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.

Central air conditoner outside unit

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.

Trane Weathertron xe 1000, outside unit has hum and fan is not working. unit is 7 yrs old,never any other problems.

Hi, Trane weathertron are top of the line units, and I have had extensive schooling on all tranes, commercial Intellipaks and Voyagers. If the fan has stopped, the bearings in this fan are failing and that's what you hear humming this motor or most likely the contactor. If it is easy for you to remove the fan guard ( power off ) you can turn the prop/blade and see how tight the bearings are. Carfefully, place your hand on the body to see if it is hot. If the hum is not from the motor, it will be from the contactor pulled in when in cooling mode, causing a load on it due to the condenser fan motor failing. Look on the front and rear of the motor for small caps that would be for oil. Most motors have sealed bearings now, but they still use ones that need a few drops of 20 weight oil during service of the unit. If you do, you might try going to a hardware store to get a plastic oiler bottle with the telescopic spout to reach these bearings and try to oil them for a $1.20. This may get you back on line again, only if you do have this type of bearing. Another part to check would be the dual run capacitor in the control section on the outdoor unit. Normally round and silver/gray in color, some are plastic and they look like a small can of V-8 juice with several wires coming out the top. Others are shaped like a flask without the top, lol. It will have 3- sets of connectors on it. Marked Herm., fan, and C for common. Look it over well, at the top, sides, and bottom. If you see any sings of a swollen and distorted top or body, the top swollen up, like its ready to burst, or it has and you see oil all over it, this is why the motor has failed or will not run. Replace this first as the cost is around $15.00 or so. If you have a Granger's supply, they will have them. If not, a appliance parts house. This capacitor gives your condenser fan motor and compressor a boost upon starting and keeps them running a speed at all times. If they fail, the motor could or will fail in time and so will the compressor. If it looks good, no oil leaks, you will need to have your condenser fan motor replaced. This motor works the hardest of all, in the heat plus the heat the motor gives off so its not unusual to loose this motor. At the start of summer, my crew no to stock there vans with all types of condenser motors and run caps, 1/8, 1/4, 1/3, 1,2, 3/4, and 1h.p. on commercial units. On your contactor, you will see it, it has either 1 or 2 sets of contacts on it and this is where your high voltage leads come in and connect. They will be black and some burned places. I would with power off if you have a small piece of fine sanding cloth or paper is to try and clean them up some. This is not a must. So, if all looks good, and the motor is hot, it has failed. A a/c company should charge you around $150.00 to replace this motor and they come with there own single run cap just for the motor. They will need to make a few changes on the wiring of the new motor and cap. Its around a hour to change out, plus maybe a truck or trip charge. Ask them about all charges. I am sorry for such a long solution, I just wanted to tell you a little about your unit and give you some experience. Please keep me posted and rate me if you will. I will be here if you need me for anymore help. Thank you for using

Trane XE 1200 ac The outside fan stopped

unless you have a meter youneed to see if the unit is asking the fan to turn on. if so the fan (which i doubt) maybe gone bad or the starting capasitor for the fan... is there anyway of checking the voltage to the fan

Compressor fan motor runs backwards

Most likely a bad motor or bad capacitor. I would check the capacitor first as this is probably a $20 fix. The fact that it runs in the correct direction but at a reduced speed really leans hard to the capacitor.

Good Luck and hope this resolves things for you. Let me know.
