Ridgid Model OF5015OTS Stops Cycling

The compressor will run and build pressure just like it's supposed to, but it will not recycle. When it gets to the point where the compressor would kick in, it stalls out.

Compressor will build pressure to 150psi as expected. Pump valve has recently been rebuilt. Check valve has been replaced (assumed to be the cause of the recycle issue).

Success with my Ridgid Model OF5015OTS!

Compressor works great. Only paid $50 for this trip stack. Switch was $30. I think I got a great deal! Thanks again!

Unloader valve

You don't see it because in most cases smaller compressors have the unloader built into the pressure switch - that's why one end of that tube goes there.

There's a small chance you could repair it, but your best bet is a new pressure switch.

Have fun...

Doug, I did exactly as you said and loosened the tube. Cycled right up to 150. Then I opened the ball valve and it kicked right in to build up the pressure to 150 again. Now, I am having trouble finding a Ridgid part named an unloader valve on the parts diagram online. Is it the same as the pressure relief valve?

If the check valve were the problem, you'd also have seen loss of pressure with no tool in use.

So, if that was true, whether you noticed it or not, then the real problem is the unloader valve.

If you care to, you can verify this by loosening one of the connectors on the 1/4 inch or so tube from the check valve to the pressure switch. Then, aside from the continuous leak, you'll find it restarts as it should.

Good luck.
