I have a 7 year old Chamberland opener. The other day it made a funny
noise and wont move the chain at all to put the door down or up.
Is this repairable? Or am I going to have to go buy a new one? I am
trying to watch money as I have a 4 month old at home and did not know
if this was somethign I could repair myself or not.
Might also be lubrication problems. Read the owners manual, or do some
netsearch. Many times when motors don't turn, they need lubrication. I have
disassembled a lot of electric motors, cleaned them out with solvent, and
Might also be that something in the gears or chain needs lubrication.
I had the same symptoms. Took it apart, found nothing wrong, put it back
together; it ran for about 2 cycles before not working. Tried it again,
same results. The third time was too much; it never worked again.
Contacted Chamberlin and asked if it was the capacitor. They said, sure,
I replaced the capacitor. Didn't help.
Bought a new opener.
I hope you have better luck.
Check it again today. Perhaps you overused the opener by opening and
closing the garage door repeatedly, and possibly the motor shut down
due to overheating. It may start working once it cools down. Happened
to me once.
there is thermal shutdown circuit in the motor. If it is
hot, it won't run....
Might be that the pin holding the sprocket to the
gears has broken... The gears would spin,
but the sprocket is loose on the shaft.
Open it and see what the problem is. They
are simple machines.
You have 1)R/C circuits (remote control)
2) motor driver
3) limit switches.
The limit switches are connected
to the gear box.
The one time I fixed a garage door opener it was a broken drive belt. Up a
ladder, remove the case screws, and have a look. It was a Sears unit, and
they sold me a new belt for a couple bucks. Replace belt, and we're good to

Can you pull the disconnect & move the door by hand?
If not, it may be one of the tension springs that help lift the door,
assuming you have that type of door.
The spring looked OK at first glance, but if you looked closely, it
was broken. Was an interesting process watching &helping the door
repair guy! And no, I would not have attempted to replace one of those
coiled tension springs myself then..but now I might! ;-)
The time this happened to me, it was a stripped plastic worm wheel.
"Anything can be repaired" is correct, but you are in for an interesting
machining task, if that is what it is.
I replaced it with a Genie screw drive, which I like quite a bit better.
Check for worn plastic gears in the unit. Also, confirm whether correct
springs were used for offsetting the weight of the door. With the drive
disconnected via the "pulldown disconnect", very little force should be
required to open the door. Similarly, the unit should see very little
load when operating, otherwise, accelerated wear takes place. Homedepot
(if you're in the US) sells springs if it's necessary to repalce them.
If the gears were stripped, do you think the motor would spin rapidly.
Having no load?
I really don't know, never worked on a device as this. If memory serves the
OP said the motor hummed but didn't turn.
