Description
The Advanced Distributor Products (ADP) 76716500 is an L190-30F high-limit switch engineered to protect furnaces and air handlers from dangerous overheating conditions. When supply-air temperatures exceed the set point, this limit switch interrupts the burner circuit, preventing heat exchanger damage and ensuring safe system operation. Once temperatures fall back within the safe operating range, the switch automatically resets, restoring normal heating function.
