Had a new one this morning. My garage door froze solidly to the floor. Went out to get the car ready for my wife and door would not go up. Finally freed it with salt and cycling the opener enough. Left it up and added more salt. In a little while I’ll go scrape it clear. I’ve had a little icing before, but never anything this solid. My apron is pretty flat and between melt and drizzle had plenty of water lying there to freeze it in.
