Carrier LA22ZA123 Blower Wheel–1/2" Bore 10-5/8" DIA

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 ...

Regularly inspect and clean the blower wheel to remove dust and debris buildup, ensuring efficient airflow. Check for imbalance or vibration that could indicate wear. Tighten mounting hardware and verify bore set screw security. Lubricate motor bearings if applicable.

• Wheel imbalance causing excessive vibration in HVAC operation.
• Dust buildup reducing airflow and efficiency.
• Loose set screw or mounting failure leading to slippage.
• Bearing noise or wear causing abnormal sound.
• Airflow inefficiency or reduced output performance.
