This SPDT 120V relay features a 115/120 VAC coil with a 2000 Ohm DC resistance

What causes these coils to burn out

scaleplate

this fitting features long dryseal pipe threads that maximize clearance for flare nuts while providing a leak-proof seal even in high-vibration ACR applications

this component protects the heat exchanger from structural damage by interrupting the burner sequence if internal temperatures exceed safe operating parameters due to restricted airflow or blower failure
