To Next PageTo Next PageWhat to do if my Chamberlain LA412 shows Absolute Position Encoder Error?
If your Chamberlain Gate Opener displays an Absolute Position Encoder Error, indicating it's not getting position information from the encoder, check the APE assembly and wiring connections. If the problem continues, you may need to replace the APE assembly.
What causes 'Close input (EYE/EDGE) communication fault from other operator' on my Chamberlain Gate Opener?
If your Chamberlain Gate Opener shows a close input (EYE/EDGE) communication fault from another operator, check the inputs and communication method between the operators, whether it's a wired bus or radio. Ensure the operator is powered. You might need to erase the wireless communication and reprogram the two operators.
What does Exit Loop Error mean on my Chamberlain LA412?
If your Chamberlain Gate Opener displays an Exit Loop Error, it indicates a failure or missing loop. This applies only to LiftMaster Plug-in Loop Detectors. Check the loop wiring throughout the connection for shorts or open connections. There may be a short in the loop, or an open connection.
Why does my Chamberlain Gate Opener say 'CLOSE EYE/INTERRUPT held more than 3 minutes'?
If your Chamberlain Gate Opener indicates that the CLOSE EYE/INTERRUPT has been held for more than 3 minutes, check the wired input on the main control board for proper alignment and any obstructions.
Why does my Chamberlain Gate Opener say 'CLOSE EYE/INTERRUPT held more than 3 minutes' on expansion board?
If your Chamberlain Gate Opener indicates that the CLOSE EYE/INTERRUPT has been held for more than 3 minutes, check the wired input on the expansion board for proper alignment and any obstructions.
What to do if Linear Drive Disengaged (Arm 1) on my Chamberlain LA412?
If the Linear Drive is disengaged on Arm 1 of your Chamberlain Gate Opener, disengage and then re-engage the arm. Also, check the wiring and connections to ensure they are secure.
