My 17-year-old Sears 1/2 HP chain-driven garage door opener has finally
given up the ghost. The motor runs but the plastic gear on the shaft
that meets the motor's worm gear has shredded itself. I think that
happened because the chain had become a bit loose and got caught in a
corner of its rail and caused the gear to become bound.

I called Sears to see about a replacement and they sell the entire
shaft and gear assembly for something like $35 plus shipping. However
removing the old shaft assembly doesn't look that simple and there are
more plastic gears attached to the bottom of the shaft that are
adjustments for the up/down distances. I suppose it could be done but
considering the age of the entire opener I am leaning towards buying a
new system.

Lowe's has a Chambelain 3/4 HP chain-driven opener for $157. After
speaking to the associate I realized everything must be changed,
including the chain and its rail system. Home Depot has a Genie 1/2 HP
screw-driven opener for $161.

My home repair skills are moderate and I am certainly no advanced
person, but I am an electronic technician and do have a wide assortment
of hand tools. I think I can do the installation although I don't know
how long it would take me.

What is your recommendation regarding the choices of openers and what
caveats should I be aware of if I choose to tackle this job myself?
Thanks for your thoughts.

Sears and others sometimes has a low cost install like 50 to 75
bucks, in my opinion its well worth the $$. A crew of 2 guys, amazing
how fast its in:)

The new opener will have sensors to reverse if anything walks in door
area, like a pet. Optical

I ike belt drive myself, very quiet:) Do get a touch pad for outside
mounting, its REALLY convenient. Indoor door open indicators are nice
too:)

They have openers that also turn on indoor lights so you dont enter a
dark home.

All this safety and convenience is pretty cheap.

If you decide to DIY install you will need a helper to hold stuff

Do inspect your door, lube etc, check and install safety cables if
needed.Rollers do wear, That opener may have been working really hard
sometimes. Bearings and rollers wear out and may of never been lubed
since they were installed:(

Your old door probably needs attention too..... Might as well do this
together!

some openers come with battery backup options, if that matters to you.

Not a garage door, but a sheet vinyl floor. And 35 years ago, but the
big hardware store on Flatbush Avenue north of Prospect Park in
Brooklyn wanted 10 dollars to install the kitchen floor. Even though
I had little money, that seemed cheap even 35 years ago.

I'd taken everything out of the kitchen.

They delivered also for that price. A big floor that had to be folded
to go in the elevator. The room had 6 corners. The guy held it up,
looked at the room, and cut it in less than 2 minutes, and it was
between a quarter inch and 3 inches bigger than the floor all around.
Then he did a second cut that fit just under the baseboard, in another
two minutes. He was in and out in about 10 minutes. It would have
taken me 5 hours.

Allowing ten minutes travel time, they were actually taking in 30
dollars an hour, 20 minutes travel time gives 20 dollars an hour, so
they were probalby still making a profit.

It would be a lot less work to fix the old one. Just watch things very
carefully when you take out the old part so the new one goes in the same.
