I have a GE double wall oven, less than two years old, lightly used, which is displaying PF97 code. The oven was fine until my wife used the self cleaning operation.

Hello there,

This may be related to the F7 problem even if you are not getting an error message. Go to my web site at the following link:

Please let me know if this works for you. I have sent my fix to over 1300 folks.

Good Luck,

Powerman

Unplug it or turn off the breaker

The first time we used our Whirlpool oven the same thing happened - no power and yet the circuit breaker was not blown. I called Whirlpool, and they sent out a technician to check it out as it was still under warranty. He said the temperature was off (too hot) by 20F - he adjusted. He also replaced the blower. What he did not tell me was that the thermal fuse had blown, and he replaced it - this was the REAL cause for the failure. I got the impression that he did not want to let me in on the secret. He did not note on the paperwork that he replaced the thermal fuse. Last week I decided to run the oven through the self-cleaning cycle (the oven is now 8-1/2 yrs old) - I don't believe that we cleaned the oven but a couple of times since the first time that it was "repaired." I used the default 3-1/2 hour setting. Everything appeared to be fine - the oven went through the cleaning cycle with no apparent problems. The display now read "cool down" - I went to bed thinking everything was okay. I got up the next morning only to find out that the power was out. I called Whirlpool and demanded that they repair the unit again as they clearly never fixed it correctly in the first place. They offered me 15% off on a new oven - WHOOPEE! I asked to speak with the supervisor - he did not budge either. I was upset, and I told him that I would NEVER purchase a Whirlpool appliance again! I decided to tear into the oven to see if I could detect anything wrong. I pulled out the front panel - everything looked okay. I then noticed the "thermal fuse" - I did not know what it was called at the time, but it looked familiar. I checked voltage on either side of the fuse and found the voltage to be zero on the downstream side of the fuse. I pulled it out and read the information on the device: Microtemp 110C. I called a local appliance repair shop - they told me that it would cost $50 to purchase a new fuse! I told them that seemed very high. I ended up stopping at Radio Shack. They have thermal fuses in various temperature and voltage ranges. I got a 144C 10A fuse and carefully soldered the connectors to it and replaced the protective plastic sleeve. I actually bypassed the thermal fuse in order to use the oven before I found the replacement fuse. While it is a good idea to have a protection device for the slim chance that an oven may malfunction by overheating, it is not a necessity for the functionality of the oven. Hopefully, the thermal fuse will not fail during my next attempt to self-clean the oven. I do have a concern about the 10 amp rating, but I'm sure that it will work fine.

Self cleaning features are not recommended by most appliance technicians. The ovens are not constructed satisfactorily to expel the 1000 degree heat, Therefore the thermal fuses blow as well as other parts failures.
Remove the oven. Remove the rear panel. Replace the thermal fuse in the back of the oven. Use Easy Off next time.

This is a lock switch error code. Check wiring to door lock switch (the wire harness may be connected wrong). Check for stuck lock switch. If the switch cannot be re adjusted, it must be replaced.
