Noticed the display on our 6-year-old Whirlpool RBD245PDS14 wall-mount dual oven was blank. Has not been used in days but it was on earlier in the day (we have a counter-top covenvection toaster-oven we use 95% of the time.)

Tried to get it to heat up but it beeped a strange sequence of beeps and nothing happened. Light comes on when you press the light button though.

Pulled it out of the wall, popped the cover, and checked all connections. It looks like new inside - again, we hardly use it - and all connections - to the board, between components, and especially to the supply are solid. I noticed, however, that I could get it to fire up after resetting the breaker, but only for a minute or two before it beeped that sequence of tones then no longer responded to input.

So I put a meter across the supply at the little distribution bus inside, 247 volts in idle, and with both ovens on (after cycling the breaker again) the voltage was only dropping 3-4 volts, so no issue with wiring.

I looked over the schematic and figured out that the transformer mounted away from the control board supplies power to it, so I checked the resistance - all was good there - and then voltage to the board - 25V - all good there as well.

So at this point I'm pretty convinced it's the control board. Anything else I can check to confirm that?  There doesn't appear to be much else in there, everything feeds off that one board with the exception of the little sister board mounted on the side, but it only has a number of small relays (?) on it.

Thx!!

Additional info: control board and display are one unit - display mounted to the back of the control board, soldered directly to it.

Also, if I do have to replace it, how the heck do you remove the black connectors near the big relays? I pulled the 4 red wires that have regular spade connectors easily enough, but the two black 4x1 connectors with two red(ish), two black wires are impossible to pull off the board..

Additional info: called several parts supply sources, none have it in stock, all say Whirpool has no part available currently, no ETA.

Dangit.

(trying to edit but won't allow)

Meant to include: of course, I checked here first, before signing up - they don't have it available either.

Says "normally ships in 14 days" but that is posted below every out-of-stock item on the site, so I don't believe that reflects actual availability.
