The last few times we were camping, I noticed our bathroom fan would sometimes not come on.
A couple times I noticed if I closed and reopened the lid it would work. I started doing some research and found it’s common for the plunger switch to go bad. I was able to find a part breakdown and ordered the switch from Amazon. https://amzn.to/3v8mnsO
It would probably take about 15-30 minutes do it yourself. Plus it saves the hassle of replacing the $280 fan.by
