I have a sears craftsman 1/2 hp opener, chain drive, about 9 yrs. Old. sensors, 2 remotes, wall switch and keypad switch. Works fine with all except the keypad switch. Lately the door will not go up when using the keypad switch. Goes down fine with keypad switch. Makes no noise, only silence. Looking for help. Thanks.:confused:

That's odd, sensors will allow opening, but can stop door from closing.
I would remove power(unplug for about 10 seconds) and plug back in, it may have gotten confused.

Thanks for the help. Turns out it was a worn out keypad. Bought another one for $40.00 from Amazon. All is good now.

Thanks again for your help.
