Ensure the safety and efficiency of your heating system with this premium 3-inch high limit switch. Designed as a critical safety sensor for residential furnaces and HVAC units, the L290-30F control prevents equipment damage by monitoring internal temperatures. This switch is engineered to automatically interrupt power to the gas valve or heating element if the system exceeds the preset 290°F safety threshold, effectively preventing overheating and potential fire hazards. Once the temperature cools by 30°F, the switch resets to allow for normal operation. If your heater is cycling on and off too frequently or has shut down due to high temperatures, this high limit control is the ideal replacement part to restore reliable performance and peace of mind.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
