It sounds like a case of your keypad losing signal strength enough that it cannot transmit through the closed door. If a new battery doesn't do the job a new keypad will.

What does the purple button light flashing on 1/2 horsepower craftsman garage door opener


I think the adjustment mode is on.

For example, that's from Craftsman manual:

""
Setting the Force
The force setting button is located on the left panel of the motor unit. The force setting measures the amount of force required to open and close the door.
1. Locate the purple button on the left panel of the motor unit (Figure 1).
2. Push the purple button twice to enter the opener into Force Adjustment Mode (Figure 2). The LED (Indicator Light) will flash quickly.
3. Push the remote control or control console (Figure 3). The door will travel to the DOWN (close) position.

Actually, you should just read carefully your garage door opener unit's manual.

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.

Garage door only closes halfway


If the main light is flashing 10 times when the door reverses when closing it is a door sensor problem. You can override this with the door control but not with a remote. Make sure the door sensors are pointed at one another and the small light on each one is on and not flickering.

My access Master 350 will not open or close when using remotes


If the light in the wall control is flashing your opener is in the lock/vacation mode. Press and hold the button with the lock icon for 3 seconds. If this is not the case your logic board is bad.

Craftsman # 139.53879 -1/2 h.p. Door opener- problem re-programing remote unit. Garage door will open but not close using remote. Wall switch works fine to open & close.


Check your door sensors. They must be pointed directly at one another and the small light on each one must be lit and not flickering. If by tweaking them you can't get both lights to come on you may have a wiring problem or one of the sensors has quit working.

Sears 1/2 hsp garage door opener. Remote control will not close garage door until light goes out. what is problem ?


I would suspect you have a light bulb that is radiating and causing interference with the receiver. Remove the light bulb and try. You can also try this: Unplug the unit and using a small screwdriver pull out on the center connection in the light socket. This will tighten the connection and prevent arcing.

My Craftsman remote won't close my garage door


If the remote opens and closes while inside the garage but not outside , there are a few things it could be. Assuming it was working fine before..
1. weak battery in remote.
2. remote itself could be bad. (unless you have more than 1 remote acting the same)
3. Logic board in opener is going bad causing limited range.Is the wire that hangs down from the opener straightened out? That is your remote antenna.Some people have coiled or even cut it off..reducing range.
4. Less likely but this can happen- interference from another electronic device, wireless routers, cell phone, new appliances etc.. can reduce remote range. Any new electronics recently purchased?

If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.
