Description

The Johnson Controls Y75AA-3 Flame Sensor Probe 1-1/4" works by sensing the presence of a pilot flame by spark rectification in which the ionized gas in the fire is used to complete an electrical circuit. This part provides a continuous signal to the ignition control unit, which enables the gas valve to be open only when a flame is present. The hardware is attached to the assembly directly, with the 1-1/4" tester tip being placed strategically in the flame path.

Step1: Shut off power and gas supply, then confirm the burner system is fully cool.

Step2: Remove the existing flame sensor and note wiring placement on the terminal.

Step3: Install the new flame sensor into the same bracket, ensuring correct flame exposure position.

Step4: Reconnect the terminal securely, avoiding loose or oxidized connections.

Step5: Tighten mounting hardware so the probe remains stable in the flame path.

Step6: Restore power and gas, then check flame detection and proper shutdown response.
