Problem: Air conditioner does
not operate, or turns off and on sporadically.
Background: Regular care and light maintenance of
compact room air conditioners helps assure longer ser vice
life and lower operating costs. Most important for maximum
cooling is the regular cleaning of the permanent, washable
filter, which removes dust, lint, and other air borne
particles. It should be checked at least every 30 days of
operation. The unit should also be inspected annually by
yourself or a technician.
What to do: If the air conditioner is not
operating, first check to see if its cord is properly
plugged into the outlet. Check the main electrical panel
to see if a fuse has blown, or if a breaker has tripped.
If this is not the problem, turn on a light to find out if
the local power supply has failed. If it has not, check to
see if the air conditioner has been accidently turned off.
If the air conditioner operates intermittently (turns off and on)
or does not cool the room, check to see if anything is
blocking the front of the unit. Close the doors to
adjoining rooms and if the thermostat is set at less than
the coldest position, turn it to that position. Also check
the filter and coils for dirt accumulation. Be aware that
if the air conditioner is being fed power through a long
ex tension cord, it may not be getting enough power to
Special advice: You should be able to remove the
permanent, washable- type filter, and clean it by using a
vacuum cleaner. If the filter is extremely dirty or
clogged, clean it in warm water with a normal amount of
detergent and dry it before replacing. Plastic parts of
the unit may also be cleaned with a soapy water solution,
using a soft cloth.
Helpful hint: Every
year the coils and condensate water passages should be
inspected and cleaned, if necessary. Although the
compressor is the hermetically sealed type and the fan
motor is likely to be permanently oiled, these parts
should also be checked annually to ensure that they are in
good operating condition.
