Installation Instructions
This ignitor is a replacement part. Refer to your appliance's specific service manual for detailed installation steps. The following are general guidelines:
- Power Disconnection: Ensure the main power supply to the appliance is completely disconnected before beginning.
- Access: Locate and access the existing ignitor within the appliance's burner assembly. This may involve removing access panels or covers.
- Removal of Old Ignitor: Carefully disconnect the electrical wires from the old ignitor. Unfasten any mounting screws or clips holding the ignitor in place and gently remove it. Note its orientation for correct replacement.
- Inspection: Inspect the mounting area and electrical connectors for any damage or corrosion. Clean as necessary.
- Installation of New Ignitor: Position the new Rheem SP12143 Ignitor in the same orientation as the old one. Secure it with the appropriate mounting hardware. Ensure the ignitor is not touching any metal surfaces that could cause a short circuit.
- Electrical Connection: Connect the electrical wires to the new ignitor's connector. Ensure connections are firm and correct.
- Reassembly: Reinstall any removed access panels or covers.
- Testing: Restore power to the appliance and test for proper operation. Observe the ignitor heating and the burner igniting.
Operation
The Rheem SP12143 Ignitor operates as part of an automatic ignition sequence. When the appliance calls for heat, the control board sends voltage to the ignitor, causing its silicon carbide element to heat up rapidly. Once the ignitor reaches a sufficient temperature (typically glowing bright orange), the gas valve opens, allowing gas to flow to the burner. The hot ignitor then ignites the gas. After successful ignition, the ignitor typically de-energizes, though some systems may keep it energized for a short period to ensure stable flame.
Maintenance
The Rheem SP12143 Ignitor is generally a sealed component and does not require routine user maintenance. However, periodic inspection during appliance servicing is recommended:
- Visual Inspection: During annual appliance maintenance, visually inspect the ignitor for cracks, discoloration, or signs of physical damage. A healthy ignitor should appear intact.
- Electrical Connections: Check that electrical connections to the ignitor are clean, tight, and free from corrosion.
- Cleaning: Do not attempt to clean the ignitor element with abrasive materials or chemicals, as this can damage it. If dust or debris is present, gently brush it off with a soft, dry brush or use compressed air.
- Replacement: If the ignitor shows signs of damage, fails to glow, or fails to ignite the burner consistently, it should be replaced by a qualified technician.
Troubleshooting
If your appliance is experiencing ignition issues, consider the following common problems related to the ignitor:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Ignitor does not glow. | No power to ignitor, faulty ignitor, or control board issue. | Check electrical connections. Test ignitor for continuity (if qualified). Consult appliance service manual or qualified technician. |
| Ignitor glows but burner does not ignite. | Insufficient gas supply, faulty gas valve, or ignitor not hot enough. | Verify gas supply. Check gas valve operation. Ensure ignitor is positioned correctly. Consult qualified technician. |
| Ignitor glows intermittently or weakly. | Failing ignitor or unstable voltage. | Replace ignitor. Check power supply. Consult qualified technician. |
| Ignitor is visibly cracked or broken. | Physical damage. | Replace ignitor immediately. Handle new ignitor with care. |
Note: For complex issues or if you are unsure about any step, it is highly recommended to contact a qualified HVAC technician or appliance service professional.
