Craftsman Garage Door Opener, opens/closes intermitently

The unit is about 11 years old and over the past six months has given us a lot of grief. Somedays it operates just fine. Others, it may or may not open/close using the remote transmitters. I have tried everything I know to do... which isn't a lot. I cleared out the codes in the remotes (both the hand held transmitters and the HomeLink in my wife's Pacifica) and I have tightened the sensors on the tracks. Still the smae problem. Anyone else having this issue? Anyone have an answer... short of replacing YET ANOTHER thing in this house?! In the past two year have replaced HVAC, water heater, dishwasher, stove, fixed dryer, fixed refrigerator, gee, what else? :)

Check all the electrical connections inside the unit. If it is intermittent it may be hard to pin down. Other than that you will probably have to add it to the list of Yet Another Thing. Depending on how often it is used 11 years can be past the life expectancy.

SOURCE: Remote will not operate garage door opener from outside garage

Will the remotes work in the garage? If yes but not outside with the door closed you might have radio interferace with your remotes. You might have to chage to a your reciever and remotes to a different brand (frequency). Sometimes it is less trouble to change out the operator. Chamerlain changed frequency from 390 (old) to 315 (new).

SOURCE: keypad garage door opener will not operate

what keypad are you using with new opener? Frequency has changed. can't use old one. you probably never needed to change things; just needed to follow proper coding procedures.

SOURCE: Garage door opener transmitter/receiver compatibility

The old transmitters are 390 mhz and will not program. I need more info on what you are doing to solve the homelink problem. Your vehicle's owners manual should show how to program. Then press learn button and within 20 sec press and hold homelink button that you programmed.

SOURCE: remote/homelink and touchpad problem

Your keypad is not the same "generation" as your remotes. You operator will work with your security plus remotes or your old keypad but not both. Yor cheapest solution is to replace your keypad.

Garage door only raises about two inches then stops.

Check the door springs and also remove the cover from the motor unit and check the drive gear. The door spring could be broken or the drive gear may be stripped.

The sensors only work when the door is closing.

The opener won't close. My husband said the sensors need to be realigned. Did that and still the opener halts after 2 inches and flashes the light? It is a six year old Sears Craftsman Chamberlain model?...

If the main light flashes 10 times it is a door sensor problem. If the main light does not flash then you can try increasing the down force. This is a control on the rear of the motor unit near where all those white wires go. If this doesn't help you probably have a bad infra red sensor board. This is a small printed circuit board just in front of the motor.

My craftsman garage door is about 8 years old. It

Make a slight adjustment to the Upward force on the side of the machine. Turn the screw a 1/4 turn each time and test, see if that helps. Also, make sure there are no obstructions or friction when the door opens and closes. Try it manually first.

Replace the logic board. I have seen this problem in the field. More often than not it's due to power surge or lightning strike.
