Oven has had occasional problem since new (3-4 times over two years)where it would suddenly display "PF" and turn off in use. Now, the display has gone completely dark and oven appears to have no power. Resetting the breaker has no effect, however leaving the breaker off for several hours then turning back on results in oven working again (temporarily). Oven will "go dark" again, even if not used at all.
What should I check - control board? Thermal fuse?
Any insights appreciated…

Look at #37 on the oven breakdown of your product. It is the thermostat, and it is located in the back of the oven. If you pull the oven out, and take the back off, you will see the thermostat. Make sure the oven breaker is off, and take the 2 wires off the thermostat, and put them together, and put some tape around it, so it does not hit metal, and turn the power on and see if it works. If so DO NOT run it like that, it is for testing reasons only. If it works replace the oven sensor, and the thermostat. If it does not work replace the board.
Thanks, guys…
Interestingly, the problem recurs wihout the oven being used (not heating up).
Last night I tripped the breaker back on, the oven came back in "PF" mode as expected, I reset the clock, and all was fine. This morning there was a clicking sound, then the display went back to "PF". Oven hasn’t been used at all.

I agree with denman - there is an intermittent power interruption, most likely on the low voltage power supply side for the control board. Possible a micro crack somewhere or a bad winding in the low voltage transformer which breaks as soon as it heats up.
The oven shutdown thermostat, mentioned by Tom, in case if it’s blown will interrupt power to the heating elements only.

Yeah, it’s looking like it must be the control board. I got it working again for a few days, then it just went dark again. Heat doesn’t seem to be an issue, as it does this when the oven is never even turned on.
Can I get at the control board without pulling the oven out?
Thanks again.

The low voltage transformer is heating up as long as the oven powered up.
Yes, you can. Just open the control panel.

We are glad you were able to fix it. Happy New Year!

Good Job!!! Its a good thing you didn’t have to cook christmas, and new years eve dinner!!! Tom
That is a different kettle of fish, if only the suppressor is burned.
I would disconnect the spike suppressor and then try powering the unit up without it.
Perhaps it is the culprit.
In any case you have nothing to loose.
If the unit comes up and runs then all you have to do is order and replace the suppressor ASAP.
Could do it that way, but I thought the spike control was bolted to the terminal strip and then the wires attached to the terminal strip bolts.

It may be time for a pro.
You should check the voltage output of the transformer.
I do not know what the output should be, it may be marked on the transformer. If you cannot determine what it should be, then it should be checked with the transformer connected to the board and then disconnected to see if the board is pulling down it’s output.
If I was doing this I would disconnect the various plugs going to the board so all that is left is the board and transformer and see if it comes alive.
If it does then components have to be checked to find which one is causing the problem.
If it is still dead I would still check components just to be sure one of them does not take out the new board.
The above is probably overly cautious but I am a firm believer in safe instead of sorry. Odds are high that it is just your control board but not 100%.
Also I do not know what your series of beeps mean.
I am off to the lake for a couple days so I am going to ask for help from others in the tech section. With luck one of them will have additional suggestions and/or know how to interpret you beeps.
You are welcome. We are glad you were able to fix it.
Unfortunately there are no a such symptoms, but you are protected at least for a year with great APP parts warranty.

The model number you posted is incorrect. Verify and repost it.
