Windows hard to open

Maybe he fluffed?

I was just wondering, why if it's that cold out are you trying to open the window?

Thanks everyone, I have lubed the sides of the frames, as they were tending to bind,after I passed the stopped part.
It seems to be something in the center of the window,, where the upper and lower section meet when down. After getting past this part, the windows go on up. I'll try some silicone.
When it gets above zero here, I think I will remove one window completely.
Maybe I can then see what is happening. Replacement windows are pretty pricey.

My unit is level.

deleted, double post!!!!

What you are describing (beside being a lube issue) can be caused by improper leveling. If your frame is slightly tweaked it can cause windows and even door frames to be off and thus hard to open or close.

Try re leveling and don't over tighten your stabilizing jacks..

If it were me I would try some silicone lubricant, NOT anything with petroleum in it, which will attack rubber. Armorall, which last time I checked the MSDS sheet does not have any.

Spray some drylube on the seal you should be fine

I had good luck •sparingly• spraying silicone on the rails while the window is open.
