Additional Features:
The Roberts-Gordon 90439300 Automatic Ignition Flame Probe serves as the dedicated flame sensing component for a broad lineup of Roberts-Gordon gas-fired heating equipment. The extended stainless steel sensing rod, supported by a high-temperature white ceramic insulator and a stamped steel mounting flange with a single fastener hole, positions the probe tip well into the burner flame path while keeping the conductive element fully isolated from the heater chassis and surrounding metalwork. Once installed, the probe operates on the principle of flame rectification, passing a small DC current through the ionized gases of an active flame to signal the ignition control that combustion is established, while any loss of that signal prompts an immediate fuel shutdown to protect the appliance and confirm safe, dependable burner performance across every listed model.
