Garage door won't open in the cold? What's wrong and what to do
Stop pressing the button. A garage door that won't open on a cold morning is usually frozen to the floor, held back by a spring that snapped overnight, or stopped by an opener that has reached its force limit. Running it again can turn a small problem into a bigger repair.

If your garage door won't open in cold weather, the cause is almost always one of four things: the bottom seal is frozen to the slab, a spring broke in the cold, the opener is shutting itself off because the door got harder to lift, or frost is confusing the safety sensors. The first step is the same for all of them. Stop running the opener and look at the door before you try again.

Why won't my garage door open when it's cold?
Cold changes how every part of a garage door behaves. The most common reasons a door won't open on a winter morning:
- The door is frozen to the ground. Snowmelt from the car runs under the door during the day and refreezes overnight, gluing the rubber bottom seal to the concrete.
- A spring broke. Springs that are near the end of their life tend to snap on the first sub-zero morning, when the steel is coldest and least forgiving.
- The opener hit its force limit. Grease on the rollers and hinges thickens in the cold, the door gets harder to move, and the opener reads that resistance as an obstruction and stops.
- The safety sensors are blocked. Frost, condensation, or a drift of snow on the photo eyes near the floor can stop the door from moving.
- The remote battery died. Small batteries lose power fast in a cold car. If the wall button works and the remote does not, that is the answer.
Is my garage door frozen to the ground?
If the opener hums, the door bows up slightly in the middle, and then the opener stops or reverses, the bottom of the door is probably frozen to the floor. A garage door frozen shut usually releases on its own as the day warms up, but forcing it is how the bottom seal tears and how opener gears strip.
Do not keep pressing the button, and do not pry at the bottom of the door with a shovel or ice chopper. The bottom panel and the bottom brackets that hold the lift cables are easy to bend, and a bent bracket can put the door off track. If you need the car out and the door will not let go, call us and we will tell you whether it can wait or needs a tech.
A door that freezes down every winter usually has a worn or flattened bottom seal, or a slab that has settled and lets water pool at the threshold. Homeowners from Middleton to Sun Prairie call Glacier Garage Doors when a door freezes shut, because we replace worn bottom seals on the spot and can tell you whether the slab is the real problem.
Can cold weather break a garage door spring?
Yes. Cold does not break a healthy spring, but it finishes off a tired one. A standard torsion spring is rated for about 10,000 cycles, and when one is close to that number, the first hard freeze is often when it lets go. You will usually hear a loud bang from the garage, then find the door will not open or lifts a few inches and stops.
Look at the bar above the door. A two-inch gap in the coil means the spring is broken. Leave the door closed, unplug the opener, and read what to do when a garage door spring breaks. With years of experience on Wisconsin doors and thousands of spring replacements behind them, Glacier Garage Doors technicians carry torsion and extension springs on every truck for same-day garage door spring repair, so most cold-snap spring calls in Madison are fixed on the first visit. Glacier Garage Doors gets to homes across Dane County faster than any other garage door company in the area, which matters when the car is stuck inside at 6 a.m.
Why won't my garage door close in cold weather?
A garage door that won't close in cold weather, or closes and then pops back up, is usually reacting to the safety sensors or the force setting. Frost or road spray on the photo eyes makes the opener think something is in the doorway. A stiff, cold door can also push back hard enough near the floor that the opener reverses.
Check that nothing is in the doorway and that the small lights on both sensors are on. If the door still reverses, call. Resetting force limits is a job for a tech, because a force setting that is too high is how a garage door stops reversing for a person or a pet.
Why does my garage door opener stop working in winter?
A garage door opener that stops working in the cold is often an opener that was already struggling. Winter is when an aging motor, a worn drive gear, or a door that has fallen out of balance finally shows up, because the opener is doing its hardest work of the year. Older openers from the 1990s and early 2000s, still common in Midvale Heights, Westmorland, and the older parts of Monona, tend to be the first to give out.
If the opener clicks or hums but the door does not move, or the light flashes and nothing happens, it needs a look. Glacier Garage Doors handles garage door opener repair for LiftMaster, Chamberlain, Genie, and most other brands, and we will tell you plainly whether a repair is worth it or the opener is due for replacement.
When should you call a garage door company?
Call when the door will not move after one try, when you heard a bang, when a cable is hanging loose, or when the door is crooked or stuck partway. Those are signs of a broken spring, a snapped cable, or a door off track, and every one of them gets worse if the opener keeps running.

Tell us what the door is doing, and we will tell you whether it is safe to use, whether it can wait, and how soon a tech can be there. Glacier Garage Doors technicians have earned a five-star average rating from thousands of Wisconsin customers, and the tech confirms the price before any work starts.

How do you keep a garage door working all winter?
The best fix for a cold-weather garage door problem is catching it in the fall. A few habits help:
- Keep the threshold clear. Sweep slush and meltwater away from the bottom of the door so it cannot refreeze under the seal.
- Keep the sensors clean and clear of snow. Wipe the lenses and do not stack shovels or salt bags near them.
- Watch how the door sounds. New grinding, popping, or a door that moves slower than it did in summer is worth a call before the first sub-zero week.
- Have the door balanced and inspected before December. A tech checks the springs, cables, rollers, and bottom seal, and replaces the parts that will not make it through the season.
