This unit was easy to install and fixed my old craftsman garage door opener model 139.53962SRT.
I learned a few tricks in the process

These are some general troubleshooting steps:

1.- Check the wiring first. Be sure wires has not been damaged. With ohm meter check for open circuit or short circuit.
2.-Disconnect the receiver and sender units. They both connect to the same terminals. Terminals 2 and 3 in my opener. Be sure to label the wires to be able to reconnect them later. Measure the voltage in the terminals. It should be around 6 volts DC. Terminal 2 negative. Terminal 3 positive. If there is no voltage the control card in the opener is defective. This kit will not help in that case.
3.- Reconnect the sender unit first. Its LED light should come on. If it does not, the sender is defective. Replace the sender.
4.- If the sender LED comes on, connect the receiver unit. The LED light comes on when it detects infrared light. Point the sender to the receiver. The receiver LED light should come on. If it does not try with a TV remote. TV remotes emit infrared light also. Point any TV remote to the receiver unit and press any button. The LED light in the receiver should light up. If it does not. The receiver is defective.

This kit includes a receiver unit, a sender unit and hardware to install.

This review is from: Liftmaster 41A5034 Garage Door Opener Safety Beam Kit (Misc.)

When I was pressing the garage opener, the motor was getting stuck and the bulb would blink 10 times - indicating some perceived obstruction on the safety sensor infrared light beam path. My safety sensor sender side yellow light was on - the receiver side green light was not turning on after multiple tries at alignment. Then I read on one of the reviews that you can use the television remote to check if the receiver is working - right on the green light on the receiver came on. After checking all the wires for loose connection, came to the conclusion that the sender side infrared source might have gone weak.

Got part number from owner's manual. Checked on amazon and came to this product. We got the kit within two days (after paying for the 2 day shipping). I was able to cut and splice in the new sender unit and the door started working immediately after that.

Received kit within a week. Replaced old photo eyes with these and worked perfect. If second door fails, I'll order these again.
