I have a Whirlpool GS475LEMS1 free-standing gas range/oven.
Intermittently when the oven is in use, it will give an error and shut off. The error is either -F3- E0 or -F3- E4. According to the tech sheet, that's an open temp sensor on either the top or the bottom.
I purchased a replacement sensor and replaced the top. I still got the error messages, so I put the old top sensor in and replaced the bottom sensor with the new one. I still have the same problem.. It's not consistent -- sometimes it says the problem is the top sensor and sometimes the bottom. Sometimes the oven works fine and sometimes it doesn't..
I have tested all the sensors and nothing is open.. I get an appropriate (around 1KOhm) reading at room temp..
If I remove the connector from either sensor for a few minutes, the oven detects the open sensor and appropriately gives the error.
The oven maintains the temperature appropriately during cooking.
I have traced all of the wiring, particularly the common (tan) wire and connections to the control unit.. no loose, burned/damaged wires or visibly oxidized connections at the sensor or the board.. My unit has a warming drawer
sensor (which is oddly screwed in from the inside and also has the opposite gender connector from the other two sensor). If I disconnect that, I get the -F3- E6 error I expect but I never get the E6 code when the oven fails.
It doesn't seem like it would be a damaged control board since it's definitely reading temperature and works most of the time. Besides that, the cost of a new control board + the replacement sensor + my time is probably beyond the value of the oven which is 10+ years old.. Is there something I'm missing or something else I can try?
