Cold mornings expose every weak point in a garage door system. Here are the 6 most common cold-weather culprits — and what to try first.
The 6 most common cold-weather causes
- Weather seal contracted hard against the floor — door reverses thinking it hit something.
- Photo-eye sensors frosted, foggy, or knocked out of alignment by snow buildup.
- Hardened lithium grease in tracks creating extra resistance.
- Opener force setting set for warm weather, now too sensitive in the cold.
- Battery in keypad or remote dying faster in sub-freezing temps.
- Cold-shortened spring nearing end of life — the cold is just the trigger.
Try these in order before calling
- Wipe both photo-eye lenses with a soft dry cloth.
- Make sure both sensor LEDs are solid (not blinking).
- Inspect the weather seal — if it's frozen flat, gently lift the door and pour warm (not boiling) water along it.
- Push the door manually with the opener disengaged — if it's heavy or jerky, that's a spring issue, not an opener issue. Stop and call.
Frequently Asked Questions

Why won't my garage door close when it's cold outside?
The four most common cold-weather causes in Evansville are: contracted weather seal binding on the floor, frosted-over photo-eye sensors, hardened grease in the tracks, and a sluggish opener that needs a force-setting adjustment.

Should I spray WD-40 on my garage door in winter?
No. WD-40 is a degreaser — it strips lubricant. Use white lithium grease on metal-on-metal contact (rollers, hinges, springs) and silicone spray on the weather seal to keep it pliable.
