Need starting and running capacitors for 8-182852-nu century motor on coleman 6hp compressor. Thanks!

I have the same model compressor. The manual in PDF format can be found at http://www.arkansas-ope.com/BP0501813.pdf

Hope this helps.

parts are available from any motor repair /rewind shop
capacitors are only specific for capacitance and voltage and can be obtained from the same shops or from e-bay
the pressure switch only switches the motor on and lets run until the full pressure is reached
it then switches off but switches back on when the pressure drops around 10 psi
If it was doing that there will be nothing wrong with the switch
if all else fails and it is a belt driven compressor get a new motor
The brand on the motor is immaterial as long as it is 5 hp or bigger and has the same voltage rating requirement

Your start winding in the motor is failing. You need a new motor.

Sanborn/Coleman was bought out by MAT Solutions. A website I found lists Sanborn/Coleman compressors and parts but it does not show your model number. It does say, however, to email them with your model number and they will be able to find your parts for you. I have included the link for you here: http://www.mastertoolrepair.com/colemansanborn-portable-parts-freedirect-drive-electric-c-271_35_172_178.html

Well, it sounds as if you have a Coleman rooftop unit. If you have a start capacitor with a PTCR (Postive Temperature Coefficient Resistor) then it is different than if you have a Potential Motor Starting Relay. Why are you replacing the run and the fan capacitor?

Here is a link to the documentation that you need. If you do not have a Coleman and it is in fact a Duo-Therm, let me know the model number and I will be able to pull up the wiring schematic.

Thanks,

Rate this please!!

I can't blame you for askig, but here's my response. 5 HP is 3750 running watts. or about 35 amps at 110 volts and it would take somewhere around 50 amps to start it provided the motor could even be wired for 110 which I don't believe it can and for that exact reason. I'm sorry, but it's just not practical.

It sounds like the internal circuit breaker in the motor is heating up and then the breaker trips to shut down the motor. This is the protection so you don't have a fire if the motor burns up. The smell you have is the coils in the motor. Sorry to say that you will need a new motor for this unit. I hope this helps out.

The fan only has one capacitor. The other two are for the compressor, one is a start capacitor and the other a run capacitor. A schematic should be on your fan motor telling you witch two wires run to the start capacitor for the fan motor.

This could be the problem. It is more likely that the motor bearing is bad. Take the fan capacitor and have it tested. Or replace it, (under $20). Was the fan motor loud before this happened? Hopefully it is just the capacitor, the motor runs $60 - $100 and is a FUN to replace.
