CH compressor won't build pressure
by: Bill

If the compressor is running and nothing is showing up on the tank gauge, either the tank gauge is broken or there is no air being generated. You may want to check and see if the compressor tank gauge is working. If you can swap it with the one on the regulator as a test, that's good. Odds are both gauges haven't failed.

Then, if the gauge is good, see the troubleshooting pages about why air compressors run but don't build pressure.
