Hi,
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
The air is cool but doesn't seem cold enough
If
the air doesn't seem cool enough it is necessary to use a thermometer
to check the difference in temperature between the air going into the
unit and the air being blown into the room. Ideally, the temperature
difference should be more than 15 degrees. For example, if the
temperature going into the air conditioner is 80 degrees, the
temperature coming out of the unit should be at least 65 degrees or
less. If the difference is 15 degrees or more there is probably no
cause for concern. If the temperature difference is less than 15
degrees you should check the following:
Check to make sure the air damper is closed. If it's open, it will bring in outside air and reduce the efficiency of the unit.
During
the winter season many people cover their air conditioners to protect
the unit from the weather. In the spring or summer they will sometimes
forget to remove the cover. If your unit has a cover on the outside
portion of the air conditioner remove the cover first.
The
condensing coils will always be on the "warm" side of the air
conditioner. That is, on the side that faces outside of the room to be
cooled. Air is drawn into the back of the air conditioner on the sides
through vent slots and is blown directly out through the condenser
coils. If the coils get clogged with lint, dust and dirt the cooling
system cannot provide the cooling necessary. To clean the coils it will
be necessary to remove the entire cover of the air conditioner or pull
it out of the wall to gain access to the coils. They can be cleaned by
blowing compressed air at them or by using a soft bristle brush to wipe
the dirt off. It is important to also clean any dirt or lint build-up
in the bottom of the air conditioner so the condensate water will be
picked up by the condensing fan slinger properly.
