Dryer Thermal Fuse (High Limit)
The thermal fuse is a safety device located on the burner funnel that permanently opens the electrical circuit to the gas valve if temperatures exceed a specific threshold. This typically occurs due to a restricted exhaust vent or lint build-up, causing heat to back up into the cabinet. When it fails, the dryer will continue to tumble via the motor circuit, but the burner will never receive the signal to ignite.

Gas Dryer Igniter
The igniter is a fragile silicon component that glows at high temperatures to ignite the gas. Over years of operation, the material undergoes thermal expansion and contraction, leading to micro-fractures that eventually break the circuit. If the igniter is cracked, the flame sensor will never detect the required heat to open the gas valve, resulting in no combustion while the drum spins.

Gas Valve Solenoid Coil Set
These electromagnetic coils are responsible for physically lifting the plungers inside the gas valve to release fuel. Heat from the burner can cause the internal copper windings to short-circuit or break over time. In this failure mode, the igniter may glow properly, but the solenoids fail to open the valve, preventing the dryer from heating.
