bathroom exhaust fan doesn't work
The fan was the problem. I measured voltage at the fan and it was 125. Experience has told me to look for the sample explanation first. I started with the wall switch. Wrong. I should have went to the fan first. Replacement was simple. I didn't have to remove the casing, only the fan which was a Nutone. I found it at Home Depot...Lowes did not have it.

Next problem I have I will think about it more before I actually do anything. Perhaps my advanced age (77) has blurred my thought processes.
