Specifically whether the mechanical control timers are interchangeable? I have an older GE washer that had the selector knob broken off during a move. I apparently can't get the same control anymore, and would have to send this one in for fixing, which could take months. I took the control off, and have found another unit off a Moffat that is physically identical, and has the same connections and power ratings. The only difference is where the programs are located, which I assume relates to the positioning of the cams inside. The wiring harness has wires connected to all the same pins, although I do not have a schematic of the replacement's wiring. My two options are: 1. replace the broken timer with the new one. The program positions will change, but that's fine. 2. Disassemble both units and swap the broken shaft out. Other than the broken shaft, there is nothing wrong with the machine, so replacing the whole machine is not a viable option. Any help appreciated.
