Sears Garage Door Repair
I have replaced the gear on my Sears Garage Door opener. The door will start to close and after about 2 sec. it reverses and opens. I have read several discussions concerning the sensor on the end of the motor shaft and the motor shaft coupler. I have adjusted the coupler on the shaft and moved the shaft of the motor as far back as possible, the sensor is on the end of the shaft. It will not work. Any suggestions.
