I have a garage door opener, model HBW0777. What is the part number for the safety reversing sensors.
Sears reversing sensor on Model hbw0777 not working. Green light is on the sending unit, but not on the receiving unit. Have checked conductor for breaks. When I try to close door, opener reverses and light blinks repeatedly. Are there any other tests I can perform other than replacing the sensors?

Bob, The model of my unit does is not like 139.xxxxx. It is a sears unit with the model number as stated in my original question. I also thought this was a strange number, but I copied it directly from the unit. I will try your suggestion to test the unit. Thanks
