Why winter makes doors stick
Winter makes garage doors stick for several reasons at once. Metal contracts in the cold, so tracks and rollers fit tighter than they did in summer. Lubricant thickens, so hinges and rollers drag instead of rolling. Weatherstripping at the bottom of the door can freeze to the concrete floor overnight, so the door will not lift at all until that seal thaws. And an opener that was already working against a weak spring will struggle most on the coldest mornings, when the spring is at its weakest. Any one of these can make a door stick, and in a Springfield cold snap you often get two or three together. Call Springfield Garage Door Rescue at (615) 235-0324 if the door will not move, and tell us whether it is stuck shut, stuck open or stuck halfway.
The four winter causes, in order
- Frozen weatherstripping. The bottom seal freezes to the floor, so the door will not lift. This is the most common winter stick, and it often frees itself as the day warms.
- Thickened lubricant. Old grease turns stiff in the cold, so rollers and hinges drag and the opener strains.
- Contracted metal. Cold shrinks tracks and rollers slightly, which turns a small misalignment into a sticking door.
- Opener force settings. An opener set for summer may not have enough force to lift a cold, stiff door, or it may reverse because it senses extra resistance. Force settings are not a homeowner adjustment to guess at, so leave them to a pro.
Safe checks in cold weather
- Look at the bottom seal. With the door closed, check whether the weatherstripping looks frozen to the floor. If it is, wait for it to thaw rather than forcing the door.
- Clear ice and debris. Clear ice, leaves and grit from around the door bottom and the track near the floor, without putting your hands near springs or cables.
- Check the sensors. Wipe the photo-eye lenses clean, since frost and condensation can cloud them and make the door reverse.
- Listen, do not force. Try the door once. If it strains, stops or feels heavy, switch the opener off and call. Forcing a frozen door can snap a spring or burn out the opener.
For a door that sticks in other seasons too, see track repair and roller replacement. Homes in Autumn Hills often call after the first cold snap of the year.
What not to do in winter
- Do not force a frozen door. Forcing it can snap a spring, bend a track or burn out the opener motor.
- Do not pour hot water on the door. Hot water can refreeze, damage seals and make the next morning worse.
- Do not adjust springs, cables or force settings. Springs are under tension, and force settings affect safety reversal. Both need a pro.
- Do not oil a frozen track. Oil attracts grit and does not thaw a frozen seal. Wait for the thaw, then get the door checked.
When to call in winter
Call right away if the door is stuck open and will not secure, if it feels very heavy, if a spring has snapped, or if the door is crooked. Emergency service is available around the clock. Call during open hours, Mon-Fri 7AM-7PM and Sat 8AM-4PM, if the door sticks every cold morning, since that pattern usually means a spring, roller or track fault that winter is only exposing.
Frequently Asked Questions
1. Why does my Springfield door stick only on cold mornings?
Cold contracts metal, thickens lubricant and can freeze the bottom seal to the floor. A door that sticks only when it is cold usually has one of those winter causes, plus a spring or roller that was already wearing.
2. Can frozen weatherstripping break a garage door?
It can strain the opener and, if the door is forced, snap a spring or bend a track. If the seal looks frozen to the floor, wait for it to thaw rather than forcing the door.
3. Should I change my opener force settings in winter?
No, not by guessing. Force settings affect how the door reverses on contact, so they are a safety setting. If the opener struggles in winter, get it checked and let a pro adjust it.
4. Why does my door reverse in winter when nothing is in the way?
Frost or condensation on the sensor lenses, a stiff track, or extra resistance from cold lubricant can all make the opener reverse. Wipe the lenses first, and call if it keeps happening.
5. How do I stop my garage door freezing shut?
Keep the bottom seal clean and in good shape, clear ice from around the door, and get worn weatherstripping replaced before winter. A door that already sticks in fall will usually stick harder in January.
