A functional silicon carbide ignitor typically reads between 40 and 90 Ohms at room temperature

The junction box and terminal block design are specific to Williams wall furnaces that utilize a safety circuit loop

How do I troubleshoot a pressure switch code

this polymer port seal ensures the integrity of the heat exchanger and prevents leaks that can lead to system pressure drops or scale buildup

it prevents the ignition sequence if proper venting or combustion air levels are not detected
