Lonnie October 21, 2019 for Model Number Whirlpool Built in combo oven/ microwave WOC95EC0AS04 Microwave won't heat. One guy told me to replace magnetron and inverter board. Can I just replace the diode on the board and the magnetron? Do I have to take out the the bottom oven or can I take out the microwave only?
1 Answer Hello Lonnie, the wall oven/microwave would need to be uninstalled from its mounting for service. Removing the top panel then gives access to the mw components. The inverter is not considered repairable. The manufacturer does recommend if either the magnetron W11346197 or high voltage inverter board W10217711 is faulty both should be replaced. Read More...
1 Answer Mandel, To properly assist with your question we would need to have the model number of your unit. Please supply the model number and resubmit your question. Read More...
Mark June 29, 2018 Kitchen Aid KHHC2090SSS2. I get no heat at all. I have checked all of the common areas and all good. Could this be a control board issue? How do I put this unit in diagnostic mode?
1 Answer Hello Mark, I'm sorry but the model number you provided is for a refrigerator. If you are referring to a defrost issue where you get no heat you will need to pull the tech sheet and use the diagnostic mode to check the defrost circuit. Enter the Service Test Mode by performing the following sequence of events: 1. Press and hold the Door Alarm Keypad. 2. Press and hold Refrigerator Temperature UP / + Keypad. 3. Release the Door Alarm Keypad and wait 3 seconds. 4. The Freezer display will display SE confirming entry in the Service Mode. 5. Press the Refrigerator Temperature UP /+ Keypad again to confirm entry in the Service Mode. 6. The display will show 101 in left display and numeric or dashes in right display. 7. Press Freezer Refrigerator Temperature UP / + Keypad and Freezer DOWN /- Keypad to toggle through Service Test numbers. Service Test - 101 Defrost Heater & Defrost Circuit • Press the Refrigerator Temperature UP /+ keypad and Refrigerator DOWN /- keypad to energize or de-energize the Defrost circuit. The display will read OFF when de-energized, OP when energized with open defrost thermostat and CL when energized with closed defrost thermostat. 8. To exit service test mode, open and close refrigerator door or hold door alarm for 3 seconds. Read More...
Journey December 30, 2017 for Model Number KBHS179SSS06 My Kitchenaide convection oven operates normally but does not heat. The Magnatron measures 0.3 ohms across the terminals and an open between each terminal and the housing. Is this a good reading? Is there just one capacitor to short? I shorted the large canister one. Wasn’t sure about any others. Where is the diode located? Is it on the inverter board?
1 Answer Journey, The magnetron for this unit, based on the reading is good. This issue would most likely be caused by the inverter board which is part number W10217711. Read More...
Micah November 21, 2017 for Model Number KEMS308SSS04 Hello, I'm trying to fix my microwave so far with no success. I have replaced the magnetron, the inverter (both brand new parts), and the filter capaciter (round thing near power entry point). The only thing I can get it to do is get water warm. I place a cup of water in. Started at 50 degrees and came up to 120 degrees after 1 minute. When I place a bag of popcorn in it won't pop one nugget, but the bag is warm to touch after 4 minutes. What am I missing? I've checked the door interlocks, the thermostat on top of the magnetron, and the other sensor toward the front center and all give continuity. There are no error messages, but I have gotten f1e5 in the past (indicating a bad inverter). What can I check next?
1 Answer Micah, The f1 E5 error would be for a inverter board issue. Since the inverter and magnetron have been replaced it would be most likely a issue with the main control board that is causing this issue. Read More...
Paul February 01, 2017 for Model Number KitchenAid KHMS2056SBL2 Unit powers on but does not heat, or took a long time to get a glass of water to become "warm". I noticed the lights on the bottom of the unit flicker a bit while attempting the test. I assume its going to be a high-voltage-related issue, i.e., magnetron or inverter. I've opened the black housing to the inverter but don't see where to "drain" any lingering voltage out of it or a valid test. I don't feel comfortable testing the magnetron until I remove this board.
1 Answer Hello Paul. 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 trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron. Read More...
Mike R November 24, 2016 for Model Number KEMS308SSS05 Microwave not heating water --- looks normal but no heat -- no error codes revealed after pressing off,off,start. Suspect - diode, capacitor or magnatron. Where can I find some How To information on getting inside the unit to check these parts? Yes I know I need to discharge the capacitor first thing.

David November 13, 2016 for Model Number KOCE500ESS01 My Kitchen aid microwave shows an F1E5 MW In Exeter not real error message. I need part W10217711, do you supply install instructions w/part?
1 Answer David, Unfortunately there are not instructions that come with the part. The only way to change this part would be to remove the unit from installation and remove the outer cover of the microwave. This will give access to the inverter to be replaced. Read More...
David July 22, 2016 for Model Number KEMS378SSS00 gonna replace inverter board and magnatron. all research says to depleter the capacitor first. Does this model have one? I cant find it. Can I replace the board and magnatron after removing all power to the unit????
1 Answer David, When you get in the unit there will be a capacitor inside that the magnetron will connect to. In order to discharge the capacitor you would need to use a insulated wire or needle nose pliers and go across the terminals. Once discharged then you can change the magnetron and the control board.
