The Robertshaw 10-028 is a precision-engineered LP gas orifice designed for specific pilot burner applications requiring a

Built to handle high-amp HVAC circuits

Durable Construction: Built with robust materials to withstand heat and moisture typical of furnace burner compartments

Look for physical bulging at the top of the canister or use a multimeter to check if the capacitance has dropped more than 10% below the 55 microfarad rating

replacing a failed diaphragm with this genuine 632491R Nordyne part restores the critical safety loop between the draft inducer and the ignition control board

Lennox 24L26 Limit Switch The Robertshaw 10-028 is aThe Lennox 24L26 Limit Switch is a critical OEM furnace safety control engineered for high static environments and precise thermal monitoring. This automatic reset limit switch is designed to protect the heat exchanger and blower assembly from thermal runaway by interrupting the burner circuit when temperatures reach the 200F high limit trip point. Once the plenum cools to the 160F reset temperature, the switch automatically closes to resume normal
