Trane CNT6194 Heat Control Board 24 V

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Heat control boards should be kept free from dust and moisture to ensure stable operation. Inspect wiring connections periodically for corrosion or looseness. Proper handling during service can prevent electrical damage and maintains accurate HVAC system performance.

• No heat output due to relay failure.
• Intermittent operation from loose wiring.
• Burnt components from voltage surge.
• Sensor miscommunication causing inaccurate control.
• Short cycling due to control board malfunction.
• Complete failure to power on.
