Why is my Thermal Care RA Temperature Controller overheating and overcooling?

  If your Thermal Care Temperature Controller is alternating between overheating and overcooling, or rapidly cycling from heat to cool, several factors could be at play. First, check the water flow by examining connectors and increasing their size if needed. For systems with many or long hoses, shorten hose runs and maximize hose size to reduce pressure drop. If quick disconnects with check valves are present, remove the check valves to decrease pressure drop. Also, inspect the thermocouple connection and replace it if necessary. Finally, consider replacing the controller if the microprocessor has failed.

  If your Thermal Care Temperature Controller isn't heating properly, start by checking the solenoid valve. Try flushing it out by adjusting the Set Point up and down several times to open and close it. If that doesn't work, stop the unit, turn off the power and water, and disassemble the solenoid valve for cleaning or replacement. Also, inspect for leaks and replace any faulty valves. Have a qualified electrician verify the functionality of the immersion heater and/or heater contactor, replacing any defective components. Consider replacing the controller if there is a microprocessor controller failure, replacing the thermocouple if it has failed, replacing the heater if it has failed, or replacing the heater contactor if it has failed.
