A broken spring can make the garage door extremely heavy and difficult to control. Avoid forcing the door or repeatedly operating the opener. Contact a garage door professional to inspect the spring and counterbalance system.

The cause may involve the opener, spring system, trolley, disconnect mechanism, cables or another mechanical component. If the door feels unusually heavy or a spring appears broken, stop operating it and request service.

Safety sensor alignment, obstructions, travel settings or mechanical resistance may cause a door to reverse instead of closing normally. The system should be inspected if the problem continues.

There is no single schedule that fits every door because usage varies. Homeowners should regularly watch and listen for changes in operation and arrange service when components show wear, movement becomes irregular or the door develops recurring problems.

An isolated spring, roller, cable or opener problem may be repairable. Replacement becomes more worth considering when the door has significant damage, widespread wear, repeated breakdowns, poor insulation or no longer meets the homeowner's needs.

Insulation can be worth considering for attached or heated garages, particularly in a climate with Edmonton's cold winters and major temperature swings. The right door depends on how the garage is used.

Cold temperatures can expose existing wear, affect seals and make mechanical problems more noticeable. A door that starts binding, moving unevenly or behaving differently in cold weather should be inspected.

Stop operating the door. Repeated movement can cause additional damage to rollers, tracks, cables or panels. Have the system inspected before using the door again.
