I went up into the high attic(the house has two attics that are separated) to see if I could get the gable fan working. It is seized up and the oil trick did not work. I installed that fan in 2018 and it quit working a couple of years ago.
It is not easy to reach, with climbing and scooting along the rafters. I am sore already!
I ordered a replacement that will be here about Thursday. Hopefully this one will last longer. I plan on putting some electric motor oil on the shaft of the new one and applying oil at the start of each summer. Hopefully that will help it last longer.
I have to work in the attic early in the morning before the temps get to 150F up there!
