We purchased a home a few years ago and it has a radon mitigation system. I just happened to go downstairs and look at it and noticed this reading. What should I check? Should I be alarmed?
Thank you for the link to the manual. The fan is on a pipe coming out of the house and is plugged in to the outlet on the side of the house. I can't tell (tried both listening and feeling for vibration) if it's running and I checked to ensure that the breaker hadn't been flipped.
As for checking the oil - I haven't quite been able to figure out how to do that.
