Nothing is wrong with you fans .The fan is hook up on a pressure switch so when compressor pressure reach a certain pressure the fan would run and when pressure drop the fan would shut off.

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

SOURCE: trane ac, inside blower does not stop

Hi, I want you to try a couple of things for me if you will. Go to the thermostat and remove the cover. Now if you have a small bladed screw driver, loosen all the screw on this next section and remove it. Turn off power to the unit, if it is a split system, turn off the indoor unit. Once you remove this section which is the thermostat you will see the subbase and wiring. Take the red wire loose and off of the terminal. You may have a red jumper wire going from RH to RC. Remove the red wire coming into the stat at either point. Give it a minute and see if the fan stops now. If it does, you will need to replace the stat. If not, depending on the age of your unit, if your high limit/fan control tripped, that will be the problem. Some units have a fan control combination high limit that trips causing the fan to run all the time. You need to take a look at your heater section at the front of it to see what kind you have. If it is a combination fan/limit. it will be inserted into the fire box. It is square looking box with a cover on it some with a auto/ manual button on them Sometimes the contats will stick causing the fan to run. They can be removed with power off and cleaned up. They will have a dial with a temperature reading on them which tells the fan to come on when it reaches this set-point and off when it cools down. It may have stuck closed. Check what I have told you with the stat, and this and let me know the age of heater and if it is a split system Trane with a remote condenser and furnace located somewhere else. Get back to me on this.

SOURCE: hi there, iwant some help in duct type air

I hate to say this but it sounds to me like you need a professional. You may hear some other advice but it's not safe for anyone to work on the outside compressor unless they really know what they're messing with. The fire and death by electrocution risk is very real.

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.

Ac problem


Turn the thermostat off to see if the unit turns off. If it
does than you must have had a call for heating or cooling.

Put into heating mode let unit turn on, lower the setpoint and unit should turn off. If unit is not heating
than you have a problem with the outdoor unit.

Putinto cooling mode, turn thermostat all the way down, let unit start turn thermostat all the way up
if unit shuts off, unit is operating properly

Trane XE1200 Fan Motor


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.

Trane Heater A/C Airflow Control


i had a similar problem, and a six inch duct and inline booster fan didnt help, the room was just to far away from the furnace and ac. to save energy, i use an oil rad in the winter, and a portable ac in the summer, it works great.my house is a back split, so its a common problem. in the summer, all downstairs dampers should be closed to push the cold air upstairs ,as it will come back down anyway and the basement is cooler as it is. so if you have 4 flores, you close the bottom 2. bungalow you close the basement

Recharge air condition


Hello,

If you have solid ice build up on the "big" pipe (suction line) and very little air coming out of the vents, it's more an air flow problem; Inside fan not working, dirty coil inside (evaporator) or block filter. Open the cabinet inside and take a look there first.

This should be easy to fix; if the filter is dirty, replace it. should be done every month anyway.

If the coil is dirty, depending on access there's a 50/50 chance you can clean it you're self. If you can't you will have to call a technician who will pump all the freon in the outside unit, disconnect the coil, clean it & reinstall it, that should run you $200 to $300

You say there is a little air coming out so the fan is probably working, but if not, you will to find out why the fan is not running. That's electrical, could as easy as the thermostat is not turning the fan on to replacing the fan it self.

It is possible to have frost coming back if you are undercharge (low on freon) But the conditions have to be just right. A Journeyman mechanical carrying an EPA license working under A license contractor is the minimum you need to be able to buy freon since the 90's. that's legal of coarse.

To charge a system you also need a set of gauges and you need to know the working pressure of the system depending of the freon inside.

I think you only have a block filter or a dirty evaporator, possibly a collapse duct.

Good luck

Loud AC unit outside trane high efficiency xb1000


The noise could be the fan trying to pull air through the condensor. Service cleaning should improve cooling and lower noise level.
