CODE MEANING SOLUTION
31 * Control board error Remove power for 15 seconds. If code continues,
replace control board.
34 Absolute Position Issue
Check the operator cable connections, then reprogram
the limits.
35 Max-Run-Time Exceeded Check for an obstruction, then reprogram the limits.
36 Product ID Error Was the control board just replaced? If so, erase limits,
enter limit setup mode and set limits. If not, disconnect
all power, wait 15 seconds, then reconnect power
before changing product ID harness.
37
38 * Hard Stop Limit may be set too tightly against a hard stop
(re-adjust limit). Operator may be at end of travel
(re-adjust mounting).
40 Battery overvoltage Possible short of the battery charge harness. Check
harness. Make sure you do NOT have a 12V battery
on a 24V system.
41 Battery overcurrent
42 No battery at boot up Check battery connections. Replace batteries if
depleted to less than 10V on 12V system or 20V on
24V system.
43 Failure or missing exit loop (SHORT or OPEN - LiftMaster Plug-in Loop Detector
only) Check loop wiring throughout connection. May
be a short in the loop, or an open connection in the loop.
44 Failure or missing shadow loop
45 Failure or missing interrupt loop
46 Low batteries in wireless edge Replace batteries
53 Input voltage too low Review power supply and wiring. If rebooting,
wait for 15 seconds then reconnect power.
60 No external entrapment protection
devices installed
Install at least one entrapment protection device (and
ensure all entrapment zones are protected).
61 CLOSE EYE/INTERRUPT (main board) Input held > 3 minutes. Check input on main board,
check for alignment or obstruction.
62 CLOSE EDGE (main board)
63 OPEN EYE/EDGE (main board)
64 CLOSE Edge Input held > 3 minutes. Check input on main board;
check for alignment or obstruction.
65 CLOSE EYE/EDGE
66 OPEN EYE/EDGE
67 Wireless edge input stuck on Check input for wiring issue or obstruction.
68 Wireless edge lost signal Check batteries, reposition edge receiver for clearer
path to operator antenna.
69 * Wireless edge triggered Remove obstruction, check inputs and wiring.
70 * CLOSE EYE/INTERRUPT reversal,
preventing close, or resetting TTC
IF an obstruction occurred, no action required.
If an obstruction did NOT occur, check
alignment, inputs, and wiring.
71 * CLOSE EDGE triggered reversal,
preventing close, or cancelling TTC
72 * OPEN EYE/EDGE reversal or
preventing opening
73 * CLOSE EYE/INTERRUPT reversal,
preventing close, or resetting TTC
(expansion board)
74 * CLOSE EYE/EDGE reversal and
preventing close or cancelling TTC
(expansion board)
75 * OPEN EYE/EDGE reversal or
preventing opening (expansion board)
80 Close input (EYE/EDGE) fault
(Secondary operator)
Check the connections between the main board and
the secondary operator.
81 Open input (EYE/EDGE) fault
(Secondary Operator)
82 Close input (EYE/EDGE) fault
(expansion board)
Check the connections between the main board and
the expansion board.
83 Open input (EYE/EDGE) fault
(expansion board)
91 Force reversal Check for obstruction. If no obstruction, check that the
operator arm is engaged and free to move. Check
actuator's wiring. Refer to Limit and Force Adjustment
section, and Obstruction Test sections in owner’s
manual.
93 Force reversal (RPM)
99 Normal Operation No action required
* Codes marked with an asterisk are displayed in real time (as the condition occurs) and will not
be saved in memory.
Unplug product ID harness then plug back in.
Disconnect all power, wait 15 seconds, then reconnect
power before replacing product ID harness.
Product ID Failure
47 Battery shorted Check battery harness for short to chassis.
54 Wireless Second Operator
Communication Error
Check the second operator for power. If OFF, restore
power and try to run the system. If powered, deactivate
the wireless feature and then re-learn the second
operator.
50 Run-Distance Error Gate unbalance detected. Make sure the gate is installed
on a level surface and not on an excessive grade.
