2. Important Safety Information

WARNING: Risk of electric shock, gas leak, or fire.

• Installation of this part should only be performed by a qualified technician. Improper installation can lead to serious injury or property damage.
• Always disconnect electrical power to the furnace and turn off the gas supply at the main valve before attempting any installation, repair, or maintenance.
• Wear work gloves to protect your hands from sharp edges and potential hazards during installation.
• After installation, carefully check all gas connections for leaks using a non-corrosive leak detection solution. Never use an open flame to check for gas leaks.
• Ensure all wiring connections are secure and correctly routed according to the furnace manufacturer's specifications.

4. Installation Instructions

Follow these general steps for replacing a furnace gas valve. Always consult your furnace's specific service manual for detailed instructions relevant to your model.

1. Preparation: Ensure all safety precautions from Section 2 are followed. Turn off electrical power to the furnace and shut off the gas supply.
2. Access: Locate the existing gas valve within your furnace. You may need to remove access panels.
3. Disconnect Wiring: Carefully label and disconnect all electrical wires connected to the old gas valve. Take photos if necessary for reassembly.
4. Disconnect Gas Lines: Using appropriate wrenches, disconnect the gas supply lines from the old valve. Be prepared for a small amount of residual gas.
5. Remove Old Valve: Unmount and remove the old gas valve from the furnace.
6. Install New Valve: Position the new Kenmore 36C03-333 gas valve in place. Secure it using the original mounting hardware.
7. Connect Gas Lines: Reconnect the gas supply lines to the new valve. Use new pipe thread sealant (rated for gas) on all threaded connections. Tighten connections securely but do not overtighten.
8. Connect Wiring: Reconnect all electrical wires to the new gas valve, matching them to the labels or photos taken earlier.
9. Leak Test: Turn on the main gas supply. Apply a non-corrosive leak detection solution (e.g., soapy water) to all gas connections. Look for bubbles, which indicate a leak. If leaks are found, tighten connections or reapply sealant until no bubbles appear.
10. Restore Power: Once all connections are secure and leak-free, restore electrical power to the furnace.
11. Test Operation: Follow your furnace's startup procedure to test the new gas valve's operation. Observe for proper ignition and flame characteristics.

5. Operation

The Kenmore 36C03-333 gas valve operates automatically as part of your furnace's control system. When the thermostat calls for heat, the furnace's control board sends a signal to the gas valve to open, allowing gas to flow to the burner. Simultaneously, the igniter (hot surface igniter or pilot light) will ignite the gas, producing heat.

The gas valve will remain open until the thermostat's heat demand is met or a safety limit is tripped, at which point it will close to shut off the gas supply.

6. Maintenance

The gas valve itself is generally a sealed component and does not require routine user maintenance. However, regular maintenance of your overall furnace system is crucial for the longevity and safe operation of all components, including the gas valve.

• Annual Professional Inspection: It is highly recommended to have your furnace inspected and serviced annually by a qualified HVAC technician. They can check the gas valve for proper operation, gas pressure, and signs of wear or leaks.
• Keep Area Clear: Ensure the area around your furnace is kept clear of obstructions, flammable materials, and debris to allow for proper airflow and safe operation.
• Filter Replacement: Regularly replace or clean your furnace air filter as recommended by your furnace manufacturer. A clean filter helps maintain efficient operation and reduces strain on components.

7. Troubleshooting

If your furnace is not operating correctly after installing the gas valve, or if you suspect an issue with the gas valve, consider the following:

• No Heat:
  • Check if the gas supply to the furnace is turned on.
  • Verify that the thermostat is set to "Heat" and the temperature is above the current room temperature.
  • Ensure the furnace's power switch is on.
  • Listen for the igniter and the sound of gas flowing when the furnace attempts to start. If no gas flow is heard, the gas valve may not be opening.
• Gas Smell:
  • If you smell gas, immediately turn off the gas supply to the furnace and evacuate the premises. Do not operate any electrical switches or phones. Contact your gas utility company and a qualified HVAC technician from a safe location.
• Pilot Light Issues (if applicable):
  • If your furnace has a pilot light, ensure it is lit. Refer to your furnace manual for pilot relighting instructions. A faulty gas valve can prevent gas from reaching the pilot.

IMPORTANT: For any issues involving gas or complex furnace malfunctions, always contact a certified HVAC professional. Do not attempt repairs beyond your skill level, especially with gas components.
