Is my radon fan working?

HOW DO YOU KNOW WHEN IT’S TIME TO REPLACE YOUR RADON FAN?

The first clue you should replace your radon fan is excessive noise. If your radon fan sounds like loud, it might be time for a new one.

Another sign that you need to replace your radon fan? Your old one stops working! You can tell that your radon fan is no longer operating when your system’s manometer is level at zero.

However, don’t call your mitigator quite yet. There are several reasons your manometer or alarm might indicate a problem, so here are a few things to consider before setting up a fan replacement:

  1. Is the fan plugged in?
  2. Did you lose power?
  3. Is your radon fan wired to a breaker that tripped?
  4. Have you checked your GFCI outlet?
  5. Have you checked if your switch if on or off?
  6. Is the small, clear tube that goes from the U-tube to the radon vent pipe still inserted in the vent pipe?
  7. Is it unusually cold outside? Extreme Midwest winters can lead your system to freeze. If it’s -20°F and your system isn’t working, don’t panic. We recommend waiting for things to warm up a bit before taking action.

If you’ve checked all of the above and haven’t found the source of your problem, it’s time to give us a call.
