Garage Door Opener: Genie ISD1000 Excelerator (gear-drive, 1/2 hp, 2001 from Home Depot).
In May 2023 Genie kindly provided two working replacement circuit boards (CB), 36428R.S (Motor) & 36600R.S (Control).
Need motor board but not available from Genie.
Does anyone have the circuit diagram for the two CB's? Suggestions for troubleshooting.
Any one have FMEA data when CB's were designed and tested (suspect E-Caps)? What component will cause these symptoms?
Has anyone turned a axially splined chain-drive shaft (unit turned 90 degrees) to couple to the existing gear-drive? See sketch below.
Last month, New problem. Symptoms: unit runs 2-3 seconds, stops, no further unless power is reset (unplug, replug 120 vac), then unit repeats same symptoms. This started upon re-framing the rough-opening, plenty of clearance now.
Motor CB is no longer available. Genie's only available gear drive unit is 2 hp and offered that, waiting. I asked Genie to forego that 2 hp gear-drive replacement unit and send the Control CB, and help with diagnostics, i.e., which board is likely trouble, a CB circuit diagram, FMEA, etc.
Meanwhile, Lowes sold to me a discounted, returned chain drive Genie unit, model 1035. It remains in the box as an option. I prefer to replace the CB's on my gear-drive 1/2 hp unit.
