enter image description hereI tested the fan and there is power. However the switch to the fan has no power. The light switch next to the fan switch is working. Could there be a problem between the exhaust fan and the switch to block the power?

  • Can you post a photo of the inside of the switch box please? Commented Jan 5, 2020 at 16:00
  • Can you post another photo, looking into the back of the box please? Commented Jan 5, 2020 at 18:37
  • Is the broken switch the one on the right? Commented Jan 5, 2020 at 22:24
  • More information is needed. Is this a new install or is this a previously installed unit that was functioning and now is inexplicably not functioning. Please provide as much information as possible to get an informed answer.

I have repaired dozens if not hundreds of bathroom fans, flick the fan if it doesn’t spin for at least 5 seconds it needs lubricant, most are sleeved bearings and some wd40, or 3 in 1 oil may bring it back to life , I get slammed for suggestions of wd40 but it works to free things up in oil light bearings, a few drops of 15 to 40 weight motor oil will also work but it may take longer. I have got vent fans going many times with light oil or penetrating oil and even wd40 has lasted for a year or2 but a light oil is better
