When Genie invented the Excelerator garage door opener, the company advertised it as the fastest on the market. But that fast speed can be somewhat of a mixed blessing, since the high speed often causes premature wear and tear on the door. If you own an Excelerator garage door opener, you can avoid this problem by resetting the speed on the unit.
Things You'll Need
Diagonal wire cutters
Unplug the Genie Excelerator garage door opener. Flip down the light cover and remove the bulbs.
Unscrew the four screws that secure the motor cover. These screws are located at the bottom of the garage door opener. Swing the motor cover down to access the electronics of the Excelerator garage door opener.
Look at the resistor board and find the resistor with the "Speed Option" label. Use a pair of diagonal cutters to cut the wire running to the resistor, then bend the resistor so that the ends do not touch one another. This disconnects the part of the circuit board that makes the Excelerator so fast and forces it to run at normal speed.
Lift the motor cover up over the two posts labeled P1 and P2. Be sure that the P1 and P2 posts go through the holes in the cover. Tuck the cut wires in so that they do not stick out past the cover, then insert the screws back into the cover, reinstall the bulbs and close the light cover.
