Maybe I can help with that. Anyhow, can someone tell me the best place to locate the correct capacitor? It runs off standard 120 Volt household current. Thanks no electrician david. I press the reset button and it works for 20 more seconds or so. The motor windings or any other electrical connections inside the motor may be shorting and this sudden flow of electricity pulls too many amps. What pressure does it reach before the breaker pops, and is the breaker popping at the same pressure on the compressor every time? When they lose capacitance, that can cause this, even though its not clearly bad as in open or shorted. I have a 10-year-old Campbell Hausfeld 5HP 120v on a dedicated ckt. There are a number of reasons why an air compressor circuit breaker trips. If the problem persists when you have clean power, then it might be a failing pressure switch allowing a short and popping the breaker, it could be the motor is laboring and pulling too many amps, it could be the start/run capacitor isnt working right many things. by-pass the reset switch. :~fZX\f~_~}}YZ/#Wk_
x/_/{mmo[j!kit"~2+ Vincent, if this was my Campbell Hausfeld air compressor, from the symptoms you describe, I would be checking out the start capacitor. /PageLayout /SinglePage
If thats all good, make sure your intake filter is clean, and then, its time to check your capacitor. Close the drain and plug in/turn on the compressor. Regardless, if you are not using an extension cord and the problem persists with no load on the motor, then yup, the first thing to look at is if the start and run (might be two might be two in one) capacitors are OK. See that page for details and then update us if that was the issue, would you? 120 Volt" is in sale since Sunday, November 7, 2021.

I swirled to a 30 amp bereader and it ran for 5 seconds. These results match your search query. If your compressor is large enough and has a start capacitor, its likely that your circuit breaker trips due to the failing of the capacitor. However, every time I let the compressor restart without either releasing the safety valve between the two cylinders or blocking one of the intake ports the motor struggles to get the compressor running between the start and run and the motor breaker cuts off after about 2 seconds or so. Before I buy a new motor though, could it be the check valve or pressure switch malfunctioning? This one blows the 20 amp breaker. I tried removing the tube and it didnt change the situation. Sorry. Don't get scammed by websites pretending to be Harbor Freight. 120 Volt. <>
It is therefore important that you change your air compressor filter often to avoid this. When the air pressure in the tank drops, a small diaphragm inside the pressure switch moves and forces points inside the switch to touch making a circuit. It can be a problem when the circuit breaker constantly shuts down your air compressor. I have a 5-year-old central pneumatic 21gal compressor model 61454 that keeps tripping the overload protector.

From day one I have to hit the reset 10-16 times before it will stay running. I noticed the psi gauge dropping then the motor started to hum but the compressor was not working. Add the belt, you increase the load, and the motor cannot start against it as, I suspect, the start capacitor cannot deliver the added power to get the motor going. Note: some small compressors may not have a start capacitor as they have sufficient current in the electricity flow to start the motor but larger compressors will require this additional inrush current of the start capacitor. I have narrowed it down to the motor and want to know if you or anyone else has solved and fixed this problem, also how much time and money were spent doing so. What I am saying is this, the only wire between the motor and the power is the cord of about three feet long, a temporary outlet, and a breaker. 4 0 obj
