To fix a Merlin MT60P door that lowers to the floor but immediately goes back up, you need to reset the DOWN (close) limit:

1. Press and hold the black button until the yellow light flashes slowly, then release.
2. Use the black button to move the door up and the orange button to move it down.
3. Adjust the door to the correct DOWN position so it fully closes without excess pressure (rail should not bow, chain should not sag).
4. Press the transmitter or door control to set the DOWN limit.
5. Test the door by opening and closing it with the transmitter.

This should stop the door from reversing when it reaches the floor.

Remote opens & closes door inside garage but doesn't open door from outside.

The issue with the Merlin MT60P remote not opening the garage door from outside could be due to one or more of the following:

1. The opener has not learned the remote code – The remote must be programmed into the opener using the orange “learn” button.
2. The remote battery is low or dead – If the transmission range decreases, the battery should be replaced.
3. The remote code was erased – If all transmitter codes were erased, the remote must be reprogrammed.
4. Weather-related changes – Weather conditions may affect door operation, requiring limit and force re-adjustments.

Reprogram the remote and check the battery to resolve the issue.
