In testing my recently purchased backshop, I found that the roll up doors were binding because the corrugated plastic material had hardened with age, becoming stiff and discolored, so brittle that they snapped into shards. I undid the four screws holding the motor in place and lifted it above the rack gears for test purposes, and the motor itself operates correctly in command mode when the direction button is pushed to activate it. The sound comes on and it responds to the limit switches if I manually activate them. If I hold the drive gear simulating a jam, the motor reverses direction. The machine sounds turn on and off using aux1+9 for on and aux1+8 for off, but the machines run all the time, so I suspect their driver has failed.
Does anybody know of a source for the corrugated plastic to make replacement roll up doors?
regards, Paul
