Garage Door Reciver Only Works From 2 Feet Away

I have not repaired it yet but from what i have read it seems to be the main logic board in the garage door housing it s looses memory if i don t use it overnight.

Garage door reciver only works from 2 feet away.

I bought this new in the box from a guy up the street from me that bought it new. This unit is called the liftmaster 850lm universal gate and garage door opener receiver and is available for right around 40 dollars and will solve your garage door opening issues. As most garage door remotes work only about 20 feet from the opener this unit will make it so you can open your garage from up to 100 yards away. In the morning i have to click the remote 10 or more times to open the garage door and when i come home it works from three houses away.

The fact that it s not just not working but instead only works at uselessly short distance has me confounded. It s a craftsman 1 2 horse model number 139 53995srt mfg date 10 02. It was still in the box never used. I ve replaced the batteries in both the remote and the keypad.

I thought it might have been the new wireless router that i had installed a few. If the remote works only when held within a few feet of the motor unit rf interference is probably the problem. This will now make your garage door opener smart and you now have the ability to monitor open and close your garage door. The push button opener mechanism is fine and operates manually as always but not being able to trigger it from outside the closed garage door is obviously a pain in the ass.
