Compressor would not turn on without holding switch in on position.
My compressor got to the point where I had to remove the switch cover and bump the auto/off trigger on the switch to get the compressor to start every time the pressure dropped too low to use. This compressor is 15? years old and I wasn't sure the new switch would fit but it worked out great! My compressor was sitting unused for the last three years until I had to try and get it working again to get some work done on my house. I also replaced the pressure gauge and regulator with parts from the auto parts store which is why the repair took so long. I also spent some time on YouTube researching the unloader valves so I wouldn't screw it up.
The compressor parts are metric but all the pipe fittings are standard (9/16, 11/16). So you will need both metric and standard wrenches.
To replace the switch:

1. Make sure the compressor is unplugged.
2. Remove the pressure switch cover. Disconnect all wires and label to ensure proper reconnection. An impact driver might be necessary to remove screws without stripping them. Remove or loosen any cord clamps on the pressure switch box. Pull cords out of pressure switch box. Set aside the cord end in a safe place.
3. Disconnect the nylon unloader line at the check valve (end of unloader line NOT connected to pressure switch, 12mm wrench). This will make the next steps easier.
4. Remove the pressure switch from the tank.
5. Remove the regulator, relief valve and gauge from the switch.
6. Disconnect the unloader line from the pressure switch. I thought about cutting the nylon line here but was concerned that it would end up too short. There are a couple different varieties of connection types. If you have a brass unloader valve where the nylon line connects to the pressure switch then you can take the unloader valve off the pressure switch by loosening a set screw in the switch body. To remove the nylon line from the unloader valve, the end of the valve where the line enters must be pressed into the valve, somewhat like a shark bite fitting. A pair of channel locks is helpful here.

This completes the disassembly.

Assembly:

Avoid using tape on these plumbing fittings. Instead use a liquid pipe thread sealant/lubricant. I had to redo several connections because they wouldn't seal with tape.
1. Install the unloader line: The unloader line can be connected to the valve on the pressure switch by pushing the line into the port until it clicks.
2. Install the regulator, relief valve, and pressure gauge on the pressure switch.
4. Install the pressure switch on the tank (no tape or sealant on this step). Connect the loose end of the unloader line to check valve.
5. Pull wires into pressure switch and connect as required. Clamp the cords. The new switch has clamps integral to the switch body so I didn't need the old clamps.
6. Replace the switch cover and you're done!

Bad pressure switch
Remove the parts from the old pressure switch, that do not come with the new switch. Then remove the cover on the switch and make a wiring diagram. Remove the wires from the old switch. Remove the old switch. Install the new switch and wire it up, replace the cover. Install the parts removed from the old switch to the new switch. Works like a charm

    Ordered the part on Friday afternoon and the part arrived the next day by noon. That’s without paying for overnight shipping. Compressor was up and running again quickly.
