Please send instructions for removal and replacement of circuit board W10438752, so I can decide if I can do it. Thanks
Answer Hello Steve. 1. Unplug oven or disconnect power.
2. Open the upper oven door, remove the
two flat-head screws from the bottom of
the control panel frame, and remove the
frame. 3. Remove two keypad retainer screws on
right side of keypad. 4. Remove the three screws from the front
user interface board and remove the user
interface board from inner frame. 5. Disconnect wire connections from interface
board and remove.
I just replaced the control board and I'm not sure how the poly flex circuit connects to the other control panel.
Answer Hello Jim,
The ribbon cable connects to the long connector receptor at the top center of the control baord. Some of these have a built in locking mechanism. This is like a small plastic "clip" made on the receptor. The procedure to re-connect in this case is to raise the "clip" up away from the board, insert the ribbon cable, and while holding the ribbon cable in the receptor, slide the "clip" down toward the board. This will prevent the ribbon cable from slipping back out.
We ran the self clean cycle in our double ovens and they went out after and will not turn on at all. We just had a repair man out who quoted us 749 just for parts for what he said is the control panel and display? Our keypad looks fine...I see that the control panel is 274...is that all I need? Also, if so, can you send me step by step instructions on how to install it to see if I can do it myself? Thanks!
Answer Hello Mandy,
This is more likely the thermal fuse (AP3879224) than the clock and control. If you check from chassis ground to terminal P19-1 on the board with the voltage on and the meter set to the 240Vac scale, you should read 120Vac. If not, replace the thermal fuse. This is assuming that the breaker was flipped off and back on and proper voltage is being supplied to the unit. There is also a control power transformer that should be checked before ordering more expensive parts. This transformer is a step down transformer that provides power to the control circuits, including the units' readout. It connects to the control board at terminals P16-5 & P16-7 and the low voltage connections out of the transformer to the control board at terminals P16-2 and P16-3.
