TROUBLESHOOTING GUIDE
Neither fan motor not
compressor operate
In sufficient cooling
No cooling
1) Check power supply switch or
plug and measure the voltage
1) Fuse open or circuit braker
open
1) If fuse or breaker are normal,
ask the power supply
company for check.
2) Plug disconnected
3) Plug connected properly but
contact defective.
2) Connect properly.
1) Knob position not properly
adjusted
3) Change power supplym cord
with plug.
1) Move thermostat knob to a
higher number (toward 10).
2) Defective thermostat 2) Replace
2) Change compressor
2) Outside air too high temp.
1) Equipment defective if no
temp. difference
3) Air conditioner normal but
heat leak excessive
1) Change or repair defect
2) Improve ventilation, avoid
sunshine
3) Calculate cooling load and
change or remove heat
source
1) Change capillary tube
2) Check for gas leak and
repair, recharge
1) Capillary tube restricted
2) Gas leak
1) Gas leak
2) Compressor defective
2) Check if temp.difference
between inlet and outlet air of
indoor unit is over 14˚F
1) No temperature difference
between discharge pipe and
suction pipe of compressor
3) Check indoor exchanger
inlet/outlet piping temp.
Sweat is less than half of coil
or frost sticks to capillary tube
2) Check air filter
1) Check thermostat
Air filter clogged Clean
3) Check for a high heat source
4) Check doors and windows
5) Check if condenser and evaporator are clean
6) Check if any object is restricting heat radiation from the
condenser.
7) Undersized air conditioner
8) Sealed system
Remove the added heat source
Windows and doors must be
kept closed
Clean them with steam cleaner
or another method
Remove the object or move the
air conditioner
Use Cooling Load Estimate
Form (Refer to page 16).
