Only the remote fails
- Lock mode: Chamberlain says the wall control light flashes and remotes won't work. On lock-button models, hold the button for 2 seconds.
- Battery: Chamberlain says to check it's installed correctly, or replace it.
- Range: move closer to the opener. Chamberlain also mentions interference from LED bulbs.
- Pairing: the remote may need programming again, and it has to be compatible with your opener.
Both the wall button and the remote fail
We suggest starting with power: check whether the opener's light works and whether it's plugged in, and check the breaker for that circuit. If power is fine, we recommend a technician to check the wiring and controls.
If you're stuck outside
Chamberlain suggests trying your other controls, such as a remote, keypad or app. It also says an Outside Trolley Release, if one is already installed, lets you release the door from outside.
Stop and call if the door moves oddly
If the door feels heavy or needs two hands to lift, DASMA says it's probably out of balance and that you could get hurt fixing it yourself. We give no spring steps. CPSC says that if the door doesn't reverse when it hits a 2x4 on the floor, disengage the opener until it's adjusted or repaired.
