FAULT – Unit displays CF, Audio alarm fails to clear on start up or while operating.

CAUSE – External Condensate Tank is full. Condensate bypass jack or condensate float switch jack is not installed or not positioned correctly. Water level switch is engaged.

SOLUTION – If applicable, empty the external tank.  Make sure thank is upright and level. Unplug bypass / tank plug to assure stable connections. System is set to automatically reset when the fault condition is corrected.

FAULT – Unit Displays CP and Audio alarm is sounding during start up or while operating 

CAUSE – Microprocessor board has detected high water level in the condensate pump. 

SOLUTION – Inspect the condensate pump for over flow, then check the condensate line for clogs or crimping. Resets automatically upon fault correction, or call 1-800-KWIKOOL if the problem persist.

FAULT – Display Reads HP and Audio Sounds at Start Up or While Operating

CAUSE – Microprocessor board has detected high pressure. The High Pressure switch is likely tripped.

SOLUTION – High pressure is normally caused by reduced condenser air flow. Look for duct restrictions. Check for condenser air system ventilation.  Look at the condenser motors and/or blowers for proper operation. Finally, manual reset is located next to the power cable.

FAULT – Displaying 32 and Unit Will Not Cool

CAUSE – The temperature sensor is not connected to the microprocessor. There is a temperature Sensor malfunction.

SOLUTION – Call 1-800-KWIKOOL for instructions.

FAULT – Displaying 32 and Unit Will Not Cool

CAUSE – The temperature sensor is not connected to the microprocessor. There is a temperature Sensor malfunction.

SOLUTION – Call 1-800-KWIKOOL for instructions.

FAULT – Supply air flow is limited, and / or water is dripping from the front of the system

CAUSE – Supply or return air is blocked or restricted, and or the evaporator coil is freezing. 

SOLUTION – Verify the supply and return air are not blocked. Turn the system off in order to thaw the check the air filter for blockage. Replace filter if needed.

FAULT – Condensate Not Pumping

CAUSE – Water is below pumping  level, external line restricted, line installed with too high of lift.

SOLUTION – Reservoir fills, and then pumps. Check for line crimping or restrictions and proper line run height. Refer to the user guide Section V: Built in Safeguards.

FAULT – Evaporator Coil is Freezing

CAUSE – Low or restricted air flow. Undersized capacity, unit constantly on, unable to achieve set point. Low return air temperature out of factory specifications. Evaporator door open, mechanical system malfunction.

SOLUTION – Direct supply return air to area of highest heat load, check for blocked air flow from the supply air, replace air filters, adjust set point to allow the unit to cycle, add another Kwikool® system or larger capacity model, close evaporator compartment door, inspect supply air blower for worn condition or breaking, Install service gauges to view pressures.

FAULT – Control Box Chatter or Hum During Operation

CAUSE – Incoming source power is poor or low voltage component is faulty.

SOLUTION – Check for proper voltage selection. Call 1-800-KWIKOOL for instructions.

FAULT – 99 Flashes On Display

CAUSE – Ambient room temperature over 99 degrees F.

SOLUTION – Unit is working properly. When the temperature in the room lowers, the 99 code will stop flashing.

FAULT – 60 Flashes On Display

CAUSE – Ambient room temperature under 60° F.

SOLUTION – Limits of unit have been reached. Operating temperatures  65° – 105°F.

FAULT – Power is supplied but control is blank 

CAUSE – Low voltage circuit is not engaged.

SOLUTION – Inspect the power breaker and verify that there is power getting through to the connector. Call 1-800-KWIKOOL for instructions.

FAULT – Unit Displays LP, Audio alarm is sounding during start up or while operating

CAUSE – Microprocessor board has detected low pressure. This alarm might cycle on and off.

SOLUTION – Check air filter and replace if dirty. Make sure nothing is blocking the filter inlet. Check for icing on coil. Resets automatically when fault condition is corrected. 

FAULT – Display Flashing F/C System is ON but Does Not Supply Conditioned Air 

CAUSE – System is in time out. One of three things.  Either control is above room temp; adjusted out of operating parameters, or not in the correct operational MODE.

SOLUTION – Wait 2 minutes, review System Operations guide.

FAULT – Display Flashing F/C, System is ON, Microprocessor Resets Time Delay When Compressor Attempts Start

CAUSE – Microprocessor board detects voltage drop below operating parameters.

SOLUTION – Confirm the integrity of your power source, by inspecting size and length of the power extension cable. Be sure you are using a dedicated circuit.

FAULT – System Trips Breaker on Start Up

CAUSE – Incoming power is incorrect, breaker is undersized or faulty, and or power cable is either long or too short.

SOLUTION – Verify the circuit and power cable is within the systems specifications, consult with your electrician or Call 1-800-KWIKOOL.

FAULT – System Cools, however, the Condenser Discharge Air Exhaust Fan is Revving, and/or the Condenser Discharge Fan is Intermittent.

CAUSE – This is the normal operating condition and especially when operating in low temperatures. 

SOLUTION – No action is required.
