Sears air compressor throws breaker
I have come in possession of a Craftsman model 919.165200, 5 hp, 20
gallon air compressor that when turned on runs for a few seconds then throws a breaker in my shop. Anyone have a clue as to why or how to repair? Anyone come across this problem before? TIA Jerry |

Upon inspection I discovered the ground and neutral wires had been reversed. Fixing this stopped the GFI from tripping but it tstill tripped the breaker till I ran a 20 amp circuit. |

Is your shop heated? What's the temperature of the compressor when it
trips the breaker? wrote: I have come in possession of a Craftsman model 919.165200, 5 hp, 20 gallon air compressor that when turned on runs for a few seconds then throws a breaker in my shop. Anyone have a clue as to why or how to repair? Anyone come across this problem before? TIA Jerry |

To many variables. What is the nameplate voltage and running amperage(fla)?
Is the motor connected for 120 or 240 volts? Is the 20 amp circuit you're connecting it to, a dedicated circuit? Do you know that it is or was in working condition? Is the tank empty or is there compressed air in it? wrote in message oups.com...

If all else is up to par, that would be my guess as well

TIA Jerry A compressor that size needs the motor set for 220 volts and 220 volt service plumbed to it to drive it. Even if it has a 120 volt setting, its foolish to run a motor that big on it. My craftsman in my garage is 220 volt. I had to run a special line out there to do it. I just stole the unused dryer AC feed and rewired it.

compressor oil low? That will put a tremendous load on the motor. |

1. using an extension cord with the compressor. Yup. If the extension cord is too long the voltage drop will trip the breaker. |

A "5 HP" motor might really be 2 HP or less. My current 6 HP compressor runs on a 20A 240V breaker, and it doesn't put out as much air as the ancient 1.5 HP compressor that it replaced when the old one finally bit the dust. Best regards, Bob |

7. a bad unloader valve (maybe that's what you meant by the pressure switch) My CH compressor manual calls it a pressure switch. It's a pressure operated contactor that opens the ac line input when it gets to operating pressure. I once had a pressure switch go bad (weak spring & arcing contacts) and it would trip the breaker like the OP described. -Bob S. |

But there is no way a 5 HP 110VAC or 220VAC single phase motor will run on a 15A circuit. |

wrote in message ups.com... 20amp breaker I have a 4hp compressor that requires a 30 amp breaker. Did you have to put a new standard plug on the cord or special outlet in the wall to plug this in? If so, you most likely did not put in a big enough breaker. Also, you cannot just put a bigger breaker in and the corect outlet. You will need to run 10ga wire to the outlet. standard 12ga is way to small!.

Bob Since it is running a few seconds, (like 10-15 seconds), might that indicate that the run capacitor is the culprit? I have no way to test the capacitors. It has 2, 1 of which is a G.E., (I think it is the run capacitor), & the other is a Mallory, (which I think is the start capacitor). I can find a replacement for the G.E., but I would have to replace the Mallory with a different brand. The Mallory is 400-480 MFD, 165 VAC, but the nearest replacement that I can find, w/o having to buy about $100 worth, is 400-480 MFD, 125 VAC. Sears doesn't list the capacitors as replacements & the complete motor w/capacitors is $230. At that price I might as well buy a new compressor & tank. Jerry |

Check to see if the capacitor has a voltage charge after being plugged in (With Plug REMOVED FROM OUTLET!!!) Check Ohms of capacitor. It probable is open? The other Capacitor is probale good but check that one also! Please remember that Ohms are checked with out current applied. Anybody try this web page for the exact Capacitor?

http://www.thestuccocompany.com/main...er-239451-.htm : Update to previous post from camocs: Found the site that sells individual capacitors. There is a minimum order of $30 dollars. I bought two to avoid the surcharge of $14.83. Bill came out to 32.50 and with shipping came out to 41 bucks. I keep you posted if this is the fix!!! I have come across so many of these compressors that throw breakers and My girlfreind just bought a mini compressor from sears that did the same thing. I took it back for her and got a new one after opening three boxes to get one that wasn't dented or wasn't covered with oil or even having parts missing on an unopen box. This isn't the Quality Controled sears that I grew up? I have been using Craftsman gear for 35 plus years. It's insane that we live in a throw away world. Recycle those old compressor. Keep the Old Gear in shape and it should last a lifetime!!! The website for the capacitor is Onlinecomponents.com. Search for PSU40065A. The PSU40065 is too long for this apllication. Since I bought two, I probable will sell the second at a fair rate plus shipping if anyone is interested? Good Luck Ya,All!!! ------------------------------------- camocs wrote: camocs had written this in response to http://www.thestuccocompany.com/main...er-190003-.htm : Mallory 400-480MFD 165 VAC is BAD!
