This is a common problem with any type air conditioner it is caused by to much humidity in the air when the unit is not big enough to Handel the cooling I would suggest getting a bigger unit, adding another unit or a dehumidifier, or setting the unit to a higher temp. then turning it down gradually to let the ice melt and take the humidity out gradually.

Model Number: UACC-036JAS The unit works fine. The problem is it doesn't shut down after the specified temperature has been reached. The furnace blower shuts down, but the ac unit keeps on running....


Hello, usually a stuck contactor coil will cause this on the outside unit. When the outdoor unit runs continously and the indoor blower does not run no heat is being absoebed by the evaporator coil and thus the line freezes. Replaceing the contactor will fix the problem.

A/C runs but Fan does not shut off when compressor stops. Raising thermostat shuts unit off. fan auto/ on switch works normal. what are possible solutions?


First of all, remove filter at ceiling and with a flashlight or other source, when Compressor shuts off, look way up inside where evaporator coils are and see if you can see ice, or frost on coils/fins. It may be freezing up and fan will continue to run to aid in defrosting.

UNIT WILL NOT COOL. FAN AND HUMIDIFIER WORK. THIS IS ONLY THE SECOND SEASON USED AND THE UNIT HAS NEVER BEEN SITTING UP AND NEVER LAID DOWN OR TURNED UP SIDE DOWN. WHAT IS THE PROBLEM?


Hello,
A portable air conditioner may not cool for several reasons. Check the filter by removing the unit's grill and clean the filter.
Also check for clogs in the evaporator or condenser coils by light vacuuming. Make sure the evaporator isn't frosted over, but if it is, allow it to defrost and normal operation should resume.
Lastly, ensure the ambient temperature is lower than your AC's set temperature, as this can prevent cooling. However, if all of these steps fail to resolve your problem, the compressor may be malfunctioning, and in this case, the compressor needs to be replaced or repaired.
In summary, if the air won't cool, remove the grill and clean the filter. Clean out any clogs in the evaporator or condenser coils by vacuuming them and scrubbing them lightly with an old toothbrush. And since fan is working, you compressor might be defective.
I hope the above information is clear.
Regards.

Unit cools great but when extremly hot weather occurs it eventually freezes up.


dirty filters in the indoor unit.As the ambient temperature rises the unit will work harder and longer,its fine when its just a normal day because the evaporator coil wont have time to ice up as the compressor will cycle off before the coil freezes totally,but during extreme ambient temperatures the coil will ice up as the compressor will continue running to reach set-point causing the coil to ice up

My condensor in the furnace ices up which restricts the airflow. Is this normal. When I shut off the air conditioner the ice melts and causes a minor flood in the furnace. thanks


The indoor coil or "Evaporator Coil" (condenser is the outside coil in air conditioning) should never freeze when an air conditioning system is installed, maintained and serviced properly.
The most common cause of evaporator freezing is a clogged or dirty air filter. Other causes include; a clogged or dirty coil; blower malfunction, filter too restrictive (in which case use a less restrictive type), undersized duct, closed and or covered registers and grills, and collapsed duct.
Another common cause of evaporator icing is loss of refrigerant in which case you should call a professional who can locate and repair the refrigerant leak and recharge your system.

My Coleman rv mach3 63134cst which is about 3 years old won't cycle and freezes up when it runs to long. Ice forms on coils.


If coils are clean, or have been cleaned recently, then check your discharge side of unit for restriction. It may require you to take down ceiling assy, to be sure that there is nothing blocking the duct work inlets, if it is a ducted system. Also if ducted system, make sure you don't have too many blocked/shut off. As well you should have a freeze probe, or round sensor in the coils at front where intake filter goes over, (evaporator) to sense the frost, and kick compressor out until it thaws. When was the last time the evaporator and condenser (rear) coils were cleaned?

Dometic Quick Cool compressor freezing and evaporator coil


Could be low. First check air filter, air flow, and evap coil to see if it has restricted airflow. If all seems well, its probably low. The specs will tell you what type and how much refigerant. To access system, you will need a gauge/manifold set, refrigerant, and a piercing or line tap valve for the low pressure side of the system. Of course, first, you need to locate and repair the refrigerant leak.

No cold air


hi..
The evaporator coils on the front of the air conditioner get very cold during normal operation of the air conditioner. As the warm moist air in the room comes in contact with the cold evaporator the moisture in the air condenses out of the air and attaches to the evaporator coil. As more and more moisture condenses the water begins to drip down into the base of the air conditioner where it is evaporated to the outside of the house.... so the problem might be in ur evaporator coil.. try replacing the coil if u are an expert or else with the help of technician try to fix it..
Is the thermostat knob turned to the proper setting? Is the compressor motor running? The compressor is a football-sized case with no apparent moving parts. It is located inside the air conditioner at the center. Is it humming or making any kind of continuous noise or causing the lights to dim? If it is making a continuous noise, and your air conditioner is still not cooling at all, there may be a serious problem with one or more of these areas:
Compressor
Condenser
Evaporator
These items are not user serviceable. You will need to contact a qualified appliance repair technician to repair these components.

If the compressor is not running but you do have power to the air conditioner there may be a problem in one or more of these areas:

Compressor
Overload and/or relay
Thermostat (Open thermostat)
Burnt wiring
Bad selector switch
Capacitor..

Duo Therm AC not working


If unit was freezing up the air flow would normally stop, until the unit is turned off and allowed to thaw. I suspect evaporator blower may have a worn out belt, or compressor is shutting off due to control or internal overheat. What is the age of the unit?
