What timer would we need for this model and serial number?
Answer Hello Peggy. Based on the model and serial number you provided, 22003361 is the correct timer for the unit.
When replacing old timer with new timer, does the wiring harness pull out or unplug from old timer?
Answer Hello CL. Yes. The wiring harness has a locking clip that has to be depressed and it pulls out of the timer 22003361 with minimal force. It has to have some pressure on it to make electrical connection. Hope this helps and have a great day!
