By: Whirlpool
Part Number: OEM13073649
Manufacturer Part Number: W10211972

The Switch is an OEM part for Whirlpool microwaves. It controls the turning on and off of power to the microwave during cooking cycles as well as detects positions within cycles to signal appropriate actuations of the microwave's magnetron, fans, and lights. The switch is a crucial electrical component that facilitates the fully automatic operation of preset cooking programs.  

Causes of a bad switch can include wear and tear over time or unexpected surges that cause electrical component failure.

Symptoms of a bad switch include:

  • Cooking programs failing to advance properly or stopping mid-cycle unexpectedly
  • The microwave failing to turn on or experiencing power issues  
  • Random noises, humming, or lights occurring when the microwave is supposed to be idle
  • Buttons or controls acting intermittently unresponsive

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

Questions & Answers

For Whirlpool Switch (Part Number: OEM13073649)

1 Answer

Dave, the three short beeps indicate an invalid entry has been made. If cook method, time, and start are being pressed, the failure would most likely be in the user control WPW10391282. Unfortunately, this part has been discontinued by the manufacturer and is no longer available.

Amy, It would be recommended to first check the door switches for continuity as they can cause this issue. If the door switches are good then the issue would most likely be with the touchpad on the unit.

1 Answer

Susan, The first thing to check would be to make sure that the door switches are good. Then check to see if there is 120 vac to the transformer. If there is 120 vac to the transformer then the issue will be on the high voltage side. You can test the magnetron for less then 1 ohm of resistance and test the diode. If the magnetron has more than 1 ohm resistance it is faulty and if the diode has no continuity or continuity in both when the leads are switch to the opposite end then it is faulty.

Wael for Model Number KMBS104ESS02

Microwave oven will not start. The issue is intermittent. Sometimes it starts and sometimes it doesn't. During the state in which it is not working, the "start" button does not beep when pressed while all other buttons do beep normally. Interior light comes on and off normally when door is opened and closed. I have not opened the oven to test the door switches yet. At first I was suspecting the door switches but now I am not sure since the "start" button does not make a beep. Any ideas? If there was a faulty door switch would this cause the start button to not beep?

Albass for Model Number GMC305PDB07

My oven/microwave combo is a 2003 model Whirlpool Gold Accubake system model GMC350PDB07 with the microwave being model# AVM791. The display reads “Door”. I pulled the microwave out from its casing and looked inside to determine what the door switches were. The switch is a V5P110CG3 - 16A 1/2HP, and looked badly burnt on one of the pins. I can’t find a replacement on the internet. Is the W10211972 a suitable replacement? Or do you what know is? Also, I couldn’t determine what the other two switches were, but must I replace them as well? Thanks!

1 Answer

Hello Albass, There are three W10211972 door switches on this unit and as per the manufacturer if one needs to be replaced. the other two should be replaced at the same time. There are two on the right-hand side of the door and one on the left side.

Marv for Model Number KBHS109BSS00

I set time, power level and press start button. Display changes to show "Cooking", but light doesn't come on, carousel doesn't turn, magetron doesn't fire, and timer never starts counting down - basically, nothing happens at all (display doesn't change, either). Cancel button returns display back to normal default, though. Tried turning off at breaker (as that usually clears the numerous keyboard interface errors we have gotten since we bought the silly thing), but result is the same. Tried starting just by hitting the "Add 1 minute / Start" from the beginning, just to make sure it wasn't the membrane button itself that was faulty, but same thing - display shows "Cooking", but nothing going on. I have an electrical technology background, and have no fear of opening the unit up to troubleshoot/repair, but don't want to invest the time just to find out that the parts are no longer available (or that the board that needs replacing costs as much as a new unit). Thanks in advance for your guidance!

1 Answer

Marv, based on the information provided, as the unit has had several interface errors and is acting the way it is now, the likely failure is in the user electronic control W10434461. Unfortunately, this control has been discontinued and would only be available as part of the console assembly WPW10420954.

Brent for Model Number KEMC378KSS01

The display panel shows "Door" when the door is closed and the microwave will not turn on. I replaced both interlock switches and the monitor switch but it didn't solve the problem. I used a multimeter to check operation of each of the new switches and the old ones. They all appear to be working correctly. What else could be causing the problem? This problem occurred suddenly. One time it was working correctly and the next time we used it the Door message was displayed. I tried opening and closing the door multiple times, the message was always displayed after that point so it doesn't appear to be an intermittent switch. When I replaced the switches I was very careful to disconnect one lead at a time from the old switch before connecting it to the same terminal on the new switch, so I know they are installed correctly. This is for a Kitchenaid Superba wall oven/microwave combo.

1 Answer

Brent, if there is not a broken or loose wire, the failure would be in the control 8302346. Unfortunately, this part has been discontinued by the manufacturer and is no longer available.

Victor, with the power supply to the appliance turned off, the door switches W10211972 would need to be tested for continuity. With the door open, the dog eared terminal and the farthest terminal should have continuity. When the door is closed, the dog eared terminal and the middle terminal only will have continuity if each switch is operating properly.

1 Answer

Bill, You can test the door switches for continuity and it should change between door open and the door closed. There is a kit since the manufacturer suggests you change all three at the same time W10727408. If they test good then the control would have to be replaced and unfortunately it is no longer available.

You would want to test your door switches, this unit has three switches for the door, and if any one of the three fails it affects the operation of the microwave.
