Garage Door Problems and Faults

Automatic Garage Doors
Some automation systems use a ‘bottom safety edge’ either instead of or along with photocells. This is a pressure sensitive device that runs along the bottom edge of the garage door. These can sometimes be wireless and have a small battery in the sensor on the door. A failed safety edge will usually cause the same issues as problems with photocells and replacing the battery can usually fix this.
An electrically operated door needs electricity! It sounds obvious but is often worth checking that there has not been a mains power cut or that one of the fuses in the property has not blown or been tripped. A word of caution however; fuses, breakers and RCD’s are protection devices, if something has tripped or blown then there is a reason for it. One of the most common power problems we come across in garages is ‘nuisance tripping’ as a result of water or damp affecting circuits, often from old leaky roofs. If there is no obvious reason for tripped or blown fuses then you should call a qualified electrician.

Garage Door Springs

Torsion springs run across the top of the door frame and have a spindle running through them. They can ‘lose’ tension over time or fail completely which will make your garage door heavier to lift. Springs can be replaced or tension can be added to existing springs but we recommend this is done by a garage door expert.
Extension springs are usually fitted at each side of the garage door frame. If one or both of the springs fail it will make the door very difficult to lift. Extension springs can be replaced and we keep a full range of springs in stock at our warehouse in Leeds for all the major manufacturers. We can also have obsolete and obscure springs custom manufactured. It is often not too difficult to replace extension springs. If you can source the correct replacement springs and are reasonably competent at DIY then it is possibly something you can do yourself. We recommend that the springs at both sides of the garage are replaced at the same time to ensure the door balances correctly. Please be aware, however, that garage door springs can be under a lot of tension and can cause serious injury if they are not fitted correctly, so if you are in any doubt then call an expert.
Hi, Supramatic e2 is stuck on H partially open mode. Can you please advise how I can return it to normal setting mode as it won’t open with the remote control. Thank you.
Hi Michael,
Are you sure it is not a fault? Does the door open fully using the buttons on the front of the head unit? If it does and it is just that the hand transmitters are coded into the partial open program then you would need to delete all the hand transmiiters from the operator and recode your hand transmitters into the fully opening program on the operator.
You can download a PDF of the full instructions from the Hormann website that detail how you can do this at the link below.
