Question about Carrier Heating & Cooling
Hi, if the motor is getting hot enough to shut down on its internal OL, you are loosing the motor. Even though you have a 3 phase panel, this motor will only be a single phase motor. Sounds as though the run capacitor is doing fine if you have no oil leaks, or swollen areas on it, so if you had a clamp around amp probe you could check the R.L.A and compare them to the motors data plate or sticker on the motor housing, or condenser it self. This would tell you that the motor is over amping. If this motor has oilers on it you can get a zoom spout oiler at a hardware store and give them a shot of oil. Some are sealed and you can't do this. Also, wash the condenser coil real good to keep the head pressure down, this will help. If it continues, you will need to get a replacement motor. There is a arrow on the motor showing the direction it turns, so when it runs, it is either cw or ccw. You can tell by the pitch of the prop, as it pulls air through the coil and out the top, so the blade/prop needs to scoop the air up, so look at the shape. The best way since it is single phase, is when it does run that's the direction it goes.The unit is 14 years old and thats alot of hours on that motor. I replace this motor in the summer more than any other part. Remove the fan guard and let it run. Carefully touch the motor to see how hot it is when it stops. I bet you can fry an egg on it. You will need a motor, but try cleaning the coil, and if it has oilers, oil them. This may keep it going through the summer. More then likely, the motors had it. Please don't forget to rate me and I wish I could give you better news, but its common to loose this motor as its in the heat all the time, and its hot when it runs. Please keep me posted. If this motor has ever been replaced before, they could have put a reversible motor back in. Just look at the prop when it turns and you can tell as it will scoop up the air by the pitch of the blades. Please keep me posted.
