ECM Condenser Fan Motor
The YXT series uses a brushless DC motor with an integrated inverter board. The motor's internal control module often suffers from dielectric breakdown of the capacitors or MOSFET failure due to heat dissipation issues or voltage transients. This results in a complete loss of commutation, meaning the motor will not initiate rotation even when line voltage and communication signals are present.

Outdoor Control Board
This board generates the Pulse Width Modulation (PWM) signal required to command the ECM fan motor's speed. If the communication circuit or the dedicated fan relay on this board fails, the motor remains in a high-impedance standby state. This is a common point of failure following electrical surges or moisture-induced corrosion on the low-voltage pins.

Compressor Contactor
The contactor acts as the primary mechanical switch for high-voltage power to the outdoor unit's components. Over time, the silver-plated contacts can become pitted or carbon-fouled (arcing), creating an open circuit that prevents the fan motor and compressor from receiving the necessary voltage to energize.
