Why do openers struggle in a Minneapolis winter?
Cold is hard on every part of an opener. Grease thickens, belts and chains stiffen and the motor has to work harder to start the door. Ice can hold the bottom seal to the floor, so the opener pulls against a frozen door and may stop or reverse. Common winter complaints include:
- A door that starts slowly, groans or stops partway.
- A remote that works only from close up, because cold drains batteries faster.
- Safety sensors that blink or refuse to close the door when frost, snow or a blocked lens interrupts the beam.
- Travel limits that seem to drift as the seals and tracks change in the cold.
An unheated detached garage is rougher on the opener than an attached garage. Even so, a heavy door, a weak spring or stiff rollers can show up as an opener problem long before the motor itself is at fault.
