Coleman Mach 3 coils freezing
We tried to run our A/C for the first time this year and it would try to cool for about an hour, then the evaporator coils would be iced over and it would not cool any more. The unit is a Coleman Mach...

We have in the past had the coils ice up when run on low fan speed and high moisture.
Recently we had one unit quit. Fan had to be replaced.
Checking the vents inside it was discovered a lot of the cooled air was going right back to be cooled again due to no gasket or sealing around the intake, just pieces of fiberglass board loosely fitted. They taped it up with metal tape and no leaking back to the cooling side and early shut off, and a lot of lost cool air elsewhere.
I going over that with the thought that, because I think it contributed greatly to the icing up under slow fan speed and high humidity, since the units were designed to function under such conditions.
