Motor Unit

how do I test a fan motor of central air unit? central air is a Trane unit, replaced both caps, fan motor, 825 RPM, 200-300 V, 60 HZ , 1/5 hp, Ph 1 GE If the motor in question is the cooling motor for the condensor outside, it is simple. First a little troubleshooting tip. Check the fuses if you are thinking the motor is bad, but just replaced it. If you replaced it with a used motor make sure the phases are correct. Residential uses single phase so I am assuming it will be residential service. Make sure you didnt put a three phase motor in its place. OK shut off the thermostat, shut off the power to the unit. pull the cover off the unit and check for any loose wires, burn marks, blown fuses, ground, anything unusual. If it all looks good find the relay that controls the motor. It will either be a "ice cube relay" or a manual relay. Ice cube relays look like a little clear box with a small control relay inside. Manual relays will be open,usually with 2 to 3 copper poles showing, in which case you can take your plastic screwdriver handle and push it in momentarily, after you turn the power on, to see if the motor turns. If it is a ice cube relay consult a electrician for the proper jumper setting to bypass the relay. Yyou can always do it the old fashioned way. Take the motor back out and propely hook it up to a external power supply of the same voltage and see if the motor turns. Whatever you do, be careful with electricity, it is not the voltage that kills you, its the amperage. If you do not feel comfortable doing it - DON'T. Good Luck!
