FIX/REMEDIES
Check / replace / reset main panel fuse or breaker.
Note: if it repeatedly trips, there is a short.
Check wiring from panel to control for an open circuit.
Note: there may be an in-line on/off wall switch.
Change switch position to on.
Check push plate connections to control. Check for
proper operation of push plate by using a multimeter to
check for 0 ohms when the switch is pressed, as
measured at the control inputs.
Check the motor cable plug on the control unit.
Check with a multimeter for 0 ohms, and replace with a
fuse of the same rating. Continued blowing of fuses
suggests either a short, miswiring or lastly a bad control
unit.
Check if kill is active.

arm per installation instructions.
