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.

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.

LIFTMASTER REPLACEMENT SAFETY BEAM KIT IS VERY EASY TO INSTALL AND ONLY TAKES A FEW MINUTES TO INSTALL ONE ABOUT 10 MINUTES IN ALL. EVERYTHING YOU NEED IS IN THE BOX. VERY REASONABLE COMPARED TO OTHERS I LOOKED AT. HIGHLY RECOMMEND THIS PRODUCT FROM THIS SELLER. WOULD DEAL WITH AGAIN AND AGAIN. I BOUGHT THIS FROM AMAZON

It worked as expected on my liftmaster 3585. Just needed to cut the old one out and put the new one in. Took less than 20 mins to finish the job.

It took me about 10 minutes to install these and my garage door worked. The installation was quick and easy.

Perfect fix. I'd be surprised if this safety sensor is not the very same one Sears sells as original equipment. If fits the mount perfectly, and works perfectly. Purchased on Amazon for half the price on the Sears website.

The product recieved was exactly what I saw online plus I recieved it sooner than what I expected. Will buy again from this seller in the future

This replacement part was exactly what I needed. It was economical, the vendor sent it promptly and it arrived without incident. I am very satisfied.

Our garage door had problems closing. Initially, it started out because of the daylight shining on one of the sensors, but after a while, the door wouldn't close regardless of the time of day/light. I spliced these sensors into my existing wiring and it's been working great ever since. It took about 5 minutes to change the sensors.
