SOURCE: Garage door only raises about two inches then stops.

Check the door springs and also remove the cover from the motor unit and check the drive gear. The door spring could be broken or the drive gear may be stripped.

The sensors only work when the door is closing.

Hey I want to know where the learn button is on merlin 230t garage door motor thanks


Press and release the green operate button to move the
door up or down. Press again to stop in the required fully
open or fully closed positions. Each time the operate button is pressed the door will stop or move in the opposite
direction.fio7c8ndqjcnbwivaodrak7uj3hwweu20kudaeajwikaaaadgbmbaaagacccaaamae4eaaayajwiaaawadgraabgahaiaadaaobeaacaaccjaaaaa4ataqaabganagaadabobaaagaa78f8dc5tazpfvnuuaaaaasuvork5cyiia

I have a Merlin 230T garage door opener and it has started to run in the opposite direction. ie; it is closed now and when I use the remote control it tries to close more


Pull the emergency release handle. Use remote to open door then close it again with the remote. Now re engage the emergency release. That should put the chain in the right position for proper operation.

Merlin 230t Door completes closing and goes straight back up again without using the remote...all adjustments have been made by a licenced door mechanic and yet it still refuses to stay down


Check for black marks on the wall or something it may be hitting . (if so the track is to tight to the wall)..... also Release the door from the opener and check it manually make sure its smooth and balanced correctly two panels up two panels down

The garage door will open and then close then open and then the light starts to flash it's a Merlin 230t


This just happened to me. The issue was that the chain that the motor moves back and forth to open/close the door needed to be tightened as the tension had become slack, so the door was hitting the ground hard when it closed and the system automatically raised the door. I closed the door by adjusting the downward travel and then tightened the chain tension by twisting the bit at the of the chain (you'll see it and can use your fingers to do this), once done, then it was a matter of adjusting the upward and downward travel knobs and testing the door to make sure the door was back to normal.

I have a Merlin 230T garage door opener which abruptly stopped working altogether. Could it be the fuse?--or any other suggestions.
