C-H HL5402 off-brand - motor cycles past 30 psi

by Toby



I have an older off brand compressor made by Campbell-Hausfeld that I think is identical to the model HL5402, (oiled, 4 gallon, 1-1/3HP?, just painted red). It has no labels or tags anymore, and I can't find the manual.


I starts up fine, but at 30 psi, the motor sounds like it is cycling off and on. After taking off the shroud, I can see the centrifugal switch between the fan and the motor housing moving back and forth and arcing. It will even continue to build pressure, but will stop at around 80 psi (over heating?). First time this happened, it tripped the breaker when I allowed it to continue.

I thought it was the running capacitor, and purchased a capacitor kit, but that did not correct the issue.

Looked on here for someone with a similar issue, but couldn't find one.

Any help would be appreciated. It was a great little compressor.

cycling & voltage to air compressor
by: Bill

Good advice, Doug.

We're rural, and we see a voltage fluctuation +/- 10 volts as a norm.

Just sayin'....

Primarily the centrifugal, but the main switch too, if you can get to it.

Yes, 4V relative to the line voltage, which should be close to 120 give or take a couple or three volts.

Yes, I changed both capacitors.

I will check all connections for the wiring tonight.

Just so I understand you, when you say check wiring to the switch, you mean the centrifugal switch, correct?

And the voltage should be within 4 volts of what? the line in voltage? 115-120V?

Thanks for your input!

Could be the start cap is being switched out too soon, and or the run cap has a bad connection.

Try cleaning up the switch contacts, and double-check that the capacitor connections are solid - as in firmly connected and no stray wire hanging off the connectors.

Do I understand correctly that you replaced both capacitors?

Also, if all that is good, can you check the voltage at or close to the motor while it is running? It should be within about 4 volts or so of the voltage when it's off.
