QUESTION: Here is what I have done so far.

The oven light on our Amana model ACF3375A stove will not work.  I troubleshot the light socket and all is good there.  There is a red (orange)wire on one connector and two white wire on the other connector. I have continuity on the red wire from the socket to the connector that attaches to the circuit board. I have continuity on one white wire from the socket to the connector that attaches to the circuit board. The other white wire branches off and goes under the stove.  I did not check that one. I think I may have a bad switch although it does "beep" when I press it.  Can the switch only be replaced or do you have to change the whole circuit board?  Thanks.

ANSWER: IF your testing is correct, your should have 110 volts at terminal 3 on the ERC in the schematic and neutral when the light switch is turned to the on position.  Do you?  If you do, your troubleshoot is no valid.  If you do not, the ERC must be replaced.  I can honestly say I have never seen a light circuit on an ERC go bad as there is not much current draw compared to all the other circuits on the control board.  It is possible but before ordering from us or anyone else, double check your diagnosis...  Good Luck, Eric

QUESTION: Still not sure what the "Blue" is for.  When I pull the connector off of the back of the board the power goes out to the display on the front of the stove.  One thing I failed to mention is that this problem started when I was trying to get a burnt out bulb out of the socket and I was using a screwdriver and forgot to unplug the stove.  I got a spark from around the socket (may have shorted out the circuit). I may have "smoked" the light switch circuit.  Or you saying that I would need to change out the complete board?  If so, what do they cost and how hard is it to replace?  Thanks.

One of the relays on the back side of the electronic control have shorted.  Since the control is no longer available I would figure out which relay controls the light switch and try replacing that relay on the board....You can normally go to your local electronics store and purchase a relay.  Of course, the old one will have to be de-soldered and the new one soldered in.  Good Luck, Eric
