Amana central air codensor motor
Hi, not sure which motor you are talking about, the indoor blower, or the outdoor condenser fan motor? Doesnt matter. If the motor is shutting down, its overloading and going off on its internal overload. Cools down, resets and repeats this again. Make sure you have not miss wired it. Even though the run cap and motor is new, doesn't always mean they are good. You need to look at the R.L.Amps on the motors data plate, to see what it is rated for when running.You MUST have an amp probe meter to check each hot leg to this motor to see how many amps it is pulling while under a load. If it is the condenser fan motor, and if the blade/prop is not in the right place on the 1/2 " shaft, you can move it up or down to adjust the amperage on the motor. When you do this, it causes the motor to draw either more or less air across the coil, which you need less to reduce the amperage and load on this motor. I have seen this happen many many times, but like I said you will need a amp probe meter to see what the motor is drawing. If you dont have one, just move the blade a 1/2" in one direction or the other until the motor keeps on running. This will work, just time consuming, and you will never really no how many amps its drawing.You can pick up a good clap type amp meter at Sears, a Craftsman for around $29.99. It is well worth the bucks to have. You can also check the uf's on the run cap. The voltage 370 or 440, food for thought is you can always use a cap thats higher in voltage but never lower. Make sure you have the correct MFD as I am sure you know this.So, check the voltage from the new contactor to the motor, the run cap, and most important is how many amps it is drawing and you can wrap it up. I wish you the best. Please let me know, keep me posted, and rate me if you please to.
