ECM Blower Motor and Module Kit
The EL296V utilizes a variable-speed ECM which is prone to failure in the power inverter section of the module. High static pressure from restricted filters can cause the internal components to overheat, leading to a catastrophic failure of the inrush current limiter (thermistor). When this fails, the motor cannot translate electrical energy into rotation, resulting in zero airflow.

Integrated Furnace Control Board
The IFC board acts as the central logic unit that sends the PWM (Pulse Width Modulation) signal to the blower motor. If the internal relay or the communication circuit on the board is damaged by an electrical transient, it will fail to send the start command to the blower. This results in the furnace completing its ignition sequence and then tripping on a high-limit safety because the blower fails to remove heat from the heat exchanger.

Blower Door Interlock Switch
This is a mechanical safety switch that breaks the 120V line voltage to the furnace if the blower compartment panel is not perfectly flush. If the switch housing is cracked or the mounting bracket is bent, the furnace will lose all primary power. This prevents the blower from energizing even if the thermostat is calling for fan or heat.
