Ac Condenser Fan Spinning Slow . Also replaced the three pole contact see it was extremely pitted. Check to see if the fan starts spinning. Cooling fan not spinning... Pics... ClubLexus Lexus Forum Discussion from www.clublexus.com When the fan runs intermittently, it could be one of two problems. Checked capacitor and it was spot on at 15mf and amp draw was spot on too at 1.5 amps. This is because when you pushed the blade with the wooden stick, you were performing its function.
Condenser Fan Motor Amp Draw. With a cooling fan, the greater the airflow, the better that fan's ability to cool a radiator. Guess what, it is a emerson, capacitor start, 1/2hp, 1100 rpm motor.

This one is a reality check on myself on trouble shooting here. Jesse claerbout explains how to check refrigerant pressures and amp draws at the condenser. Would that be the same for a condenser fan motor aswell?
Open The Blower Compartment Of The Furnace Or Air Handler.
The compressor and the fan motor operates, it takes voltage and it has windings inside the motors that create a resistance and you have amp draw. Thinking i got the wrong motor in there. This rating is on 460v 3phase service, and my customer actually has 480v 3 phase service.
Overamping Occurs When The Amperage Drawn By The Fan Motor Exceeds The Fan Motor Nameplate Amperage.
Causing it to overheat and shut off. This is a 1/3 hp 1075 fan motor 60*. If there is more than one wire per phase coming out of the motor, you would need to measure at the input of the control box.
Automotive Fans Are Rated At 13.5 Volts, And The Rating Is After The Motor Is At Operating Rpm.
He left after about 15 minutes of cool and then about 15 minutes after that the outdoor fan turned off. And we’re going to check the ampere draws of the condenser fan and the compressor, but first, i’m going to check my voltage. Since most oem motors only have 3 wires and most replacement condenser fan motors have 4 wires, this creates a little confusion.
The Reason Why You Saw Low Amps On The Condenser Fan Motor Was Because There Was A Dirty Condenser Coil.
Putting the fan back on. This one is a reality check on myself on trouble shooting here. The initial start up of the fan will have an amperage spike.
Put The Fan Back On, Making Sure It Is The Correct Depth From The Motor And Pointing In The Right Direction.
My meter show it draw 3.8amp. It is always best to check the specs on the fan blade before replacing the condenser fan motor on any unit, and especially on older models. Thinking i got the wrong motor in there.
