  • Swap A and B heater output cables and RTD cables and see if issue follows. If so, replace RTD.

 

  • Check for loose heater element wires or loose green connector at TCM.
  • Confirm resistance of heater. Heater resistance should be 23-26 Ω. If out of tolerance, replace heater element.

 

  • Turn on the manual valve switch (MV), on the load center, and see if the valve shifts. If not replace solenoid.

 

  • Wait until operating temperature has been reached before spraying or recirculating.
