We bought sensor WB21X5301 for our oven for the F3 Error. I want to know is problem really the sensor and what is the difference between low cost sensor and the expensive one? Thank you
Answer Hello Mah,
There is no difference from one sensor to the next other than the length and the connectors placed on the wires by the manufacturer. The F3 fault code can be caused by the temperature sensor, a bad connection between the sensor and the control board, or a bad control board.
Oven turns ON and then shuts OFF 45- 60 seconds later.
Answer Hello Stan. It sounds like you need to order and replace the control board on the unit.
Hi, F3 error code. Ordered cheap sensor didn't fix the issue.
Answer Hello Mah. We will need your model number to help you with this. Please call 1-877-477-7278 or post your model number with a new question on the parts page. http://www.appliancepartspros.com/modelnumber_locator.aspx
Getting error code F-2. Replaced Sensor assembly and now get error code F-3.
Where can I purchase the control board?
Answer Hello Ken. Sorry, the part needed WB27K5190 has been permanently discontinued by the manufacturer and we don't know of any source or replacement for the part.
We were having problems with the keypad (2 and 9 didn't work) and getting an F3 code. Also the temp of the oven wasn't getting as high as we set it for, so we had to trick it by setting it at 400 to get 350.
I replaced the keypad. That solved the 2 and 9 issue, but we still got the F3.
Then I replaced the oven sensor (the metal probe that sticks into the oven thru the backwall and plugs in to the wiring) The oven seemed to work fine for a week, but now we're getting F3 again. Argh! What next oh wise ones?
The F3 is an open or shorted sensor circuit which could be the result of contamination on the terminals, pinched wires in the sensor circuit or cold solder joint on the control. You will want to do a resistance check of the oven sensor which should be 1100 ohms at room temp of 72 degrees. Also check the continuity of the wire harness from the control board to the oven sensor and make sure that there is continuity there and visually inspect the wires for damage. If all this checks ok then replace the control board.
When baking at higher temperatures 350+ the oven will heat to temp and after awhile beeps giving a F3 error code usually. Occasionally has thrown F4 and F5. After hitting Clear cannot immediately restart oven. After waiting about 10-minutes or so, can restart oven and the cycle repeats. When baking at lower temps the oven runs normally. Is this likely the Sensor or Control Board?
Answer Mike, The F3 and F4 Error codes indicate the issue is in the oven temperature sensor [ ] This can happen in older ovens, and after a self clean cycle. The F5 error code indicates an issue in the ERC/Clock, The "watchdog" or checksum circuit. But based on the post and since the issue is at higher temperatures only, start by replacing the oven temp. sensor, and check the wires, connector for damage.
