A Vulcan Hart 00-851800-00032 Bulb Holder/Clamp keeps the thermostat bulb secure for steady temperature control and dependable performance.
The bulb holder/clamp secures the thermostat sensing bulb in the correct position so the control can read cabinet temperature accurately and regulate heat properly. Its construction matters because a stable, heat-tolerant clamp prevents bulb movement, poor contact or misalignment that could lead to inconsistent warming performance in compatible equipment.
The bulb holder/clamp may need replacement if the unit shows uneven temperatures, erratic heating cycles or thermostat readings that seem inconsistent during operation. Physical signs can include a loose, bent, cracked or corroded clamp and environmental signs may include heat exposure, vibration or moisture that could weaken its grip on the sensing bulb.
