Description
The Armstrong Furnace R42936-001 is a factory-specified discharge thermostat (T-Stat) designed to protect your furnace from overheating conditions at the discharge air point. Engineered as a direct OEM replacement for compatible Armstrong Furnace systems, this limit control helps ensure safe, reliable furnace operation season after season.
How It Works
The L250-110F designation identifies the operating parameters of this discharge thermostat. When discharge air temperatures reach the upper limit, the thermostat opens the circuit to shut down the heat source, preventing damage to the heat exchanger and surrounding components. Once temperatures fall to the reset point, the thermostat automatically restores normal operation.
