Williams Comfort Products P323366 Limit Switch L240°-40°F

Williams Comfort Products P323366 Limit-Switch L240°-40°F is a temperature-sensitive equipment made to keep HVAC systems in wall and direct-vent furnaces safe. This bimetallic auto-reset switch keeps track of furnace temperatures and shuts off power, if it senses heat above 240°F to stop overheating and harm. After the unit has cooled to a safe point, it automatically resets. Because it is used in many residential and light commercial HVAC systems, it helps make them safer and last longer by controlling temperature consistently. This helps keep furnaces safe and their parts protected, so it’s a better choice for efficient HVAC system performance.
