Greetings
I’m in the process of troubleshooting the control board on my whirlpool washer. The AC motor is having trouble starting - and when running is louder than it should be. It has two windings and I’ve found that one is getting 120v while the other is moves in the 30-60v range.
Each winding is supplied current via its own triac on the board. I’ve confirmed that both have 120v at MT1 - however MT2 is lower (30-60v) on on of the triacs when the motor is running.
I have no formal electrical engineering training and have been doing crash course research for this project. Is the lower voltage output a symptom of a failed triac or could it be intentional as a way of controlling the speed of the motor?
Thank you very much - I appreciate any help.
