Lochinvar & A.O. Smith 100290352 Limit
The Lochinvar & A.O. Smith 100290352 Limit Switch is a critical safety component designed for high-performance hydronic and domestic hot water systems. This 220-degree high limit switch acts as a primary fail-safe, monitoring internal temperatures to prevent thermal runaway. Engineering specifications confirm this is a manual reset limit switch, requiring a technician's physical intervention to restore operation after a trip—a vital feature for diagnosing the root cause of overheating. Whether you are servicing a Lochinvar Power-fin boiler or an A.O. Smith industrial water heater, this genuine OEM part ensures the system maintains operational integrity without compromising safety. Professionals rely on the 100290352 spill switch functionality to protect the heat exchanger from damage caused by restricted flow or excessive scaling. Integrating this HVAC high limit control into your maintenance routine reduces the risk of catastrophic equipment failure and ensures compliance with factory safety standards.
Key Benefits:- Precise 220°F Trip Point: Engineered for accurate thermal response to stop the heating cycle the moment safe thresholds are exceeded.
- Manual Reset Mechanism: Forces a system inspection following a high-heat event, ensuring that underlying issues are addressed by a contractor.
- OEM Compatibility: Designed specifically for use with high-capacity Lochinvar and A.O. Smith units, ensuring a perfect fit and reliable electrical continuity.
- Rugged Construction: Built to withstand the high-ambient conditions found in commercial boiler rooms and mechanical spaces.
- Which models use the 100290352? This part is commonly found in Lochinvar Power-fin and Copper-fin II models, as well as various A.O. Smith commercial water heaters requiring a 220-degree rollout or high-limit safety.
- Can I bypass this switch for testing? Jumpering a manual reset high limit is strictly prohibited during normal operation; it should only be done briefly by a licensed technician to verify circuit continuity.
- Why does my limit switch keep tripping? Frequent tripping often indicates a pump failure, air in the lines, or excessive mineral buildup in the heat exchanger causing localized overheating.
