BUTTON OR TRANSMITTER
1. Have you disengaged ali door locks? Review Step 8, Page 14
2. Does the opener have electric power? Plug a lamp into the outlet If it
doesn't light, check fuse box or circuit breaker (Some outlets are con­
trolled by a wall switch).
3. Repeated operation may have tripped the overload protector in the motor.
Wait 15 minutes. Try again.
4. Is there a build-up of ice or snow under door? Door may be frozen to
ground. Remove any obstruction

minals together with a jumper wire, if opener runs, check for a faulty wire
connection at wall push button or a short under staples.

there is a short or broken wire between push button and opener.
