5. Operating Instructions

The Goodman HKR-10 Electric Heat Kit operates automatically as part of your HVAC system, controlled by your thermostat. When the thermostat calls for heat and the primary heating source (e.g., heat pump) cannot meet the demand, or during defrost cycles, the electric heat kit will activate to provide supplemental heating.

• Ensure your thermostat is set to the desired heating temperature.
• The heat kit will engage as needed to maintain the set temperature.
• Refer to your air handler or packaged unit's manual for specific operational details and thermostat settings.

6. Maintenance

Regular maintenance of your entire HVAC system, including the electric heat kit, is crucial for optimal performance and longevity. Always ensure power is disconnected before performing any maintenance.

• Annual Inspection: Have a qualified technician inspect the electric heat kit annually. This includes checking electrical connections, heating elements, and safety controls.
• Air Filter Replacement: Ensure the air filter in your air handler is replaced regularly according to the manufacturer's recommendations. A clean filter ensures proper airflow over the heating elements, preventing overheating and maintaining efficiency.
• Clear Airflow: Ensure that the air handler and all vents are free from obstructions to allow for proper air circulation.

7. Troubleshooting

If your electric heat kit is not functioning as expected, consider the following basic troubleshooting steps. For complex issues, contact a qualified HVAC technician.

• No Heat:
  • Check the thermostat setting to ensure it is calling for heat.
  • Verify that the circuit breaker for the HVAC system and the electric heat kit is not tripped.
  • Ensure the air handler unit has power.
• Insufficient Heat:
  • Check the air filter for cleanliness; a dirty filter can restrict airflow.
  • Ensure all supply and return air vents are open and unobstructed.
• Unusual Odors:
  • A slight burning odor may occur during the first few uses as dust burns off the heating elements. If the odor persists or is strong, disconnect power and contact a technician.
