I will assume you are talking about a garage door opener. The problem is that either the sensors are misaligned or a wire or wires have become disconnected from one of the sensors, or worst case, the main unit is bad.

Visually check the 2 sensor units at the bottom of the track near the floor of your garage. When they are properly aligned the LEDs will be green on both units. If misaligned (or when something is blocking them) one of the LEDs will be orange. If either of the LEDs is off, the problem is in the wiring or main unit. The wires are marked with black or red stripes and must be connected to the matching screws on the main unit.

I have a Sears craftsman model 139.53637SRT garage door opener. My remote has not worked in a long time. I use the wall control button and have to hold the button in order to open or close the garage door....


It sounds like your door sensors may be bad or misaligned. Make sure the small light on each sensor is lit and not flickering. That could be the cause of your having to hold the wall button down until the door is closed. You can buy a universal remote but if you only had one remote before it could be the receiver that has quit. A new remote would not fix that but the only way to find out is to try.

I have no idea what a 132C2105-3B is but try this. Hold the button down on the remote and then press and immediately release the smart/learn button. If the remote is the correct one for your opener it should work.
