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.

To reconnect the door to the MasterCraft opener (model 046-0266-0) after using the emergency rope, flip the trolley release lever up and raise or lower the door. This will re-engage the opener with the door.

If the wall opener buttons on a MasterCraft 046-0266-0 do not work after attempting to reset by unplugging, possible issues include:
1. No power at the AC outlet — check the outlet by plugging in a lamp. 2. Wall console wiring issue — check the wiring at both the wall console and the opener terminals. 3. Wall console wire shorted — inspect the wires for any shorts. 4. Wall console is locked — unlock it if it's in lock mode.
These checks should help identify and resolve the issue.

When I open my Mastercraft garage door opener, the motor/drive makes an unusual noise for a short while part way through the travel. After the door is open, the motor whines for a short while. Then an "H" error code is displayed. I have reprogrammed the opener for the open and close limits.

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.
