DRAIN PAN VALVE 

During the cooling mode of operation, condensate which  

collects in the drain pan is picked up by the condenser fan  

blade and sprayed onto the condenser coil. This assists 

in cooling the refrigerant plus evaporating the water. 

During the heating mode of operation, it is necessary that 

water be removed to prevent it from freezing during cold 

outside  temperatures.  This  could  cause  the  condenser 

fan blade to freeze in the accumulated water and prevent 

it from turning.  

To provide a means of draining this water, a bellows type 

drain valve is installed over a drain opening in the base 

pan. 

This valve is temperature sensitive and will open when 

the  outside  temperature  reaches  40°F.  The  valve  will 

close gradually as the temperature rises above 40°F to 

fully close at 60°F.  

Testing  of  the  heating  elements  can  be  made  with  an 

ohmmeter or continuity tester across the terminals after 

the power wires have been removed. Test the limit switch 

for  continuity  across  its  input  and  output  terminals.Test 

below the limit switch’s reset temperature.

All  heat  pumps  and  electric  heat  models  are  equipped 

with a heating element and a limit switch (bimetal ther-

mostat). The limit is in series with the element and will 

interrupt the power at a designed temperature.

 

Should the blower motor fail, filter become clogged or air-

flow be restricted etc., the high limit switch will open and 

interrupt the power to the heater before reaching an un-

safe temperature condition.
