1. The garage door opener cannot be operated neither from the door control panel nor from the remote control:
Does the door opener have power? Insert a light into the socket. If the light does not come on, check the fuse box or short circuit. Is there ice or snow under the door? The pit was frozen to the ground. Clear obstacles. The garage door spring may have broken. Please replace it by after-sales personnel.
2. The door opener can be operated from the remote control but not from the door control panel:
Is the door control panel button lit? If it does not light up, remove the bell wire from the door opener terminal. Short the red and white terminals with one wire touching both terminals at the same time. If the door opener is running, check the door control board for wiring errors, shorts under the staples, or broken wires. So the wiring is all good? Read the installation instructions again.
3. The door opener can be operated by the door control panel but not by the remote control: replace the battery if necessary. If you have two or more remote controls, and one more is in use, repeat the routine detailed in the "Programming the Door Operator and Remote Control" section. Is the door button flashing? The locking feature on the door opener is now enabled. If you have more than one multi-function door control panel, press and hold the lock button for 2 seconds. The gate button will stop flashing.
4. Insufficient range of remote control: Have batteries been installed?
