Help!! No cooling, just fan!!!

I HAVE A LESS THAN 2 YEARS OLD AIR CONDITIONING (MODEL#FA4BNF036) THAT HAS STOPPED COOLING. I SEE NO LEAK AND HAS BRAND NEW FILTER. IT'S A SINGLE UNIT FOR CONDOMINIUMS. i THINK THAT THERE SHOULD BE A WARRANTY STILL, BUT TO GET TO SERVICE IS BEING A PAIN. CAN ANYONE PLS GIVE ME AN IDEA HOW TO GET IT WORKING AGAIN?

Comment by CAAAPEREIRA, posted on May 08, 2008 Yes, I can hear the fans running, but I will have to open the panels to verify everything else. The thermostat shows cools and I have programmed it for the temperature to hit 70F. But the temperature does not go below 79F. Does these kind air conditioning have internal fuse? My apartment lights blinked yesterday and I notice that after that the air conditioning stopped working properly. I pressed the "Reset" button on the digital Thermostat which displays "cooling" but it acutally does not! I HAVE A LESS THAN 2 YEARS OLD AIR CONDITIONING (MODEL#FA4BNF036) THAT HAS STOPPED COOLING.

Cool air blows from the vents but the house is not cooling off. I have a Trane.

Air Conditioners Cooling Tips


  • Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic.
  • Set your thermostat as high as comfortably possible in the summer. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
  • Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
  • Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use.
  • Avoid placing lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
  • Plant trees or shrubs to shade air conditioning units but not to block the airflow. Place your room air conditioner on the north side of the house. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.

    AIR CONDITIONER IS NOT COOLING, USING GAGUE, FOUND BOTH SUCTION AND DISHCHARGE PRESSURE VERY LOW. IT IS R22 4 TONS AC UNIT, SUCTION 10 PSI, DICHARGE 80 PSI. COMPRESSOR AND FAN RUNNING.


    there is probably a leak in the systems somewhere, it needs to be inspected for a leak and charged with R-22 for proper cooling.
    There is a stop leak for air conditioning systems available to licensed technicians to buy, might work if the leak is very small.

    I have a blizard split model 10.5 years old in a caravan. model sa101 the air feels cooler but seems to have no noticable difference in actual temperture and compressor seems to run continuously ...


    Please understand first, air conditioning system not only cooling the area but also removing the heat. If heat in the room stays constantly, even 24 hrs running a/c couldn't cool the room.
    Now, why the a/c could not cool the room or remove the heat from the room.
    Check air filter, evaporator coil and blower wheel for clean. If not service the unit immediately. And also check indoor fan motor rpm. If rpm is low, replace fan capacitor. Check for gas pressure to confirm no leak or running with short of gas. It's advisable to service both indoor and out door once in 6 months at least. Otherwise, your electric bill will kill you lot. Thanks.

    Fan works, air conditioning does not. Try resetting the power (in the proper sequence - outdoor unit followed by indoor unit). Air conditioning came on briefly (less than a minute) than stopped, leaving...


    Without seeing the unit,

    1 - the condenser fan (which is in the outdoor unit) could be blown. This would cause the unit to go off on high head pressure.

    2 - it could be low on refrigerant, which makes it do nothing but blow room temperature air around. The unit would go off on low pressure

    3 - the filter is dirty, blocking the cooling

    4 - the compressor could be shorted, or a corroded wire somewhere that feeds the contactor

    Mr. Slim Ductless Splits are the best on the market and should only be repaired by a trained technician.

    Hope this helps.

    When the control is set on air conditioning, it has recently started to dehumidify also on that setting. What to do? The unit is 5 years old.


    I'm sorry is the unit set on COOL (snowflake) or DRY (raindrop) All air conditioner will dehumidify when in cooling mode. That is just the dynamics of air conditioning. The air should still be cool depending on your settings. if the air is not cool and you have confirmed that it is in cooling mode, check that the filters are clean and if they are have the system serviced.

    I take the time to answer your question, so please rate me.
    Thankyou Mat

    AC not cooling during the day


    Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

    Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

    Your AC is also five years old. Please avoid frequent opening of doors or windows.

    Ensure that the exhaust fan and the blower of your unit are functioning normal.

    The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

    Help!! No cooling, just fan!!!


    you probably have a defective contactor or start capacitor on condensing unit. if you pretty handy with wiring go to the condensing section open the panel. you should see a contactor (it's the little black piece with all the wires) check the condition of it. next to it is a capacitor and by the problem that you describe it could be that. check it if it looks bloated there's your problem just go an get an combination capacitor and wire up. (make sure the power to unit is off first. any other questions email me @ hvac.tech7872pr@gmail.com
