NORDYNE 632484R Nordyne Furnace Flame Sensor 632484R
NORDYNE 632484R Nordyne Furnace Flame Sensor 632484R
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)
Furnace/Boiler Fails to Ignite – The system may start but shut down quickly if the flame sensor doesn’t detect a flame.
Short Cycling – The burner turns on but shuts off after a few seconds.
No Flame Signal – The control board may lock out or display an error code (e.g., "flame failure").
Soot or Corrosion on Sensor – Visible buildup can impair functionality.
Intermittent Operation – The system works sometimes but fails at other times.
Troubleshooting the 632484R Flame Sensor
Power Off – Turn off the gas and electricity to the unit before inspection.
Visual Inspection
Check for cracks, corrosion, or soot on the sensor rod.
Ensure the sensor is properly positioned in the flame path.
Cleaning the Sensor
Use fine steel wool or emery cloth to gently clean the rod.
Avoid abrasive materials that could damage the sensor.
Testing Continuity
Use a multimeter to check for continuity (should read 0-5 μA when exposed to flame).
No continuity indicates a faulty sensor.
Check Wiring & Connections
Ensure wires are securely connected to the sensor and control board.
Look for damaged or frayed wires.
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
Turn Off Power & Gas Supply – Ensure safety before proceeding.
Remove Old Sensor
Disconnect the wire from the sensor.
Unscrew the sensor from the burner assembly.
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.
Reconnect Wiring
Attach the wire to the new sensor (ensure a tight connection).
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.
