Trane AC Compressor fan cycling on and off.

I have a Trane XL1000 3-1/2 ton unit, I believe with an upgraded Air Variable Speed Air Handler. Yesterday when I was outside I noticed that much of the time the compressor fan was cycling on and off very quickly. Like every 2-5 seconds. Then at times it would run as it normally should. We set the Thermostat at 80 in the house and its holding the temperature okay. Thermostat is a digital unit. Any ideas on what the problem would be?

Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad


If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

Why does my A/C condenser compressor turn on and off every 5 minutes?


You need good airflow across the indoor coil, the evaporator. Air warms the refrigerant. If there is no airflow, the refrigerant will come back out freezing cold (in liquid form) and can damage the compressor valves. Before charging any ac unit, good airflow must be checked for across both evaporator and condensor.
Too much, overcharging will cause freezing all the way back to the compressor in a capilary tube type of ac.
Where is it the refrigeration lines are freezing cold?

Why does my fan runs continus. and the condenser won't run out side.


The fan runs continously because your condensor is not kicking on and removing the heat. The thermostat needs to come under the set temp. to kick off the fan. If your compressor doesn't run and the fan on the outside unit does run, your compressor has an issue. If nothing runs outside, then your transformer on the inside unit(air handler) has an issue. This could also be a control relay on the condenser or the air handler.

3 ton condensor and 2.5 air handler


I hate to use rules of thumb but 500sqft per ton depending on your windows and insulation. you are probably ok with a 2.5 ton however it will not work with a 3 ton outdoor unit as you have figured out. depending on how long that ac has been in you may want to replace it with a 2.5 ton due to the damage to the compressor valves because of the mis match. or if the indoor is newer and the original system may have been a 3 ton then i would replace the A/H. and be prepared to replace the outdoor if the valves are to far gone. If the trane is a new high effiency 2 and the goodman is just a 10 SEER you may be able to have a txv installed on the trane unit and a kickstart device outside. but only if its a high effiency but their again if the A/C fails you couldnt have a high effiency 3 ton you would have to drop down to 2.5,

Temp in my home will not drop below 81 degrees


Air Handlers differ in the way they adjust there variable speeds. Carrier you just plug into a pin. Trane has dip switches with directions on the fan housing. Before you try to adjust please kill power to air handler. Varriable speed are very sensative to voltage. If I new your air handler brand I could help. But just check the wiring diagram and they may ahve dirrections on there for setting speed. Need more help call back Rus

Trane air handler cycling rapidly


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.

What tonnage are these units and is it a variable speed.


The heat pump model number shows that it is a two and a half ton unit. I am sorry but I am not familiar with the air handler model number.

How far from the house should the outside unit be located?


If your outdoor fan is a vertical discharge in other words if the fan blows the air up from the top of the unit then one foot from house is fine, but if it is horizontal discharge or blows it out the side then the airflow needs to be directed away from the house or the unit needs to be moved away from the house far enough that it doesn’t restrict the airflow.
For the blower running on high speed a 4 ton unit is usually 1600 cfm so on low cfm it may seem like high speed. There should be some speed taps on the indoor pc board and if you look in your installation guide it should tell you what taps you need to get the lower airflow if its not correct.
For the luke warm air in the 2 ton mode, the coil is a still 4 tons but the compressor now is only pumping 2 tons of refrigerant so the discharge temperature and head pressure will be much lower and that is what determines how much heat you get, so you will get less heat. The 2 ton mode is for times when you only need a little heat or cool, when you need more then you will get the 2nd stage which is the full 4 tons of heat.
