Secondary Heat Exchanger Service Kit
In condensing furnaces, the secondary heat exchanger can suffer from laminate delamination or sediment buildup that restricts the flow of flue gases. This restriction creates positive backpressure within the combustion chamber, preventing the venturi effect from drawing the flame into the heat exchanger cells and causing it to 'roll out' into the burner compartment.

Inducer Motor Assembly
The inducer motor is responsible for creating the negative static pressure required to pull combustion air through the burners and heat exchangers. If the motor's RPMs drop due to bearing resistance or if the centrifugal blower wheel is damaged, the resulting decrease in draft allows flames to spill out of the burner intake.

Flame Rollout Limit Switch
This is a thermal safety device designed to open the electrical circuit when it detects excessive heat outside the combustion chamber. While often a secondary symptom of the heat exchanger failure, the switch itself can become hypersensitive or fail to reset after a thermal event, necessitating replacement to restore the safety monitoring loop.
