indicated. In the event that the problem can not be corrected, service may be required.  

  

SERVICE SHOULD BE PERFORMED BY A QUALIFIED  

AIR CONDITIONING SERVICE TECHNICIAN 

 
 

PROBLEM: UNIT DOES NOT POWER UP 

CAUSE:   

Power interruption 

REMEDY: 

Check LCDI (on models with LCDI), and reset LCDI.  Check external power 

supply making sure that the disconnect is ON.  Check for blown fuses or tripped circuit 
breakers. Reset or replace if needed. 

 
PROBLEM: NO DISPLAY ON THERMOSTAT 

CAUSE:  

Faulty thermostat or faulty transformer 

REMEDY: 

Thermostat may be defective...remove and replace.  Transformer may 

be defective...remove and replace. 

 

PROBLEM: EVAPORATOR FAN RUNS BUT 
COMPRESSOR AND CONDENSER FAN DO NOT 
START 

 

CAUSE:  

Thermostat — setting may be too high.   

REMEDY:  

Make sure set-point is lower than room temperature. You should see a 

snowflake ”

” designating that the thermostat is calling for cooling. 

 

Note—there is a time delay for the compressor 

 

CAUSE: 

Thermostat—Loose wiring 

REMEDY:  

Examine the control unit for loose wires. Tighten any loose connections.  

 

CAUSE:  

Condensate Alarm—Check for Condensate Alarm Light. 

REMEDY:  

Check condensate level and empty tank if needed, or (if installed) 

check condensate pump and make sure pump is working properly. Confirm that there is 
no restriction in the drain line from the pump.   
 

CAUSE:  

High Pressure Cut-out—Check High Pressure Cut-out Switch.  

 

REMEDY:  

Press Reset and clear away any air flow obstructions to the condenser 

intake or condenser discharge.   
 

CAUSE:  

Voltage — Check power supply for voltage outside the range of 106-126 volts 

on the 115 Volt unit and  187-253 Volts on the 208/230 Volt unit. 

REMEDY:  

Have power checked by electrician and repaired. 

 

CAUSE: 

Compressor contactor open or burned.      

REMEDY: 

Replace contactor.
