Dashed arrows identify wiring paths between boards and terminal groups. | ⚠ WARNING | |---| | To reduce the risk of INJURY or DEATH: | | • DISCONNECT power and battery BEFORE installing or servicing operator. | | • Replace ONLY with fuse of same type and rating. | | • To be compliant with UL325 and industry safety guidelines, qualified monitored external entrapment protection devices such as photoelectric sensors or edge sensors are required to be installed with this operator at each entrapment zone. ONLY LiftMaster approved entrapment protection devices (refer to the accessory page of manual). | | • See owner's / installer operating maintenance and required safety testing. | ### Diagnostic Codes **TO VIEW THE CODES:** Press and hold STOP... …then press and hold CLOSE... …then press and hold OPEN until “Er” shows. The operator will show the code sequence number followed by the code number: **First code shown is the most recent code** (example: “01”). The display will show two “01” and going up to code “20”. **TO SCROLL THE SAVED CODES:** Press the OPEN button to cycle to the most recent code (“01”). Press the CLOSE button to cycle to the oldest code (up to “20”). ### Code Color Key | Color | Meaning | |---|---| | Yellow | LiftMaster System | | Orange | Installed System | | Green | Informational | | Dark red | External Entrapment Protection | | Black | Inherent Entrapment Protection | | CODE | MEANING | SOLUTION | |---:|---|---| | 31 | Main control board has experienced an internal failure. | Disconnect all power, wait 15 seconds, then reconnect power (board). If issue continues, replace main control board. | | 32 | Linear Drive Disengaged (Arm 1) | Disengage or re-engage arm. Check wiring and connections. | | 33 | Linear Drive Disengaged (Arm 2) | Disengage or re-engage arm.
