FROM EITHER WALL PUSH
SUTTON OR TRANSMITTER
1. Have you disengaged all door locks? Review Step 8, Page 14
2. Does the opener have electric power? Plug a lamp into the outleL 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
5. Remove bellwire from opener terminal& Touch red and white screw ter-
minals together with a jumper wire If opener runs, check for a faulty wire
connection at wall push button or a short under staples.
OPENER OPERATES FROM
TRANSMITTER BUT NOT FROM
WALL PUSH BUTTON
1. Is wall push button lit? If not, refer to No. 5 above and follow same
procedure.

DOOR OPERATES FROM
WALL PUSH BUTTON BUT NOT
FROM THE TRANSMITTER
1 Does the battery test light glow when transmitter push button is pressed?
If not, replace the battery (Page 5 tells you how.)
2 If you have two transmitters and only one operates, review code setting
procedures on Page 1 9 Receiver and ALL transmitters must be set to
same code_
& Is transmitter(s) operating additional remote control devices? See code
setting procedures on Page 1 9
4. Did you press transmitter button designated to operate garage door
opener?
5 Re-program receiver(s) and ALL transmitters, Try setting ALL the code
switches in plus, center or minus positions. If transmitter(s) works, you
can try a random code switch setting again, if you desire.
TRANSMITTER HAS
SHORT RANGE
1_ Check battery test light If the light is out, change the battery(Page 5 tells
you how).
2. Change the location of transmitter in the car.
3 A metal garage door, foil-backed insulation or metal siding will reduce
transmission range.
4. Check to be sure the antenna on the back panel of the opener extends
fully downward.
