Common Questions & Professional Insights

How do I know if the Fenwal 22-100001-067 needs replacement?
If the burner ignites but shuts down after a few seconds, or if you are measuring a flame signal below the manufacturer's recommended microamp threshold, the sensor is likely fouled or failing. Cleaning may provide a temporary fix, but replacement is the professional standard for long-term reliability.

Is the 22-100001-067 compatible with other ignition modules?
This sensor is specifically designed for systems utilizing Fenwal ignition controls. Always verify the part number against the equipment's service manual to ensure proper signal impedance and terminal connection compatibility.

What causes a flame sensor to fail?
The most common causes are carbon buildup (soot), high-temperature oxidation of the probe, or a cracked ceramic insulator which causes the signal to short to ground.
