Key Features:

• Ignition Type: Direct Spark
• Element Material: Kanthal
• Termination: 1/4 inch quick connect

4. Setup and Installation

This ignitor is a replacement part. Refer to your specific furnace or HVAC system's service manual for detailed installation instructions and diagrams. The following steps are general guidelines.

Pre-Installation:

1. Verify that the Rheem Protech 62-24164-01 is the correct replacement part for your appliance model.
2. Gather necessary tools, which may include screwdrivers, wrenches, and electrical testers.
3. Ensure the work area is well-ventilated and free from combustible materials.

Installation Steps:

1. Disconnect Power and Gas: Locate the main electrical disconnect for the furnace and turn it off. Close the manual gas shut-off valve to the furnace.
2. Access Ignitor: Open the furnace access panel. Identify the location of the existing ignitor. It is typically near the burner assembly.
3. Remove Old Ignitor: Carefully disconnect the electrical wiring from the old ignitor. Unfasten any mounting screws or clips holding the ignitor in place and remove it. Note its orientation for correct installation of the new part.
4. Install New Ignitor: Position the new Rheem Protech 62-24164-01 ignitor in the same orientation as the old one. Secure it with the mounting screws or clips.
5. Connect Wiring: Connect the 1/4 inch quick connect termination of the new ignitor to the corresponding wiring harness. Ensure a snug and secure connection.
6. Restore Power and Gas: Close the furnace access panel. Reopen the manual gas shut-off valve and restore electrical power to the furnace.
7. Test Operation: Initiate a call for heat from your thermostat to verify proper ignition and furnace operation. Observe the ignitor's function.

5. Operating Principles

The Direct Spark Ignition (DSI) system operates by sending a high-voltage electrical spark directly to the main burner to ignite the gas. When the thermostat calls for heat, the furnace control board initiates a sequence:

• The inducer motor starts to clear any residual gases.
• The pressure switch closes, signaling the control board that airflow is established.
• The gas valve opens, allowing gas to flow to the burners.
• Simultaneously, the DSI ignitor receives power and generates a spark across its electrodes, igniting the gas.
• A flame sensor confirms ignition, and the main blower fan activates to distribute heat.

The Rheem Protech 62-24164-01 ignitor is the component responsible for generating this crucial spark.

6. Maintenance

Regular inspection and cleaning of the ignitor can help ensure reliable operation of your heating system. Always disconnect power and gas before performing maintenance.

• Inspection: Annually, or if ignition issues occur, visually inspect the ignitor for cracks, carbon buildup, or corrosion on the electrodes.
• Cleaning: If carbon buildup is present, gently clean the ignitor electrodes using a fine-grit emery cloth or a non-abrasive pad. Avoid using metallic tools or harsh chemicals that could damage the Kanthal element.
• Replacement: If the ignitor shows signs of significant wear, damage, or fails to spark consistently after cleaning, it should be replaced.

7. Troubleshooting

If your furnace is experiencing ignition problems, the ignitor may be a contributing factor. Always ensure power and gas are supplied to the unit before troubleshooting.

Common Symptoms of a Faulty Ignitor:

• Furnace attempts to ignite repeatedly but fails to light the burner.
• No spark is visible at the ignitor electrodes during the ignition sequence.
• The ignitor element appears cracked, broken, or heavily corroded.

Troubleshooting Steps:

1. Check for Power: Ensure the furnace is receiving electrical power.
2. Inspect Ignitor: With power and gas disconnected, visually inspect the ignitor for physical damage or excessive carbon buildup. Clean if necessary (refer to Maintenance section).
3. Verify Connections: Ensure the ignitor's electrical connections are clean and secure.
4. Consult Furnace Manual: Refer to your furnace's specific troubleshooting guide for diagnostic codes or further steps related to ignition failure.
5. Professional Assistance: If the problem persists after basic troubleshooting, contact a qualified HVAC technician for diagnosis and repair.
