This pack of five high limit control switches is a critical safety component designed for residential HVAC systems and forced-air furnaces. These thermal cutout switches monitor the internal temperature of your heating equipment to prevent hazardous overheating. Engineered for reliability, the switch automatically opens the electrical circuit when the temperature reaches a threshold of 240°F, effectively shutting down the burner or heating element. Once the system has safely cooled down to 155°F, the switch closes to allow for a reset and continued operation. Ideal for furnace repair and routine maintenance, these high-quality sensors ensure your heating system operates within safe thermal parameters, protecting both the appliance and your home from heat-related damage.
