Whirlpool accubake oven problem
I tired the delayed bake work around and it didn't help me.
So, being a trained scientist... I know just enough to be dangerous! Here's what I learned. (imitate me at your own risk. This thing is on a 220V circuit at 30A... you or someone else in your house could get badly killed if you do something wrong. You definitely want to send small children to the movies, or at least to bed before trying this!)
First, I turned the self-clean on for 60 seconds to see if both elemets were working. The broiler got bright red but the bake element didn't. The door unlocked as soon as I shut it off, so I could I touched an ice cube to a few insided parts to see how hot they were. The bottom of the oven was barely warm, but the baking element instantly melted and sizzled my ice cube.
Good enough for me: Both heating elements are working, so it must be a controller problem.
Next I turned the power off at circuit breaker, and double checked that the oven was dead. I pulled it out of the wall and removed the top sheet metal cover. Inside I found a red plastic envelope containing a "Tech Sheet". It has a schematic diagram, plus a table that explains the error codes and what to do about them. Be sure to read all the dire warnings and the bit about "For Service Technician's use only" before deciding that you are foolish enough to do anything with it. :-)
I undid and inspected the connector for the printed ribbon cable from the keypad to the controler circuit board. (I happen to know, being a scientist, that 90% of all problems in the universe are caused by bad contact) I didn't see anything obviously wrong, so I reassebled it carefully, making sure the ribbon was fully seated.
I then powered the thing up. It said PF for power failure. I pressed cancel for 5 seconds and it said F0E0 which means no pre-existing fault was detected.
I then pressed bake, and lo and behold the damn thing baked! :-)
I'm not certain it was bad contact, since the other 90% of the world's problems are caused by software. It's entirely possible that power cycling was this thing's idea of CTRL-ALT-DEL. Maybe someone can try flipping the breaker off for 10 minutes without taking anything apart, to see if that clears the problem?
I also have no idea how long this will stay fixed....
Has anyone tried calling Whirlpool? 1-866-698-2538, M-F, 8 am - 8 pm Local Market Time, Sat. 8:30 am - 5 pm Local Market Time, according to their website.
Stay tuned... if I'm not back, the thing is still baking... :-)
