Trane xe1200 compressor fan motor only runs for about five minutes

You need new compressor (doesn't worth to repair old one). Take a look on amazon: Amazon com Trane air conditioner compressor. I hope this was helpful. cheers

Well, the answer is yes. I have seen a bad capacitor cause a fan motor to run backwards. BUT..... After replacing the capacitor and WIRING it up the right way, everything should be fine. A lot of aftermarket condenser fan motors are reversible, so it can run counter-clockwise (CCW) or clock-wise (CW). However, most factory fan motors come one directional and on your specific unit, the air should always push out of the top. Running the unit with the fan going backwards will actually some-what do it's job, but damage other components like the compressor because it runs at higher operating pressures than what it is designed for.

Have someone else look at it! That's going to be the best advice I can give you. If they can prove that a capacitor caused the motor to permanently run backwards..... I want to know! Hope this helps and good luck with your unit.

Hi,
The compressor start capacitor is bad...it is not giving enough "kick" to get the motor running...
at least it is a good idea to change this first because if this does not work then the compressor needs to be changed out...

Did the 2 fans have the same rpm. If there is not enough airflow through the outside unit the compressor will shutdown on high discharge pressure. Also make sure the fan blades are positioned right if there is a shroud for them. Did the other motor have a capacitor with it or did you use the 1 from the smaller motor. Sometimes the motor data plate will tell you what size capacitor you need. Let me know what you find.

Hi, you say you wired it back in? Yes it is possible for the fan to run backward if the motor is a reversible motor. And yes, if its not running in the right direction, it will not keep the head pressure down like it should. On a reversible motor, they have 4- wires at the rear normally, that you interchange to reverse it. I don't know what wires you disconnected, but unless this is a 3 phase motor which I no its not, you would have had to change those 4- reversing wires to make it run either ccw or cw. It will tell you on the motor how to do this and the rotation. The blade on the fan is positioned to scoop up the air when turning, so you can look at it and tell the direction it goes. Air is pulled through the coil and out the top, or your head pressure we stay high and cause damage to the compressor in the long run, or shut it off on high head switch. I hope this has helped you. Residential units are single phase motors that can only be reversed if made to be, and can be changed by switching those 4-wires around.

Sounds like you need a motor. You say "fans", is there two?

OK, locate the terminals on the capacitor marked "HERM"(Compressor lead), "FAN", and "COM".(common)

HERM and COM remian as they are.

The wire going to "FAN" (usually brown) will be placed on either terminal of the new capacitor. (This is the ((usually brown)) wire comming off of the fan motor.) An additional wire needs to be run from the other terminal of the new capacitor to the "COM" on the old capacior.

What you are doing is bypassing the fan side of the old capacitor but still using the compressor side of the old Cap.

The fan should have a wiring diagram on it to help identify the wires if there is no brown wire. The other two wires will be identified on the wiring diagram as well, but one typically goes to the contactor and the other to the board.

Most likely problem with a not-so-old motor is the run capacitor for the fan.

Some units have fan & compressor capacitor combined into one -- others are separate.

The capacitor can be tested with a multi-meter with an MFD setting -- it should read reasonably close to the specs marked on the capacitor.

Depending on the age of your Trane unit. The fan relay has a time delay. This is a solid state board on the relay. Most of the time they stick on or off. Check for loose wires. But start with relay.

the pro 300 is a single stage thermostat and can not be wired to control 2 heat stages seperately
