I have a model # WL670100AJ 1.7HP 26 GALLON. WILL NOT BUILD MORE THAN 90PSI. The compressor will run and pump until it reaches 90 psi, it will not go beyond that.

I have drained the tank, what can I do to fix this problem?

Tracy, are you using an extension cord? If so, is this new?

Are you hearing anything unusual from the pump, besides the pump running, when the tank pressure gets to 90 PSI?

What happens if you leave the compressor running?

A bit more info is required or, you can check out the troubleshooting pages on this site that offer links to lots of pages with info about what to do when your compressor runs but doesn’t build pressure.
