The problem I have is that the motor will stall, makes humming sound and the LED indicators for "open triac" and "close triac" are both on. There are two boards, the power board assembly,MK 1 p/n 01014 and the logic board assembly, MK 1, which board would cause this (its intermittent 50/50)?
What would it cost to repair the bad board and turn-a-round time estimate.
