The Oven Thermostat is an OEM part for GE ovens. This thermostat is a component in regulating the oven's heat, turning the heat on and off to maintain the desired temperature setting. With its precise calibration and durable construction, the oven thermostat is essential for achieving consistent cooking outcomes and preventing overheating, which could lead to burnt or undercooked food.

Causes of a bad oven thermostat include prolonged use, which can affect its sensitivity, and exposure to extreme temperatures, which may impact its accuracy.

Symptoms of a bad Oven Thermostat include:

  • The oven not reaching the set temperature
  • Oven temperature fluctuating too widely from the desired setting
  • Food not cooking evenly or within expected time frames

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

Questions & Answers

For Ge Oven Thermostat (Part Number: OEM7869228)

S.J. for Model Number 36273219203 Sears Kenmore Range

My stove would not turn off when in the off position and had to be unplugged to stop the heat as the igniter would still be illuminated given off heat. I called a repair guy who said it was an igniter problem while I disagreed stating it was something to do with the knob communication to the igniter (i.e. the thermostat). The repairman insisted it was the igniter and replaced it for $173. The problem of the stove not shutting off came back and again I called the repairman stating it would not turn off when in the off position. He comes back to tell me I need a thermostat which was what I said was the issue in the first place. Now he wants to charge me $80 for the thermostat. I see these parts cost about $35 each and conclude I am being overcharged for a part I never needed (the igniter) and asked to pay $80 for the thermostat. Is it possible that the repairman would pay more for these parts than what I am now seeing online? Your thoughts please. I'm contemplating getting my money back and just buying a new stove. Thanks!

Hello, This was definitely not an ignitor issue as the ignitor obviously worked. I agree that the thermostat probably has stuck contacts inside it. As a trained professional, I know better than to get in the middle of an issue between a customer and a servicer, while at the same time it is common knowledge that a servicer normally will get their parts for wholesale, and marks the parts up to retail. Retail is the prices listed that the public pays for the parts. It is also common knowledge that servicers mark the prices up in order to try to stay in business, while at the same time, if they mark the prices up too high, it is frowned upon by the industry.

Kevin, Based on your post description, you're on target. It's very likely you damaged the internal contacts of the thermostat, when you removed the knob. The WB20K8 is a good place to start, and will solve the issue, most likely. Thanks and Good Luck

Hello Devin. If the burners are lighting properly, but the temperature inside the oven is not correct, you will need to replace the thermostat WB20K8. Hope this helps.

Hi Dan. Remove all power. Remove grates. Remove drip pans. Lift the top and support with support rod. Remove the door. Remove the knobs. Unscrew the screws that hold the thermostat. Remove the screws that hold the front control panel. Remove the panel. Mark and unhook the wires to the thermostat. Uncoil the new thermostat capillary tube as straight as possible. Unhook the old capillary bulb from the holding hooks in the oven cavity. Remove the back panel and back control panel. From the back of the oven, pull the old tube out. Remove the old control completely. Assemble in reverse order. Make sure you thread the tube back into the oven cavity as straight as possible. Make sure insulation is wrapped back in the hole between the 2 - oven inner/outer cavities. Make sweeping curved bends only. The thermostat part # is WB20K8. Thank you.

Hello C Dale. The oven thermostat WB20K8 is located in the control panel, and goes into the oven cavity. You will need to remove the control panel and the back of the range to access and replace the oven thermostat. Hope this helps.

Hello Jac. Based on the information you provided, it sounds like the thermostat WB20K8 is bad and will need to be replaced. You can test and see where the power is coming from. Once you determine where the power is coming from, you will need to replace that part. Start testing from the igniter and go backwards. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps.http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
