Great service and parts availability
E-Replacement Parts has always provided great service and the parts I need. In the years I have purchased from them, they have always had the parts I couldn't find anywhere else. If you need it they will have it. The pressure switch I purchased is not available from Sears anymore and they had it.

I made this repair more complicated than it probable needed to be. Apparently air coming out of the unloader valve when the compressor is pressuring up isn\'t usually a sign of a faulty unloader valve. It\'s usually an indication of a bad check valve. It\'s an old compressor so I ended up ordering a check valve and complete pressure switc
... Read moreh. Pretty straight forward repair.
1. Remove all lines attached to the check valve and pressure switch.
2. Remove check valve and replace with new.
3. Remove the plastic housing from the pressure switch and unwire it. Don\'t break any wire terminals like I did. Remove gauge and fittings and set aside for use on new switch. Unscrew stripped pressure switch.
4. Install fittings but not the gauge on new pressure switch. Thread pressure switch tightly into fitting coming out of the tank.
5. Reconnect all lines to the new check valve and new pressure switch. Push the end of the aluminum unloader tube into the unloader valve tightly then thread the other end into the check valve.
6. Install gauge into new pressure switch.
7. Reconnect wires to the appropriate terminals in the new pressure switch. Replace black plastic housing.
8. Check to make sure it works and nothing leaks.

value and checked for air leakage.
I removed the old switch, cleaned all the components and thread taped all the connections, and reconnected the new switch.
(My Sears compressor has a proprietary pressure cut-off attachment, so I couldn\'t use a knock-off brand. In the end, although 4 times as expensive, the repair came out just fine.)
Ensured the power cord was unpluged. Removed the old pressure switch to include electical and air line return. Removed the pressure guage and air release. Installed the items on the new switch, connected the electrical lines, secured the switch cover and tested. All worked fine.
