Understanding Electric Furnace Emergency Heat
Emergency heat is a vital feature of electric furnaces designed to maintain warmth during system failures or extreme cold.
What Is Emergency Heat?
Emergency heat refers to an alternative heating setting available in electric furnaces, typically used when the primary heating system fails. This function activates backup heaters, which rely solely on electric resistance heating. Homeowners use emergency heat primarily during sudden breakdowns or when outdoor temperatures drop significantly.
How Does Emergency Heat Function?
Emergency heat operates by bypassing the standard heating cycle. When activated, it sends electricity directly to resistance coils in the furnace. These coils generate heat, providing immediate warmth. You control this setting through the thermostat, which features a dedicated emergency heat switch.
Using this function can lead to increased electricity usage. Emergency heat might not be as efficient as the regular heating system but guarantees comfort when the primary heater isn’t working.
Common Reasons for Emergency Heat Failure
Emergency heat failure can happen for several reasons. Understanding these can help you troubleshoot the issue effectively.
Thermostat Issues
Thermostat problems often cause emergency heat not to activate. Check for the following issues:
- Incorrect Settings: Ensure your thermostat is set to “Emergency Heat” or “Auxiliary Heat.” Sometimes it’s set to “Off” or “Cool” by mistake.
- Dead Batteries: If your thermostat runs on batteries, replace them to ensure proper functioning.
- Faulty Wiring: Inspect wiring connections, as loose or damaged wires can prevent signals from reaching the furnace.
- Calibration Issues: A poorly calibrated thermostat may give inaccurate temperature readings, causing the system to remain off.
Electrical Problems
Electrical issues can disrupt the furnace’s ability to operate in emergency mode. Consider these problems:
- Blown Fuses: Locate and check the fuse box; blown fuses may cut off power to the furnace.
- Tripped Circuit Breakers: If the circuit breaker trips, reset it and see if the furnace activates.
- Voltage Issues: Verify that the furnace receives the correct voltage. Low voltage could lead to malfunction.
- Burned Out Relays: Inspect the relays in the electrical components, as burned-out relays can prevent the system from starting.
Furnace Component Failures
Failures in specific furnace components can also lead to emergency heat not working. Pay attention to these critical parts:
- Heating Elements: Examine the heating elements for any visible damage or burnt spots; faulty elements can’t generate heat.
- Blower Motor Issues: A malfunctioning blower motor may prevent warm air from circulating, even if the heating elements function properly.
- Limit Switch Problems: If the limit switch is stuck or malfunctioning, it can stop the system from running to prevent overheating.
- Control Board Failures: Inspect the control board for any signs of damage or burning, as this component manages system operations.
By understanding these common reasons for emergency heat failure, you can troubleshoot effectively and restore warmth to your home.
Troubleshooting Steps for Homeowners
Follow these troubleshooting steps to resolve the issue of your electric furnace emergency heat not working.
Checking the Thermostat Settings
Check the thermostat settings first. Set the thermostat to “Emergency Heat” to bypass normal operations. Ensure the temperature setting is above the current room temperature. If it’s still unresponsive, replace the batteries if applicable. Dead batteries can prevent the thermostat from sending signals to the furnace.
Inspecting the Circuit Breaker
Next, inspect the circuit breaker. Locate your electrical panel and ensure the breaker for the furnace is in the “On” position. If it’s tripped, reset it by flipping it fully to the “Off” position, then back to “On.” Look for blown fuses as well, particularly in older homes. Replacing a blown fuse or resetting the breaker often serves as a quick fix for power-related issues.
Examining the Air Filter
Examine the air filter as well. A clogged air filter can restrict airflow, causing overheating or system shutdowns. Replace the filter if it’s dirty or has not been changed in over three months. Regularly maintaining your filter ensures the furnace operates efficiently, which can prevent further issues during cold months.
When to Call a Professional
Calling a professional becomes essential when troubleshooting doesn’t resolve your electric furnace emergency heat issues. Recognizing the signs can prevent further damage and ensure safety and comfort.
Signs That Require Expert Help
- Unusual Noises: You notice grinding, banging, or squealing sounds. These sounds often signal mechanical issues.
- Persistent Lack of Heat: Emergency heat remains non-functional despite following troubleshooting steps.
- Burning Smell: You detect a burning odor, indicating potential electrical problems or overheating.
- Frequent Tripping of Circuit Breaker: The circuit breaker trips repeatedly, indicating an overload or electrical malfunction in the system.
- Increased Energy Bills: A sudden spike in energy costs may result from inefficiencies or hidden system problems.
- Check Credentials: Confirm the technician has proper licenses and certifications. Authorized professionals guarantee skill and knowledge.
- Read Reviews: Look for customer reviews and testimonials online. Positive feedback reflects a technician’s reliability and service quality.
- Ask for Referrals: Request recommendations from friends or family. Referrals often lead to trustworthy service providers.
- Get Multiple Quotes: Obtain estimates from different technicians. Comparing prices can help you find the best deal while ensuring quality service.
- Inquire About Experience: Confirm the technician’s experience with electric furnaces. Specialized knowledge ensures efficient and effective repairs.
Conclusion
Dealing with an electric furnace emergency heat that won’t work can be frustrating especially during those chilly nights. By understanding the common issues and following the troubleshooting steps outlined in this post you can take control of the situation.
Don’t hesitate to check your thermostat settings and inspect your circuit breaker. Regular maintenance on your air filter can also make a big difference. If you find yourself overwhelmed or notice any unusual signs it’s best to call in a professional.
Your comfort is important and with a little effort you’ll be able to keep your home warm and cozy all winter long.
