TROUBLESHOOTING
CAUTION
If any of the following conditions occur, stop the air conditioner immediately, turn off the main power switch and contact the
dealer.
• The indicators flash at short intervals (5 Hz). Reset the circuit breaker 2 to 3 minutes after the power main switch is turned
off.
Despite the resetting operation, the indicators still continue turning on and off.
• The main power fuse often blows, or the circuit breaker is often activated.
• Foreign matter or water has fallen inside the air conditioner.
• Any other unusual conditions are observed.
Before asking for servicing or repairs, check the following points.
Recheck
Inoperative
• The power main switch is turned off.
• The circuit breaker is activated to cut off the power supply.
• The main power fuse has blown.
• The electric current has stopped.
• The batteries in the remote controller used up.
• The ON timer is set.
• As a protective mechanism for the air conditioner, it does not operate for 3 minutes
immediately after restarting operation or turning on the main power.
Poor cooling or heating performance
• The air inlet or outlet of the outdoor unit is blocked.
• Doors or windows are opened.
• The air filter is clogged with dust.
• The louver is not at the correct position.
• The fan speed is set to low.
• The air conditioner is set
to the DRY or SLEEP MODE.
• The temperature setting is too high (during cooling operation).
• The temperature setting is too low (during heating operation). (heat pump models)

It sounds to me that the air con is on auto fan, as the room gets hotter or colder the fan will slow down and stop. keep the fan on low,med or high fan speed

Most possible reason in this case is defective compressor(it overheats),or not enough freon in the system. Solution 1.change compressor;2.Recharge the system with freon.

Lift indoor unit cover and remove DC wire from display sensor. After 3 minutes again plug it and close the door. Now you try with your remote. If still problem, check your remote through cell phone camera by pressing any button in remote. If ultra light is visible thr' camera, remote is o.k. If remote is o.k, repair/replace PCB. Thanks.

E-5 -Comms Error, check your wiring, remove external pumps. Split/Multi - check volts from terminal N to 3 = 0 - 65 Vdc, Multi V - 4 Vdc terminals 3 and 4

It indicates afault within the unit. Give Carrier a call and get it serviced.

Hi

Try to reset the unit by disconnecting the power supply for 10sec. and operate the unit. If it wont work replace your Room Air and Coil Thersmistor or test the thersmistor with mulitester. The resistance reading of thermistor is 10 kilo ohms @25deg. C room temp. If it is shorted or open the unit wont operate.

Hope this can help :)
