replace an existing chain drive garage door opener
I have a pair of Craftsman garage door openers that are about 25 years old. I have replaced the wireless opener on one and the other now needs the same plus some yet undiagnosed repairs/adjustments.
Looking at repair and replacement of the remote wireless opener I started looking a new opener setups at Lowes and Home Depot. It appears I can replace the whole mechanical and electronics with upgrades for only two to three times the cost of just buying and installing a new wireless open/close control.
Thinking along those lines I believe if I buy a similar power (fractional HP) and a chain drive I should be able to reuse all the infrastructure of my old opener. I think I can simply remove the old motor and chain, and install the new motor and chain (adjusting, cutting the chain to the needed length). I will not need to install the angle iron support and pull rod. Here I note the current Craftsman chain connects to a slider that connects to the chain/door and it glides along the "pull rod" (here I mean the iron/steel that runs from the motor to the wall in which the door operates. If that is proprietary the new door may require I use its provided "pull rod".
I welcome any ideas on retrofitting a new opener in an existing system.
Home Depot has a Genie Chain Max 1000 for $120, marked down from $179 as I recall. It comes with two remote controllers and a wall mounted keypad opener, an upgrade from the existing door. I wouldn't be surprised to learn Genie make some of the Craftsman openers.
