Home Repair & Remodeling : How to Troubleshoot Garage Door Openers

[stydel311]

i have a lift master 3/4 hp opener on a steel door (not insulated). The opening unit is about 15 to 18 years old, and therefore, doesn't have the infra-red sensors at the bottom. It works good, but not. The door will randomly stop in the middle of up travel and is adjusted correctly, if you hit down and back it will go back up to the fully up position. It also goes back up randomly, also adjusted. Both up and down are set to full force, and it has been grease and lubed recently. and ideas?

Was wondering if you might have ideas on what may cause an electric garage door to only work intermittently. At times it works fine & other times I'll use my remote to raise it - or lower it - & it will stop halfway thru & I have to raise or lower it the rest of the way manually ; Also maybe a coincidence, but it seems like it's more of an issue in colder weather. Can't be the batteries because the issue is with both remotes I have. Any ideas welcome

@scoutre44 I think the cold weather makes the springs tighten up. I increased the torque up VERY SLIGHTLY and that should give it more power to open all the way. I am no professional but had the same problem and found that answer. The setting should be somewhere on the motor.

Thanks for the great advice Tim. I was able to troubleshoot and fix my garage door this evening. I'm still not sure as to why it suddenly would not open more than six inches off the floor.

On another note, have you ever done any tutorials on how to fix a leaky faucet? I'm working on a PFister kitchen sink, model # 133. I'm having a difficult time removing the plastic retainer ring without damaging the plastic itself. Any thoughts?

I have a Craftsman door opener that will close for about a foot then open up.

I pulled the cord to disenagaged the inner trolley from the outer trolley. I then manually close the door

about half way. I turned on the garage door opener switch/remote. The inner trolley rolled to meet and engaged the outer trolley. The door was able to close.

What could be the problem? I have a sectional door. There is no problem opening the door.

I fixed my half opening only doors by just giving the track overhead a lite shot of WD-40 thru the red straw! That made the darn thing work like new again! Do Not make adjustments to the up force settings till you try this first. Remember the secret ingredient in WD-40 is fish-oil. Amen

Sounds like a broken spring.

Or your cables just came off and they need to be put back on, consult a pro when dealing with torsion springs and tension.
