I'm sure your spouse has already cautioned you, but it never hurts to reinforce ...you be careful climbing around up there!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!
