Williams P323665 Thermal Cutoff L99H008 which is critical for theWhen you're troubleshooting a Williams wall furnace that won't kick on despite a healthy pilot, the Williams P323665 Thermal Cutoff is a primary failure point to inspect. This genuine OEM Williams furnace part serves as a critical high limit safety switch, designed to interrupt the electrical circuit if internal temperatures exceed safe operating parameters. Specifically calibrated with a 167C (333F) trip point, this thermal link provides non
