Lennox 81L76 Control Board C2-3 is the central control unit of several Lennox HVAC devices and equipment, similar to a computer. It is involved in controlling essential system processes to achieve the better comfort and performance. This circuit board receives data from sensors located all over the system and it measures temperatures, fans’ RPM, and safety features. Accordingly, the control board obtains information that in turn provides signals to the compressor and blower motor to either increase or decrease their activity.

How to install an expansion valve for refrigeration?

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 ...
