International Comfort Products 1186436 3/4HP ECM Blower Motor

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 ...

Inspect the blower motor regularly for dust buildup, loose wiring, and airflow restrictions. Keep the blower wheel and surrounding HVAC components clean to maintain efficient airflow. Check electrical connections and mounting hardware for wear or vibration damage.

• Motor fails to start or intermittently shuts off.
• Inconsistent or erratic blower speed control.
• Overheating during extended operation.
• Noisy or worn bearings.
• Reduced airflow output.
