In snow country, the most common winter problem is meltwater that refreezes under the door and bonds the bottom seal to the floor. Do not keep pressing the opener button. Clear the ice gently without cutting the seal, keep the threshold dry, and stop using a door that feels like dead weight, because a broken spring may be the cause.
1Why mountain towns are different
The Town of Truckee's tourism site lists an average of 201 inches of snowfall for the town and puts downtown at an elevation of 5,980 feet, citing the Western Regional Climate Center. That much snow means a garage door spends winter next to piles of it, with plowed snow, meltwater and freezing nights all meeting at the threshold.
The same pattern, in smaller doses, applies to any foothill or mountain town that sees a hard freeze after a wet day.
2The main problem: a door frozen to the floor
Overhead Door explains that meltwater or rain under the door can freeze overnight and stick the rubber seal to the driveway. If you then press the opener button, the opener pulls against ice. Overhead Door says not to force it, and recommends gently chipping the ice away or thawing it with a hair dryer.
A door that is stuck to the floor can strain the opener, tear the seal and put sudden load on the cables and springs. Stop, release the door by hand if you must and clear the ice first.
3What to check, and when
| When | What to look at | Why it matters |
|---|---|---|
| Before the first storm | Bottom seal; slope of the pad or driveway at the door; ice-melt supplies | A hard, cracked seal can stick; water that pools at the door will freeze |
| After a storm | Snow and ice at the threshold and along the tracks | Ice in the path can stop the door and stress the opener |
| On a freezing morning | Whether the door lifts by hand | A door that lifts easily points to the opener or seal; dead weight points to a spring |
| End of winter | Seal, rollers and hinges | Cold hardens rubber and old lubricant |
Treat the table as a starting point. Your owner's manual has the final word for your door.
4A calm routine for a stuck door
Stop pressing the button
Repeated tries do not help and can damage the opener.
Check the threshold
Look for ice stuck to the seal. Chip it away gently or thaw it with a hair dryer, taking care not to cut the seal, then correct the source of the water.
Pull the release and lift by hand
Overhead Door's quick test: if the door lifts easily by hand, the problem is likely the opener or the safety sensors. If it feels like dead weight, stop, because a broken spring is likely.
Clean old grease out of the rollers
Overhead Door notes that old grease can thicken in freezing temperatures and jam roller bearings. A technician can clean it and apply a silicone-based lubricant.
Call for help if it still will not move
Springs and cables are under high tension and are a technician's job.
5Seals and lubricant in the cold
Clopay says silicone lubricants hold their consistency through hot summers and freezing winters, and warns against oil-based sprays that attract dirt. It also says to wipe the tracks and keep lubricant off them. For the seal, Clopay says most last 2 to 3 years depending on climate and use, so a seal in a snow town may need to be replaced on the shorter side of that range. See bottom seal replacement.

Questions people ask
How do I unfreeze a garage door stuck to the floor?
Do not force the opener. Overhead Door suggests gently chipping the ice away or using a hair dryer, taking care not to cut the seal.
Can snow damage a garage door opener?
Pressing the opener repeatedly against a door frozen to the floor can strain it, so clear the ice before you run the door.
Why won't my garage door open when it is freezing?
Common causes are a seal frozen to the floor, hardened grease in the rollers or a broken spring. Pull the release and lift by hand to see which one it is.
Do I need to replace the seal after a freeze?
Only if it is cracked, torn or no longer springs back. Clopay says to replace seals in that condition, and to inspect them about every three months.
