Operation LiftMaster

December 7th, 2009

One of my LiftMaster garage door openers (1/2HP, Model 1205A, MFT 1999) stopped working after 10 years.  Upon first glance, I saw white dust had accumulated in the Up/Down travel adjustment holes. Upon removing the casing, the nylon drive gears had failed (the drive gear that turns the sprocket had stripped).

This past weekend I fixed the opener in about three hours and I highly recommend the: Liftmaster Gear and Sprocket Assembly Kit Part Number 41C4220A.

I also bought Sears Craftsman Liftmaster Garage Door Opener Gear Kit – Part #41A2817 as well because my house has two LiftMaster openers.  But I found the sprocket solution to be better in this case as I could just drop it in.  I now have the extra stripped sprocket which I can use with the extra part kit to replace the stripped gear and reuse it on my second opener when and if that fails.

300 Gallon Rain Water Collector

July 9th, 2008

A summer project is complete!   Just in time as we are under water restrictions due to a drought.

Installed under my front porch is a 300 gallon rainwater collector and is modeled after my Dad’s rain barrel.  The main difference between ours is the pump is not hooked up to a pressure sensor.  Rumor has it that the pumps used do better when there is a continuous flow of water through them (even though restricted) in order to keep them cool.   We will see how each approach lasts over time.
