CHI garage opener

Geo-TH,In · Sep 27, 2012

My CHI 6500 1/2 hp garage opener is 10 years old. Never gave me a problem. It is chain drive. Has two stops attached to chain to flip a micro switch to stop opener when all the way up and all the way down.

Long story short, when the door went down, somehow it didn't flip the switch to a different position. The door went up, then wouldn't go down. It went dead like there was something blocking the sensors. All I had to do to make it work is flip the down micro switch, put it in the position it should have been, and it works like it should.

Never happened before. Thought I would post this weird event, in case someone has a similar problem.

Unhook the opener and check the door itself. Tension springs can get out of adjustment/lose tension and effect operation. Also check photo cells (if equipped) that should be near floor level on each side to see if they've moved. Check chain (if equipped) for adequate lubrication and function. And very commonly, rollers and wall track will wear and bind. Most quality door openers will be able to sense excessive loading and shut themselves down. I've had that to happen on what I'd best describe as an intermittent basis.

All the brands of openers I've had experience with have manufacturers tech service sites (be it email or phone) I'd try them for specific issues.

I have seen this twice:

The plastic shafts that the micro switches ride on, will get worn and slip. So your down goes down and hits the concrete but the switch doesnt see it, can happen on the way up too.

The plastic shafts are the ones you spin up or down to adjust when the door stops.
