Is your heat pump struggling to keep your home warm? You’re not alone. Many homeowners face issues with their auxiliary heat systems, especially during those chilly winter months. When the temperature drops, you expect your heat pump to kick in and keep you cozy, but what happens when it doesn’t?
In this article, you’ll discover the common reasons your auxiliary heat might not be working and how to troubleshoot the problem. By understanding these issues, you can take steps to restore warmth to your home and avoid costly repairs. Let’s get started so you can get back to enjoying a comfortable living space.
Key Takeaways
- Understand Auxiliary Heat Functionality: Auxiliary heat systems are essential for maintaining home warmth when temperatures drop below 30°F, making familiarity with their operation crucial for troubleshooting.
- Common Malfunctions: Issues like incorrect thermostat settings, tripped breakers, and faulty components can hinder your auxiliary heat pump’s performance.
- DIY Troubleshooting Tips: Regularly inspect your thermostat, circuit breaker, air filters, and ductwork to identify and address issues before they escalate.
- When to Seek Professional Help: Persistent problems such as no warm air, frequent cycling, error codes, strange noises, or frozen coils warrant immediate professional inspection to prevent further damage.
- Regular Maintenance is Key: Schedule annual maintenance check-ups for your system to spot potential issues early and ensure your heat pump operates efficiently during colder months.
Overview of Auxiliary Heat Heat Pumps
Auxiliary heat heat pumps supplement your primary heating system. They activate when outside temperatures drop too low for the heat pump to efficiently extract heat from the air. Understanding how these systems work helps you troubleshoot issues when they arise.
How Auxiliary Heat Functions
Auxiliary heat systems use alternate heat sources, such as electric resistance coils, to maintain indoor comfort during extreme cold. These systems activate automatically when the heat pump can’t provide sufficient warmth, typically below 30°F (-1°C). This process ensures consistent heating in your home.
Common Reasons for Malfunction
- Thermostat Settings: Check that the thermostat has the correct settings for auxiliary heat. Incorrect adjustments can prevent activation.
- Tripped Breaker: Sometimes, the circuit breaker for the auxiliary heat may trip. Reset it to restore power.
- Faulty Components: Issues with relays or contactors may impede the system. Regular maintenance helps identify wear and tear.
- Insufficient Insulation: Poor insulation around windows or doors can cause excessive heat loss. This situation forces auxiliary heat to work harder, possibly leading to failure.

- Inspect Thermostat: Ensure it’s set to “Heat” and check for any error messages. Replace batteries if needed.
- Check Circuit Breaker: If trips occur often, consult a professional electrician for further inspection.
- Evaluate Air Filters: Clean or replace filters regularly. Clogged filters can hinder airflow and efficiency.
- Examine Ductwork: Look for visible leaks or obstructions in the ductwork. Seal any gaps to improve performance.
- Schedule Professional Maintenance: Annual check-ups can spot potential issues early, ensuring the system runs efficiently.
By knowing how auxiliary heat heat pumps function and troubleshooting effectively, you can maintain comfort in your home, even during the coldest months.
Common Issues Leading to Auxiliary Heat Heat Pump Not Working
Auxiliary heat heat pumps can encounter several problems, preventing them from providing the warmth you need. Here are some common issues to consider.
Thermostat Settings
Incorrect thermostat settings often cause your auxiliary heat system to malfunction. Check that your thermostat is set to the appropriate mode, such as “Heat” or “Auxiliary Heat.” Ensure the temperature setting is higher than the current room temperature; if it’s not, the system won’t activate. Additionally, a miscalibrated thermostat can lead to incorrect readings. Testing it with a separate thermometer can help verify its accuracy.
Electrical Failures
Electrical failures play a significant role in auxiliary heat system issues. Tripped circuit breakers or blown fuses can disrupt power supply, preventing the system from working. Inspect the circuit breaker panel for any tripped breakers and reset them if necessary. Also, check for damaged wiring or loose connections. Faulty electrical components, like the contactor or capacitor, can impede operation. If the system still doesn’t work after addressing these faults, seeking professional assistance may be necessary.
Troubleshooting Steps for Auxiliary Heat Heat Pump Not Working
If your auxiliary heat heat pump isn’t working, a few simple steps may help you identify and resolve the issue quickly.
Check the Thermostat
Ensure the thermostat is set to the appropriate mode. For auxiliary heat, select “heat” mode instead of “cool.” Verify the temperature setting. If it’s too low, the heat pump won’t activate. Check for a programmable thermostat, as schedules may interfere with operation. Replace the batteries if applicable and ensure it’s securely mounted. If the thermostat still shows issues, consider recalibrating it or replacing it if necessary.

Inspect the Circuit Breaker
Examine the circuit breaker for any tripped switches. If the power to the heat pump has been interrupted, reset the breaker by switching it off and back on. Check for blown fuses. If the circuit breaker trips again, it indicates a more significant problem, such as faulty wiring or an overloaded circuit. In that case, consult a professional for a thorough inspection to prevent further damage.
When to Call a Professional
You might need to call a professional if you encounter persistent issues with your auxiliary heat pump. Look out for these signs:
- No Warm Air
If you turn on your system but don’t feel warm air coming through the vents, a malfunctioning unit could be the cause. - Frequent Cycling
If the heat pump runs for short periods and then stops frequently, you might be dealing with an underlying problem that needs expert attention. - Error Codes
If your thermostat displays an error code and you’re unsure how to fix it, it’s time to consult a professional. - Strange Noises
If you hear unusual sounds like grinding, banging, or hissing, these noises might indicate mechanical failure or another serious issue. - Increased Energy Bills
If you notice a sudden spike in your energy bills without a corresponding increase in usage, your heat pump might be working harder than it should due to malfunctions. - Frozen Coils
If ice forms on the outdoor unit or any refrigerant lines, immediate professional evaluation is necessary to prevent further damage. - Lasting Odors
If you detect strange smells coming from the system, such as burning or chemical odors, turn off the heat pump and contact a professional immediately.
In any of these situations, getting a trained technician involved can help diagnose the issue accurately and restore your system to optimal working conditions. Remember, timely professional assistance can prevent costlier repairs down the line.
Conclusion
Dealing with an auxiliary heat pump that isn’t working can be frustrating but you’re not alone in this. By understanding the common issues and following the troubleshooting steps, you can often pinpoint the problem and restore warmth to your home.
