potatoes or over heat on sensor reheat. Is this the sensor?
1 Answer Hello David, yes most likely it is the Humidity Senior 6501W1A013A that is failing, the control board uses it to determine the level of heating needed in sensor cooking. Read More...
James April 06, 2019 for Model Number LMVH1711ST F5 code error which everyone says is humidity sensor. If I order the part is there somewhere I can get instructions on how to replace it.
1 Answer James, first you would need to remove your microwave from the wall and place it on a cloth. From there, you will need to remove the grille and outer cover of the microwave. This will give you access the the sensor 6501W1A013A which can be located at the back left of the unit when looking at it from the front. Read More...
Cocenar September 07, 2018 for Model Number JEB186CSN1SS My GE microwave oven is not heating although everything else works. All the interlocks are good. There is 120Vac on the primary of the HV transformer. The HV diode and the capacitor is also good. There is a 0.1-ohm resistance between the terminals of the magnetron and no continuity between the ground. There is no evidence that the HV transformer is bad. What else could be the problem?
1 Answer Hello Cocenar, If all components are good and there is 120Vac to the primary side of the high voltage transformer, the unit should run and heat. The only thing I can think of that you didn't mention is the magnetron thermostat WB24X10163. Read More...
Kathy February 19, 2018 for Model Number lmv1813SB When I start the microwave, the panel shows it is working but there is no power to the microwave. The lights work and the fan works. Is there a door sensor or something that might be broken?
1 Answer Hello Kathy. You will need to test all the door switches on the unit. Thank you. Read More...
Modnart December 15, 2016 for Model Number lg lmh2016st The vent exhaust fan does not go on after a flare up on stove. Can I replace a part to fix this?
1 Answer Modnart, There is a thermostat in the top of the microwave that may have failed. You will want to check for continuity on this thermostat and make sure that it has continuity. If it does not then the part is defective and will need to be replaced. Read More...
Carl August 15, 2015 for Model Number lmhm2017 Do I need to pull the microwave cover to replace the cook sensor on this model # imhm2017sw?

Jd September 14, 2014 for Model Number LMV1925SB Microwave starts off seemingly working fine, after approx. 1 1/2 min. the unit stops heating and turning. Timer continues, lights work etc. Unit will not start heating again until unit rests for 5 to 10 min (as if its overheating inside somewhere). Upon a clicking noise and then re-programing the unit to cook again, the unit will restart again, only to stop again, can continue to repeat the process over and over.
1 Answer Hello JD. Check the circulation fan motor 6549W1F001W and see if it is bad. If so, it will cause the unit to over heat. 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...
Danny February 10, 2014 for Model Number Kenmore 721.81043 My Microwave is 3 years old I just started having problems with the buttons when pressing start or the 5 button the microwave would do nothing. So I unplugged the microwave for a couple minutes plugged it back in then it would work then I would go to use the microwave then I would have same issue with the buttons not working. What could cause this problem?
1 Answer Hello Danny. It sounds like the control panel is bad and will need to be replaced on the unit. Read More...
Albert L. October 26, 2013 for Model Number lmv1813st LG My lg microwave is still giving an error code of F-4 after I replaced the 6501w1a013a sensor. Only sensor cook is affected. What else could be causing the error code. I did check the resistance in my old sensor, R-B = 6.44K, R-W = 3.213k, W-B = 3.2k, W-B = 3.21k. Thank you.
1 Answer Hello Albert, If changing the sensor did not correct the issue, you may have to replace the control board EBR64419603. Since it is the part interpreting the information sent to it, it could have an issue with the circuit that reads the information sent to it. Read More...
