You must be getting power to it or that orange light would not be flashing.
Lets double check for 120 volts coming into the machine control board.
You will need to take the voltage reading from the 120 VAC SUPPLY electrical connector, just remove the 120 VAC SUPPLY electrical connector and put your meter probes in it, and your meter should read 120 Volts.
If your meter reads 120 volts, and the STATUS LED is STEADY OFF, then your machine control board you ordered is defective. Make sure all your connectors to the machine control board are in place too.
See it on the right side of this photo below? Coming off the two yellow wire nuts, I circled it in red.
Why is it the Parts People don't know Jake from Adam??? The woman in customer service says no Jake works for them or with them. After much argument, she finally agreed to replace the board. She said I needed the UI part. Regardless, I'm getting a new control board shipped out next week. I am out of town ontil 5/23, so I won't be able to check the new one out until then.
After 23 days of being gone, I'm back at it. I installed the new board that parts sent me. The service LED on the board lights and remains steady on. No other lights on the UIB are on. I tried holding the cycle button on and down for at least 5 seconds, nothing. I tried holding the start button on for five seconds, nothing. I tried holding both the cycle and the start button down for at least five seconds, nothing. The result is the same whether the door is open or closed. Now what?
