Roof-Mount A/C Unit Schematic
I accidentally hit the cool setting tonight and hear a thump, thump zzzzz, coming out of the A/C fan. To me it sounds like something worked it's way into the A/C unit.
I work the fan on/off a couple of times and the thump, thump turns to scrape, scrape. If it was a rodent, we've given it a haircut - #3 buzz to be exact. But no smell.
I want to jump on the roof tomorrow and pull the A/C cover only I want to have a roadmap before I get bold. I want to know where the fan is in advance.
Anyone have an IPB of the roof A/C unit, showing the location of the fan?
