Williams Comfort Products P321826 Vent Limit Switch

​The Williams Comfort Products P321826 Vent Limit Switch operates as a HVAC system component dedicated to use in Monterey Counterflow Top Vent Furnaces 250 and 500 Series models. The part operates as a safety monitor that automatically shuts down the system when the temperature reaches 220°F or higher to prevent overheating while maintaining operational safety. The part provides extended durability because its robust material construction lowers maintenance requirements. The system operates more efficiently and reliably when ventilation systems are maintained. This is to ensure both safety and optimal performance in HVAC systems.​
