Auto coop doors for harsh winters

Tried to search previous forums but didn’t find much for this specifically.

I have an automatic coop door, had good reviews on Amazon. Worked great all summer. But…one snow event and some chilly weather and it’s failing to close. From what I can tell, there may be ice crystals or something forming in the tracks and the “anti-pinch” feature is encountering that resistance and then reopening, but never closing again. Quite annoying.

So, what’s your best “we have real winter here” recommendation for an automatic coop door, and are there any tips and tricks (locate on a certain side of the coop for better success, etc).

We have temps to -40 F. Snowfall is incredibly variable year to year, last year we had only a few light snowfalls. A few years ago we had 8 feet of snow over the course of the winter. Prevailing winds from northwest but storms can blow in from the north, east, south, or west. North Dakota has a mind of its own 🤷‍♀️. My current coop I can really only locate the door on the south side. I plan to move to a larger coop for next winter, and there it would be easiest to put the door on any side except for the south. I can live with a door that I might need to manage in the most extreme weather. But I mean it wasn’t even 0 yet and this one was failing.

I'm a fanboy of this product but it is on the more spendy side. The reason I like it is because it is built rugged and can feasibly be tinkered on at home.

Check out the ADOR1 Automatic Chicken Door.

I am on my third year with winters (ice storms) in Upstate New York using the same lantern battery with no issues. I would recommend having some sort of small overhang at the least to prevent drips from getting on the door and potentially freezing but my run has a roof over it so it hasn't been an issue.

I like the suggestion by Timothy to add an overhang, sort of like a roof.

I have also read that adding a light film of cooking oil might help.
