NORDYNE 632484R Nordyne Furnace Flame Sensor 632484R

Brand: NORDYNE

The 632484R Nordine Flame Sensor is a critical component in gas-fired heating systems, ensuring safe operation by detecting the presence of a flame. Below are the symptoms of a faulty sensor, troubleshooting steps, and installation instructions.


Symptoms of a Faulty Nordine Flame Sensor (632484R)

  1. Furnace/Boiler Fails to Ignite – The system may start but shut down quickly if the flame sensor doesn’t detect a flame.

  2. Short Cycling – The burner turns on but shuts off after a few seconds.

  3. No Flame Signal – The control board may lock out or display an error code (e.g., "flame failure").

  4. Soot or Corrosion on Sensor – Visible buildup can impair functionality.

  5. Intermittent Operation – The system works sometimes but fails at other times.


Troubleshooting the 632484R Flame Sensor

  1. Power Off – Turn off the gas and electricity to the unit before inspection.

  2. Visual Inspection

    • Check for cracks, corrosion, or soot on the sensor rod.

    • Ensure the sensor is properly positioned in the flame path.

  3. Cleaning the Sensor

    • Use fine steel wool or emery cloth to gently clean the rod.

    • Avoid abrasive materials that could damage the sensor.

  4. Testing Continuity

    • Use a multimeter to check for continuity (should read 0-5 μA when exposed to flame).

    • No continuity indicates a faulty sensor.

  5. Check Wiring & Connections

    • Ensure wires are securely connected to the sensor and control board.

    • Look for damaged or frayed wires.

  6. Flame Rectification Test

    • A proper flame should produce a small DC current (microamps).

    • If the reading is below 1 μA, the sensor may be faulty.


Installation Instructions for 632484R Nordine Flame Sensor

  1. Turn Off Power & Gas Supply – Ensure safety before proceeding.

  2. Remove Old Sensor

    • Disconnect the wire from the sensor.

    • Unscrew the sensor from the burner assembly.

  3. Install New Sensor

    • Insert the new sensor into the mounting hole and secure it with the appropriate screw.

    • Ensure the sensing rod is properly aligned in the flame path.

  4. Reconnect Wiring

    • Attach the wire to the new sensor (ensure a tight connection).

  5. Power On & Test

    • Restore power and gas supply.

    • Start the system and verify proper flame detection.

    • Check for error codes or lockouts.


Additional Tips

  • Annual Maintenance – Clean the flame sensor during routine HVAC servicing.

  • Avoid Oily Residues – Do not touch the sensor rod with bare hands (oil can interfere with detection).

  • Use OEM Parts – Replace with genuine Nordine parts for reliability.

If issues persist after replacement, check the control board, gas pressure, or grounding issues.
