My frigidaire air conditioner is making my apartment feel damp and when i took my filter out to clean it that part was damp too! What do I do to fix this?


You may have a clogged drain or the unit is installed without enough angle pitch for the water to drain to the back of the unit toward the outdoor section of the unit. I'm assuming it's a window air conditioner? The moisture condenses on the cooling coil near the filter and should drip down into a condensate drain pan, then the water should drain to the back of the unit into a pan at the condenser coil fan that is rejecting the heat outside. The fan blade usually has a ring on the outdoor fan that pick up the condensate moisture the fling accumulated water onto the hot condenser coil to evaporate it. Also the filter should not be touching the cooling coil. Make sure it in the correct slot. Some a/c cooling coil require a wetting agent that allow the water to slide down the coil and not pull off of the coil into the indoor circulating fan.

Outside temp was 113, the compressor stoped fan stayed on.Only hot air. Latter in the day compressor and fan worked fine. Should I be concerned ? Thank Mike duo therm 13500 .no heater


Hi,
It just got so hot that the unit kicked out on high head pressure...
Check the outside condenser coil for dirt... wash it out with soap and water so that you can get maximum air flow through it...

Cleaning


If practical - the best way to clean a unit like you're describing would be by using 'air pressure,' to blow the dust out of the coils, squirrel cage, and in and around the fan motor and compressor.

Then take a water hose and wash both coils being real careful to "not" get water in the fan motor. Note: the compressor is sealed so you don't have to worry about it, but try to be careful and keep water out of the controls/wires (you might even use plastic to protect them).

Also, be sure you install a 'clean/new' air filter in the unit itself. This filter goes in front of the evaporator coil which is the coil that gets cold. The other coil - the condenser coil (the one that gets hot) does not need a filter.

good luck!

My split system gets cold for 1/2 hour then blows hot air, and then it will only blow hot air


1. Check to make sure everything in the condensing unit (outside unit) is running....compressor, fan motor. If you do not have electrical experience, contact a qualified service technician.
2. Check to see if the condensing coil is clean. In many cases this can be cleaned using a garden hose.
3. Check to see if there is any ice or visibly frozen areas. If so, ensure your air filter and your evaporator coil (coil in the air handler) are clean. Ensure your return grille and supply vents are open and not blocked.

Hope this helps. Good Luck! :-)

Fan Coil Unit is Cycling on and off. But the room is still hot.


Check electrical connection at the T'stat and the indoor blower . Sounds like a loose connection.

Hot Frame


the hot frame is due to poor or no air flow across teh condenser coil located in the compressor compartment in the rear of the unit. pull unit from wall remove card board cover and there is a fan that should be blowing. while you have it pulled apart be sure to clean the coil. the jelly roll looking peice the motor is mounted to. if the motor is bad you can put a house fan blowing on it until you get a ne fan installed. thx peyton

My blower motor doesn't blow air out the air ducts why


Check for a frozen cooling coil. Turn the fan to the on position at the thermostat and the cooling to off. Your cooling coil may be iced over. Allow it to run in the fan only mode until the coil has had a chance to defrost. At the outside unit you may see the large line is frosted. This is the visual indication for a frozen coil. When you return the A/C to cooling use it with the fan on while in the cooling mode.
