Indoor Blower Motor
The blower motor is responsible for moving warm return air over the evaporator coils. If the motor fails or operates below required CFM, the refrigerant inside the coils does not absorb enough heat to maintain a temperature above 32°F, leading to rapid ice accumulation. This ice eventually blocks all airflow, resulting in warm air discharge from the vents.

Blower Motor Run Capacitor
This component provides the necessary phase-shifted current to the blower motor's start winding. A degraded capacitor will result in a motor that either fails to start or spins at significantly reduced speeds, which fails to provide the necessary heat load to the evaporator coil, causing the refrigerant to flash off at a temperature that freezes the coil's condensate.

Thermal Expansion Valve (TXV)
The TXV regulates the flow of liquid refrigerant into the evaporator. If the internal sensing bulb loses its charge or the needle becomes stuck, it may 'hunt' or restrict flow excessively, causing an artificial pressure drop that lowers the refrigerant's boiling point below the dew point's freezing threshold.
