Product Details

Description

The 3-inch Control Limit Switch L250-30F is a critical safety component designed for residential gas furnaces and HVAC heating systems. This high limit control switch acts as a thermal safeguard, monitoring the internal temperature of the heat exchanger to prevent overheating. When the air temperature reaches the fixed 250°F threshold, the switch automatically opens the electrical circuit to shut down the burner, protecting the appliance and your home from potential damage. Once the temperature drops by 30°F to a safe level (220°F), the switch resets, allowing for normal operation. If your furnace is short-cycling or failing to produce heat, a faulty high limit sensor may be the cause. This reliable replacement part features a 3-inch insertion probe, making it an essential component for maintaining safe and efficient furnace performance.
