Capacitor replacement for generic compressor
- Thread starter John1205
- Start date
Not enough info here to help properly. What does owners manual say about breaker size or current draw etc, What size breaker are you using? How old is the breaker? Are you using an extension cord? Does the compressor have a built in overprotection circuit? A reset?

Any extension cords should be 12 or 10 gauge, under 25 feet if possible. Breaker for a YH style compressor must be at least 20 amps. Compressor draws more power as the pressures go up. As stated above, nothing else should be on the breaker if possible. If there is another appliance on the breaker, it'll pull too many amps and trip the breaker.
More info needed.

Also the new compressors are pretty famous for drawing a bit more current until they wear in a bit.

Thank you I have a small fan and the water pump on the power strip. The power strip is#12 and 20 amp rated. The compressor is on a Arc fault breaker and I tested it on different breakers and it trips all. I let it run for three minutes and closed the valves and it trips after 2000 . It's on a cart so I put it on GFI, and Arc fault, and a regular 20 amp. I'm thinking the capacitor is going out on the run side. I looked at it and I can't see anything on it. No mf rating or anything like a label. I'm flying blind and was wondering if anyone else has been here. Thank you for your help

Thank you again and I forgot to mention is the compressor was working for three months on small tanks and guns. Right after Christmas I was going hunting and was going to top off the Texan and it tripped the breaker.

So it trips on a non arc fault, non GFI, 20 amp circuit with no surge strip? Is this correct? What compressor are you using?

Running for 3 months fine than suddenly trips breakers is a big point. You say your flying blind, but, you manage to locate a run capacitor. Is there a start capacitor installed also? Most single phase 120vac motors that employ a run capacitor also have a start capacitor. The start will be the larger if the two and is switched out once the motor reaches speed. If you are saying the unit starts, runs, and will produce 2000 psi then trip the breaker, then, while a run capacitor could be the problem, it could also be the motor itself is failing. A motor will run without a run capacitor but would eventually overheat. You could monitor current draw, but, the reality is the cheap 110vac motors are not known for being reliable or rugged. Working for 3 months filling bottles and guns may be all you got from her. You could lookup how to size a run capacitor and pay the $10 for one but don't be surprised if the motor itself is the issue. Good luck with DIAG and let us know what u find.

The only manual is a set up and use manual. It has no specific rates for anything. It's a 110 cord with a 15amp plug on the compressor. 20amp is breaker size and the compressor is the only load on each circuit I tried.

The capacitor I found looks like a combination capacitor one feed in and two out. Run and start in the same?

A dual run capacitor supports two electric motors, with both a fan motor and a compressor motor. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals, labeled C for common, FAN, and HERM for hermetically-sealed compressor.

Thank you so much for your help. The seller is not in business anymore. I found a listing for it and it's a 8 amp rating and a 1800 watt rating for the motor. Got a splitter and two adapters to the dryer plug and the washer plug has the pump and fan. Got it up to 3000 and I shut it down. Wife has noticed a smell and I have not tried again. I was hoping for a easy fix for something cheap.

looks like it will be toast soon if you try to run it. Replacement motor/repair would cost more than the compressor is my guess. Sorry for your loss....bern there. I have a new compressor from Tuxing on order and 
with the spare parts I have as backup hope to get a few years or more. I use Secolube 500 oil and 50/50 coolant water mix. This hobby ain't cheap fur sure but sooo much fun. When my Huben K1 puts out a string dime size at 30 yrds I forget about the pumping session to come.

I’m guessing the windings are burning the insulation off under load. You seem to have gotten the average use from these air cooled box compressors.
