Had a MHW6000XG2 with dryer stacked on top.
Got the dryer down. Manually unlocked door clothes appeared to have spun out.
Checked all the connectors on CCU. Unit will enter diagnostic's, but will not advance through diagnostic cycle.
I can program the unit for a cycle, but as soon as press start button error code pops up.
I called Whirlpool techline against my better judgement. He had me basically repeat test I had already done, I have 5vdc where I should and 120 volts to the MCU.
Which the wonderful advise of the Tech line was that based on readings it could be either the CCU or the MCU just have to replace one and see if it solves the issue.
I had asked about readings through lock solenoids on the schematic it shows a value of 50-75 ohms. The reading I found 130 ohms, they told me that was OK? In my experience its usually the MCU that causes problem. I was just concerned about the reading in the lock assy. The door will lock, just won't unlock on it's own.
Was planning on getting a MCU unless some new wisdom comes via this site
