Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Craftsman 53918 - 3/4 hp, belt drive garage door opener. Wall unit says safety sensors misaligned. Replaced them as suggested by manual, no fix. Does not appear to be any power from where you plug sensor wires into main unit. When pressing wall switch, main unit light flashes 10 times (maunal says 1, 2, 3, 4 or 5 flashes mean something, but nothing about 10 flashes). Can close door by pushing wall button a second time and holding until door is closed.\r\n Any suggestions?

The main light flashing 10 times is the sign of a door sensor problem. Check to see if the small light on each sensors is lit and not flickering. If you cannot get both lights to come on your sensors or the wiring to them is bad.

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.

How to program my garage door opener #53985 have to remotes and a wall button. Door keeps wanting to reopen after closing. Fred Haul.


Your problem has nothing to do with programming. It is one of two problems. Either the door sensors are misaligned or the door is traveling too far in the down direction and when it hits the floor the safety reverses it to the open position.

Make sure the door sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit.

The down limit adjustment is on the side of the motor unit. Turn it a bit in the opposite direction of the arrow printed on the cover.

It sounds like your door sensors may be misaligned. If when you try to close the door the main light flashes 10 times and the door reverses to the open position this is the case. Make sure the small light on each sensor is lit and not flickering. Tweak the sensors to see if you can get both lights to come on. If not you have a bad sensor.

Must hold wall unit to close garage door...


there is an error in the system. most likely The safety beams (mounted on the track near the floor) are out of alignment and the LED light should be blinking. The garage door opener will not let the door close if the beams are misaligned. Realign them and the LEDs on the beam or on the operator will stay on. you should be able close the door now with one push.

Brand new craftsman remotes don't work when garage is closed


Yes, it seems to be a frequency issue.  Craftsman usually guarantees 50 foot range on your remotes.  Contact Craftsman, they will probably work with you to solve the problem.
