Mark March 25, 2026 for Model Number JKS3000SNSS Hello. Oven turns on and blower starts then immediately stops. Oven heats up but without the blower running = abnormally quiet. I replaced the blower motor assembly with no change in the issue. There are no codes. What’s the next step? Temp sensor? Thanks for your time and help! Cheers, - Mark
1 Answer Mark, WIth the blower being new but not coming on then this will be a faulty control board WB27X36809. Read More...
Jacquelyn December 25, 2025 for Model Number JT3000SF2SS Bought a temperature sensor from you a year or two ago. It’s started acting up again. Baked at 450 for about an hour then got f20 error. Turned off then back on and f20 kept coming back on. Flipped the breaker and worked til I finished cooking. Did seem to see smoke around top of oven. Could not tell if coming from burn unit or sensor?
1 Answer Jacquelyn, You would want to test the sensor to make sure that it is good. You can test for 1090 ohms at the sensor. If the sensor is good then check the wiring between the board and the sensor. If the wiring is good, you will want to check the oven bake element to make sure that it is good. It should have a resistance reading of between 15 and 25 ohms of resistance. If the element is good then this will be a control board issue. Read More...
Chris March 23, 2025 for Model Number JK3800DH2BB My oven keeps throwing Thermal Sensor error code. I replaced the lower oven temperature sensor already but it still shows up randomly. Sometimes it will happen in the middle of the night and then it'll go away on its own. What could be causing it? Is there a different sensor in it? Or could it be due to a defective mother board?
1 Answer Chris, This issue will most likely be an issue with the control board WB27X32625. Read More...
1 Answer Michelle, the error F20 is going to indicate a thermal runaway failure in the upper oven. This could be from a bake WB44X21667 or broil WB44X48685 element being grounded out, the oven sensor WB21X10165 improperly measuring temperature (it should measure around 1100 Ohms at room temperature), or a failure in the oven control WB27X25351.

Jim January 04, 2025 for Model Number PT7550SF3SS I get an F20 code that comes on randomly with the oven off. I also got an F34 with the oven off. I have turned the power off for several minutes and one of the codes comes back after aa while even though neither oven has been turned on. What could be the problem?
Larry August 18, 2024 for Model Number PT7550SF1SS 1. Lower oven light stays on. 2. Lower oven heats only to 140 deg.
1 Answer Larry, 1. Lower oven light stays on: Check that the door is closing completely and that the door switch is functioning. 2. Lower oven heats only to 140 deg: Use a multimeter to determine if the bake element is receiving 240vac and that the element is good, and check the resistance of the oven sensor for approximately 1080O at room temperature.

Susan Carroll March 30, 2023 for Model Number PT7050SF2SS Getting F30 code on my wall oven. Trying to identify what part(s) are needed to repair it. If you can help, thank you in advance.
1 Answer Susan, The F30 error code indicates an upper oven sensor is shorted. You would need to replace the sensor and check the harness between the upper oven and the control board. The sensor part number is WB21X10165. Read More...
Claire September 16, 2022 for Model Number CT9070SH4SS Self cleaned oven now I have a F92 code. What is wrong with the oven?
1 Answer Claire, The error code would be Upper oven unlock home and lock home are true simultaneously. Check the door lock and harness between the loc and control board. If the lock and wiring check ok then replace the control board. Read More...
Ed September 05, 2022 for Model Number JT1000SF3SS When baking, the oven will suddenly begin beeping and F2 is displayed on the screen. Whatever is baking will be scorched on the top, making smoke billow out of the oven. Dangerously high heat. What part(s) do I need?
1 Answer ED, The F2 code means the oven temperature is too high The oven is detecting that the temperature inside the oven has exceeded a preset threshold. You will need to check the oven sensor and or the oven relay/control board. Read More...
Jason August 10, 2022 for Model Number JT3000SF3SS Temperature runs about 50 degrees below set temperature.
1 Answer Jason, with the power supply to the appliance removed and the sensor WB21X10165 disconnected, the sensor would need to be tested for resistance. At room temperature, it should measure 1100 Ohms. With a thermometer next to the sensor, a hair dryer can be used to heat the sensor up and it should increase by 2 Ohms for every 1°F it heats up. If the sensor measures good, the main control WB27X25322 would be the cause of failure. If the sensor does not test good, the sensor would need to be replaced. Read More...
