SOURCE: Frigidaire air conditioner - no cool air coming out.
if you used it alot, i would check it for freon.
checkthe air filter, make sure it's not dirty.
check the front panel, make sure there's no "ice/frost" in the unit.
SOURCE: Error code of E4 on Dometic HP air conditioner ??
16. SYSTEM RESET
a. Turn the ON/OFF switch to “OFF” position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to “ON”.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released.
c. When a dip switch is turned on or off after initial configu
ration, a system reset will need to be done before the
Comfort Control CenterTM will recognize the updated selection. Try this. This is for the five button thermostat. Did you check the dip switches to be sure the proper ones are turned on? I need to know which stat you have 4 or 5 button. I have trouble shooting for both.
If you notice reset needs to take place after a dip switch is turned on or off. The dip switches are on the circuit board. You need to drop the lower cover. the dip switches will read in this order #1 heat strip/ #2 zone2/#3zone3/ #4 zone4/#5 furnace/#6 differential/#7stag/#8 gen start. Check this out and be careful. Turn off the stat to change dip switches. On will be toward the description. If you don't have remote start gen set the dip should not be on. If you dont have a Zone 3 the dip should not be on, etc.
Any questions feel free to post back

Remove the front cover of the unit to expose the cooling coil. Put the unit on and observe if there will be formation of frost (ice) on the coil. If there's frost formation, the common cause is dirty cooling coil. Have it cleaned using an alkali base coil cleaner. If the coil is clean, then the problem is the fan motor. It might be turning slow due to copper loss. Have it replaced.
SOURCE: Air conditioner isn't cooling the room
hi there,
insufficient cooling have several reason,most common factor is low freon charging due to service factor,defective thermostat control,dirty evaporator and condenser fin,try to check the current rating using ammeter clamp tester if the rated current read in tester below the rated current on tag(compressor)
you need to charge freon,if the fin and evaporator is dirty need to ve clean,if the thermostat is not functioning replace thermostat.
also consider the main defective if the aircon is running chck the compressor if it is running by touching the tip of screw driver to the top body of compressor you can feeel vibration,if compressor is not running yo don't have cooling effect only blowing of air.on repairing this this should be done by a certified aircon technician,have a nice day fix my rate,thank you very much.

Welcome to FixYa
Check the Following
Is your filter clean? Look and the evaporator in the inside unit. Is it frosted up? Do you have condensation water in the pan? Go to the outside unit and feel the air coming out of the fan. Is it warm? Now feel the 2 copper pipes coming out of the unit. Is the small one warm or hot? Is the larger one cool ? Is there moisture on it?
Air conditioner runs but
doesn't cool at all
If the airflow is good and the air coming out is not cold, your
home air conditioning problem may be a temporary problem - your coils
may have frozen. Turn the unit off for an hour to let them thaw, then
try again. If cold air is now present, freezing coils were the problem; if the
problem recurs soon after turning on, you may need to replace the coils. Again,
call a pro. If you have ceiling vents in upstairs rooms and the air flowing
from them is consistently warm, you probably have leaky or poorly insulated
ductwork in your attic. See my Attic ceiling insulation page for more
information on insulating ductwork that runs through attics.
Another likely home air conditioning problem if you have good
airflow but no cooling is that the breaker to the outside unit is shut
off, which, depending on the installation, can either cause the air
conditioning system to not run at all, or to appear to be running but not
provide any cooling. If you can hear the compressor fan running outside, the
breaker is on, but if the outside unit is silent the outside breaker may be
off. If switching it on does not solve the problem, look for the high pressure cut out on the
condenser and try resetting that.
