1.The operator doesn’t operate from either the Door Control or the remote control:
•Does the operator have electric power? Plug a lamp into the outlet. If it doesn’t light, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)
•Is there a
•The door spring may be broken. Have it replaced (see page 3 for reference).
2.Operator operates from the remote, but not from the Single Button Control Station:
•Are the wiring connections correct? Review Installation Step 5.
3.The door operates from the Single Button Control Station, but not from the remote control:
•Program the operator to match the remote control code. (Refer to instructions on the motor unit panel.) Repeat with all Remotes.
4.The remote control has short range:•Check to be sure the antenna on the side or back panel of operator extends fully downward.
•Some installations may have shorter range due to a metal door, foil backed insulation, or metal siding.
5.The door opens and closes by itself:•Be sure that all remote control push buttons are off.
•Remove the bell wire from the door control terminals and operate from the remote only. If this solves the problem, the single button control station is faulty (replace), or there is an intermittent short on the wire between the control console and the motor unit.
•Clear memory and
•Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.
7.The door opens but won't close:•Check cable tension monitor (see installation step 4).
•Check the safety reversing sensor. See Installation Step 9.
•See Adjustment Step 2. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
8.The door reverses for no apparent reason:•Check cable tension monitor (see installation step 4).
•Is something obstructing the door? Pull the emergency release handle. Operate the door manually. If it is unbalanced or binding, call a trained door systems technician.
•Clear any ice or snow from the floor area where the door closes.
•Review Adjustment Step 2.
Repeat safety reverse test after adjustments.
9.The door reverses for no apparent reason:•Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See Installation Step 9.
10.The operator strains to operate door:•The door may be out of balance or the springs may be broken. Close the door and use the emergency release handle to disconnect the door. Open and close the door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, disconnect the operator and call a trained door systems technician.
11.The operator motor hums briefly, then won’t work:•The door springs may be broken. See above.
