Replace Roof AC units - 1992 WB40

[Stephen Birtles]

One thing we found with the Brisk air is to regularly exercise the fan
or it will seize on the bearing and there is no way to free them up
without replacing the fan motor
We replaced 2 that were only 2 years old they were covered under
warranty but it is a pain in the butt
