The next thing you need to understand is that any Merlin garage door opener is designed to assist a well maintained and balanced door. This is actually quite easy to determine but it is important to be honest with yourself when doing this test.Does the door open and close without using excessive energy or force. If you are not sure ask a neighbour or friend to try and get their opinion. The door should not spring up to quickly in opening – nor should it suddenly drop at the end of closing.

Why all this testing? Simple – If you install any garage door motor (regardless of brand or size) onto a poorly setup or maintained door you will shorten the life of your opener and almost certainly void any warranty. The first step is to adjust your door if required until you have  a door that opens and closes manually with a minimum of fuss. The Merlin garage door opener is a convenience and security option – do not rely on it to drive a dodgy door.
