Flame Sensor
The flame sensor is a stainless steel rod that monitors the flame through rectification, where the flame itself completes an electrical circuit. Over several heating seasons, oxidation or silica from combustion air coats the rod, insulating it and preventing the control board from 'seeing' the flame. Replacing this component restores the safety feedback loop required to maintain the gas valve signal after the initial ignition window.

High Limit Safety Switch
This bimetallic safety device is designed to open the electrical circuit to the gas valve if the heat exchanger exceeds its maximum safe operating temperature. If the furnace runs for a short period before shutting off, it is often due to the limit switch 'tripping' because of insufficient airflow caused by a clogged filter or a failing blower motor. Replacing the switch is necessary if the internal bimetallic disc has weakened or warped from repeated thermal stress.

Condensate Trap Assembly
As a 96% AFUE unit, the GMVC96 produces acidic condensate during the combustion process. If the internal trap or drainage lines become clogged with sediment or biological growth, water backs up into the secondary heat exchanger or collector box. This creates a pressure imbalance that causes the pressure switch to open, immediately cutting power to the ignition circuit to prevent exhaust backup or internal flooding.
