This component is technically identical to MCS-G

preventing the control board from seeing the proper microamp signal

providing reliable over-temperature protection in high-static or restricted airflow conditions

any cracks in the porcelain insulator or significant pitting on the rod require an immediate replacement to ensure reliable rectification and prevent safety shutdowns

High-Temperature Durability: Constructed with materials rated for the intensive heat cycles of gas-fired water heaters

White-Rodgers 90-294Q Relay This component is technically identicalThe White Rodgers 90 294Q Relay is a heavy duty, Type 84 enclosed fan relay engineered for versatile switching in multi speed blower systems, resistive loads, and general purpose HVACR applications. This SPDT 120V relay features a 115 120 VAC coil with a 2000 Ohm DC resistance, drawing a nominal 25 mA for high efficiency operation. Designed for rigorous field use, the unit provides a compact, fully enclosed housing that protects internal switching
