this HVAC safety switch is calibrated to provide high-limit protection by breaking the electrical circuit to the gas valve or ignition control if internal temperatures exceed factory safety thresholds

Enhanced Thermal Dissipation: The oil-filled oval metal case design efficiently manages internal heat for stable performance during high-load cycles

Unlike a standard fuse

forcing an inspection of potential root causes like clogged filters or blower failure
