Craftsman Garage Door Safety Sensor Problem

16 years ago

I too have a Craftsman garage door opener. Mine is approx. 10 years old but it was never out of the box. I am having a problem with the receiver sensor. I've checked all the wiring and all is good. I even checked for voltage at the end of the wire at the receiver and it is good.I've tried adjusting the aim of both sensors and nothing works. I also tried my TV remote control and that doesn't work. I finally concluded I should purchase a new set of sensors but after hearing the older sensors had a problem when the temperature drops, I heard that a newer model was available that corrected that problem. Can I use the newer model with my older unit? My opener model is #139.53627SRT 1/2 HP and the sensor part number is #41A4373. Please advise.

I looked up the part number at Sears parts.com and your number 41A4373 changes to 41A4373A which usually indicates a minor engineering change. If this is not the number of your new sensors I doubt the new set would work.

Make sure the connections are tight where the wires attach at the rear of the motor unit. I would also pull the logic board and check for loose connections on the printed circuit. It could be the sensors or the logic board that is bad. Only by substitution can you be sure.

There is no way to add sensors to your old opener. The option available at the time it was new included a logic board. The logic board in your opener will not accept sensors.

Make sure the wiring is connected correctly. One of the wires from each sensor has a black trace. These must be connected to terminal 3 and the two plain white wires connect to terminal 2. If this is not the problem I would suspect the logic board.
