Thanks for reaching out, Cory!

When a fuse keeps blowing it means there is a bad wiring connection, a bad ground, or the unit itself is bad. The ground is the most common culprit so I recommend checking that first - be sure it's secured to a clean, bare-metal surface as even some paint can cause problems.

From there you'll move on to triple check that all of your connections are secure and undamaged.

If you're still having issues after checking all of this please let me know, and let me know the model of compressor you have so I can help you further troubleshoot.

Hey Cory, how did things go after you checked the ground and wiring on your Air Lift WirelessONE system? Were you able to track down what was causing the fuse to blow? Your update could make it easier for the next person with the same issue.
