Always verify static pressure and airflow velocity before assuming the switch itself is defective

flame sensor troubleshooting often begins when a unit short cycles or fails to prove flame within the standard 4-second ignition window

Replacing the ICP furnace inducer housing ensures the combustion air blower maintains the precise static pressure required for safe venting and optimal heat exchanger performance

this is a "drop-in" solution that eliminates the risk of flame failure codes or improper ignition sequences associated with non-spec components
