Questions and answers
When I try to program a handheld remote, I get the “P” message but no beep sound and **** unable to program the remote.
Can you tell me what I should buy to be able to opener my garage door while I am away from home?
Wall console is showing a flashing triangle in the upper right hand corner with what appears to be an exclamation mark. Garage door will only go up in nominal increments and then slams down!!??
A flashing triangle with an exclamation mark on the MasterCraft wall console indicates a safety issue or obstruction. The garage door going up in increments before slamming down is likely caused by weak or broken springs or an unbalanced door. This condition can make the opener struggle to lift the door and may cause it to fall rapidly.
