Description 

Power Module Heat Exchanger Too Hot 

  • Occurs if the power module heat exchanger temperature gets above 105C. 
  • Since activating the heating element is the far most heat applying solid state switch, activating is bypassed to reduce temperature. 
  • Indicates: 
  • Poor cooling to the back side of the control box. 

Corrective Action 

  • Check for blocked air flow to the back side of the control box. 
  • Ambient temperature might just be high.
