Troubleshooting Guide
Condition
Check
- Door will not open or close.
- Check remote battery (battery is good if tip lights red when
buttons pressed).
- Check outlet where control unit is plugged in for power.
- Open control box and check if power light is on. See page 14.
- Check fuses. See Page 11.
- Check whether up / down light indicators on circuit board
light when remote buttons depressed. There will also be an
audible click when depressed.
- If you experienced a power outage at any time, reprogram
remote. See Page 10.
Power surges can also damage electronic circuit boards.
Using a surge protector is highly recommended.
- Door will not open
- Open door and / or stair manually if closed. Press remote to
open and check if door latch retracts automatically.
- Door opens but stair will not fully
unfold. (starts and stops)
- Is there a metal roof on the building? Metal roofs create dead
spots which can interfere with the remote’s signal.
- While closing, door stops short of
closing fully. (Does not go fully up into
frame).
- Check that bolts holding extra treads together at bottom of
stair are not over-tightened, as this will create resistance and
stop motor.
- While closing, door goes fully up into
frame but will not latch shut.
- Steel hangers may have been over-tightened during installa
tion, slightly bowing steel trim and not allowing latch to enter
slot. Lightly file down lower edge of slot to allow latch to
engage.
Do not file too much as this will cause door to hang
lower than trim.
