Sears Chain Drive Garage Door Opener
I have just replaced the chain drive gear and worm gear (plastic drive gear was broke in half)as per the instructions with the parts purchase.When I plugged the unit in, I heard a pop and it tripped the electrical breaker. I may have not had the wires in the motor starting capacitor installed correctly so I corrected them if in fact they were wrong. I got the same result, electrical pop, then a tripped breaker. Did I burn the capacitor up or do I have another problem?
