67696 will not stop

I live in Sudbury Ontario Canada

I have a 6 gallon pancake style compressor item#67696 which I recently got as a gift.
I followed the directions close the regulator valve close the drain valve and attached the air hose then plug in the power cord and turn on the switch.
So far all was well until the compressor built up over 150psi then the relief valve opened as the pressure switch failed to open stopping the compressor motor

67696 will not stop

If power is still going to the motor and the compressor is running after the tank pressure bypasses the cut out setting on the pressure switch, then either the pressure switch has failed, or it's wired incorrectly.

Yes, the wire locations matter.

One side of the switch is the power in from the line and the other is the motor load. If you mix them up, you will get a compressor that may not stop at the cut out.

PRV works @150, however I replaced pressure switch and still the unit arrives @ 150 without shutting off automatically.
Checked all connections & all got & tight. Will the wires going to the Pressure Switch matter onto which terminals?

I've got the same problem with one of these I just bought second hand. Where can the sensor be purchased?

(If you Google Pressure Switch for 67696 air compressor you will find many sources. Make sure you have removed the existing one so you can compare it to images on line to be sure you get the right one. - Moderator)

On the bright side, the PRV works. This is good.

If you can easily return it, do so.

If you want to do some basic checks to see if it's easier to fix it, then pull the shroud and look for a couple of wires going to the pressure sensor screwed into the tank.

One will come from the power switch, and the other off in the motor's direction.

Check that the terminals are not bent so as to be shorted. If not, then chances are the sensor is bad. A replacement is around $10 U.S.

Good luck.
