The homeowner got a GREAT DEAL on two of these openers – only $89 after rebate from Menards! I replaced one existing opener that wouldn’t work, and ran a new outlet to install the second.  In addition, one of the overhead doors was all but frozen in place.  I was able to loosen the track a bit, install a couple extension springs, and lubricate the existing wheels to allow the door to raise freely.  This job was completed in Dec. 2010.
