I have an Overhead 1055 garage door opener that suddenly died. Before going
completely dead the motor grunted a couple of times. Do the motors
typically fail like that? It is any use trying to replace the motor? If I
replace it, should I stick with chain drive or try another style, e.g.
what's considered the best today?
If the motor bearings went, it could do the grunt thing a couple of times
and then freeze up. Pull the motor out and see if it will run with no load.
If it runs with no load it may stall under load so don't get excited yet.
See if the mechanism is movable or if the good motor is trying to turn a
frozen drive system.
Chances are you can lube the drive mechanism but not the sealed bearing
motor. If it is the motor, check with a place like Grainger for a
replacement. The cost will determine if it is worth replacing or by a whole
Mine did the same thing, right after a lightning storm. I looked up the part
number on the Sears web site and they gave me different part number. A
couple of garage door folks said the board was available only from Sears. I
get nervous when parts become really hard to get when the product is only 5
years old. I went to Lowes and bought a Chamberlain and changed the head out
in about an hour. Now I have all new parts that match and work together.
I did take the cover off the unit and immediately saw "Motor Starting
Capacitor"...hitting the switch at times makes a clicking sound, I think
coming from this device, and other times not...could this capacitor be the
First off, forgive me for not knowing what a 1055 is. Does this
operator have a name, or just a numeric designation (legacy, python,
overdrive, (maybe a 1000 ss) etc...)? How old is the unit?
Motors don't usually just Die.
If the units designation is numeric, change the starting capacitor
first. That could easily make one "grunt" and then die.
If it's got a "name", we'll need to know what it is before any
speculation is done.
As far as a replacement goes...
You can't really go wrong with a chain drive. The screw drive
"excellerator/overdrive" is kind of "iffy" in my book (a normal screw
drive is fine, but messy) and you do not want a chain pusher
