5. Operating Instructions

After successful installation of the KIT15816 control board and ignitor, follow these steps to restore furnace operation:

1. Restore Gas Supply: Open the manual gas shut-off valve to the furnace.
2. Restore Electrical Power: Turn on the electrical power to the furnace at the main service panel.
3. Set Thermostat: Set your thermostat to a heat setting above the current room temperature to initiate a call for heat.
4. Monitor Ignition Sequence: Observe the furnace's ignition sequence. The ignitor should glow, followed by the main burner ignition.
5. Verify Operation: Ensure the furnace operates through a full heating cycle, including blower activation and proper temperature rise.
6. Replace Access Panels: Once proper operation is confirmed, replace all furnace access panels.

6. Maintenance

The KIT15816 control board is designed for reliable operation and typically requires no routine maintenance itself. However, regular maintenance of the overall furnace system is crucial for its longevity and efficiency.

• Annual Furnace Inspection: Have a qualified HVAC technician perform an annual inspection and tune-up of your furnace.
• Air Filter Replacement: Regularly check and replace your furnace's air filter as recommended by the furnace manufacturer.
• Inspect Wiring: Periodically, with power disconnected, visually inspect wiring connections to the control board for any signs of wear or looseness.
• Keep Area Clear: Ensure the area around the furnace is kept clear of obstructions and combustible materials.

7. Troubleshooting

If your furnace is not operating correctly after installing the KIT15816, consider the following common troubleshooting steps. Always ensure power and gas are disconnected before inspecting internal components.

• No Power to Furnace: Check circuit breakers and furnace disconnect switch. Ensure the furnace door panel is correctly installed, as many have safety interlocks.
• No Ignition/No Heat:
  • Verify gas supply is open.
  • Check ignitor for proper glow. If no glow, ensure it's correctly wired and not damaged.
  • Inspect flame sensor for dirt or damage (clean with fine sandpaper if dirty).
  • Ensure all wiring connections to the control board are secure.
• Blower Not Operating:
  • Check thermostat settings (fan mode).
  • Ensure blower motor wiring is secure.
  • Some control boards have diagnostic lights; consult your furnace manual for error codes.
• Intermittent Operation: This can often be due to loose connections, faulty sensors, or issues with the thermostat. Re-check all wiring.

If troubleshooting does not resolve the issue, contact a qualified HVAC technician for further diagnosis and repair.
