My compressor Campbell Hausfeld WL650202AJ will not start. I have used this compressor for many many years.

I watched the eReplacement video on how to replace the pressure switch. it was direct to the point except for the copper wire cable with a plastic end connected to the pressure switch. it was not on the video and i could not find anything on how to disconnect. So i looked closely - ---to remove turn counter clockwise 1/4 turn to align the notch with the plastic tongue then pull out - to connect back - align the plastic tongue to the metal groove push and then 1/4 turn clockwise. Make sure everything is connected (all wires) before plugging in and turning it on. I am happy that i can use my compressor again.

Pressure switch failed

Remove the parts that are not on the new pressure switch and set aside. Then open the electrical cover on the switch to remove the wires. You may want to make a wiring diagram. Then take off the broken pressure switch and put the new one on. Hook up the wires, then put the cover on. Then get all of the parts that you set aside and put those parts on the new pressure switch.

The right part

Needed a part for a air compressor that is 10 plus years old. It was just what I needed and I was able to find it on the sight easily.

Replacement part for discontinued one.

I have shopped e-ReplacementParts many times in the past, Good service, good parts, and good prices. This part was a challenge. I could not find the exact part here so I went to the manufacturer site, clicking on parts there, I was directed to this site, surprise! I talked to a rep at e - ReplacementParts and he said the part was discontinued and this is the replacement number. I ordered it, arrived as expected. This part had all the right connections, just not in the right places. I had to get some extra airline to make it work, and some mods to the cover to get it back together. The 4 stars are for the inconvenience, not the quality of the part or the service. Just be aware of replacements for discontinued parts. I will continue to shop here for parts first.
