Gary for Model Number Duet purchased new in 2004 I looked all over the machine bur could not find a model number. The instruction booket didn't have a model number on it either only a place to write it in on the last page. I took the off and there were a bunch of numbers on the MCU but I don't think any of them are the model. Anyway, about a month ago the DL light would flash and the door wouldn't lock. A guy cam out and replaced the door latching mechanism to the tune of $200. He said if it happened again he would have to replace the MCU. Does that sound right to you? Is there something else I can do? I found puching the connectors on the board or wigging the board something causes the door to lock but I don't know if that really had an impact or just chance.
Answer Hello Gary. No, if the door is not locking properly and the wires can be moved and it work, it sounds like the harness is bad and not the control board. You need to replace the wiring harness on the unit. Read More... Answered by AppliancePartsPros.com | Monday, August 27, 2012
