The Lennox 49W66-Ignition Control Board designed to provide ignition and safety of the HVAC system. This control board is essential in ensuring that there is uniformity in the heating equipment. It controls the flow of gas and the time at which the spark is produced to ensure the proper functioning of the burner. It is designed to work with select Lennox furnaces and improves the system’s safety and efficiency. Then, for residential and light commercial use, it assists in preventing ignition failures and thereby eliminating system downtime.
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 ...
