John,
How much success have you had in finding the OEM M1 contactor? I’ve seen some replacements, but sizing an aftermarket contactor that has what 5 aux contacts, fits in the small original space and allows the drive door to close completely seemed impossible. At any rate, I think we answered Billm’s question. Sometimes companies do push obsolescence, but in a lot of instances, it’s the best alternative to aged equipment considering down times, parts availability etc.
