York TG8S100C20MP11: 80% AFUE Single-Stage Gas Furnace Service
Annual flame sensor cleaning is the most cost-effective preventive maintenance step for the York TG8S100C20MP11. A flame sensor coated with oxidation from normal combustion deposits cannot confirm ignition to the control board, causing the furnace to attempt ignition, fail to sense flame, and lock out. Cleaning with fine steel wool restores function without replacement in most cases. The gas furnace repair help section covers TG8S100C20MP11 igniter testing, flame sensor cleaning, and inducer motor diagnosis.
Most Replaced Parts on the York TG8S100C20MP11
Hot Surface Igniter for the York TG8S100C20MP11
The hot surface igniter heats to incandescence to light the burner. A cracked or failed igniter produces a no-heat lockout on the first ignition attempt.
Flame Sensor for the TG8S100C20MP11
Annual flame sensor cleaning with fine steel wool is the most cost-effective preventive step. A sensor that cannot be cleaned should be replaced.
Control Board for the York TG8S100C20MP11
Read the LED fault code displayed on the board before ordering a replacement. The TG8S100C20MP11A and TG8S100C20MP11B revisions may share the same control board.
Inducer Motor for the TG8S100C20MP11
The inducer motor must pre-purge combustion gases before ignition. A failed inducer motor triggers the pressure switch and causes a no-heat lockout before ignition begins.
