Common Issues with Armstrong Gas Furnaces
Armstrong gas furnaces can experience a range of problems, particularly in the colder months. Understanding these common issues helps you troubleshoot effectively.
No Heat
If your Armstrong gas furnace isn’t producing heat, check the thermostat first. Ensure it’s set to “heat” and the temperature is higher than the current room temperature.
Next, inspect the furnace’s power supply. Make sure the circuit breaker hasn’t tripped or the fuse hasn’t blown. If the furnace still won’t operate, look at the gas valve. It should be in the “on” position.
Consider checking the pilot light. If it’s out, follow the manufacturer’s instructions for relighting it. If you’re dealing with an electronic ignition system, listen for a clicking noise. If there’s no sound, the ignition component may need replacement.
Weak Airflow
Weak airflow can lead to uneven heating in your home. First, examine the air filters. Clogged filters hinder airflow. Replace or clean filters every 1-3 months for optimal performance.
Next, inspect the vents. Ensure they’re open and unobstructed by furniture or debris. Close duct dampers that direct airflow unnecessarily.
Also, consider the blower motor. If it’s malfunctioning, it may not circulate air effectively. Listen for unusual noises. If you hear grinding or rattling sounds, seek a technician’s assistance to resolve the issue.
By addressing these common issues proactively, you can maintain your Armstrong gas furnace’s efficiency and comfort during winter.
Troubleshooting Steps
Follow these troubleshooting steps to diagnose and fix common issues with your Armstrong gas furnace.
Checking Thermostat Settings
Start by checking the thermostat settings. Ensure the thermostat is set to “heat” and the desired temperature is higher than the current room temperature. Sometimes, a simple adjustment resolves the issue. If the thermostat is programmable, ensure it’s not on an energy-saving mode that restricts heating. Replace the batteries if the display is dim or non-responsive.
Inspecting the Air Filter
Inspect the air filter next. A dirty or clogged air filter restricts airflow, reducing heating efficiency. Remove the filter and hold it up to a light source. If you can’t see light passing through, it’s time to replace it. Aim to check or replace the filter every one to three months, especially during heavy usage seasons.
Examining the Flame Sensor
Examine the flame sensor for dirt or corrosion. A dirty flame sensor may prevent the furnace from igniting. Turn off the power to the furnace for safety, then remove the sensor, clean it gently with a fine sandpaper or cloth, and re-install it. If the furnace still doesn’t operate, consider replacing the flame sensor, as a faulty one won’t allow the furnace to ignite properly.
Maintenance Tips
Maintain your Armstrong gas furnace for optimal performance and efficiency. Here are some practical tips to keep it running smoothly.
Regular Cleaning
Clean various components regularly to enhance furnace function.
- Air Filters: Replace or clean filters every month during peak usage. Clogged filters block airflow and strain the system.
- Vents and Ducts: Inspect and clear vents of dust and debris. Ensure nothing obstructs airflow to rooms.
- Blower Assembly: Dust and clean the blower assembly every few months. A clean blower improves efficiency.
- Area Around Furnace: Keep the space around the furnace free from obstructions. Ensure proper air circulation around the unit.
Annual Inspections
Schedule annual inspections to catch issues early.
- Professional Check-Up: Hire an HVAC technician for a thorough inspection once a year. They’ll assess the system and identify potential problems.
- Gas Line Inspection: Ensure the gas line isn’t leaking. A technician can safely check this and make necessary repairs.
- Safety Controls: Verify that all safety controls, including the limit switch and flame sensor, are functioning correctly. Proper safety controls prevent hazardous situations.
- Exhaust System: Inspect the exhaust system for blockages. Ensure vent pipes are free from leaves, snow, or any obstruction.
By following these maintenance tips, you can ensure your Armstrong gas furnace operates efficiently and safely throughout the winter months.
When to Call a Professional
Certain situations indicate a need for professional assistance with your Armstrong gas furnace. Recognizing these signs can save time and prevent potential hazards.
Persistent Issues
If troubleshooting steps don’t resolve the problem, calling a professional becomes essential. Repeatedly encountering issues like lack of heat or strange noises could signal deeper mechanical or electrical problems.
Gas Leaks
Detecting a gas odor suggests an immediate need for professional help. Gas leaks pose serious safety risks. If you smell gas, turn off the furnace, evacuate your home, and contact a technician immediately.
Carbon Monoxide Alarms
If your carbon monoxide detector goes off, treat the situation with urgency. Evacuate the premises and call emergency services. A malfunctioning gas furnace can lead to carbon monoxide buildup, which is life-threatening.
Complex Repairs
Certain repairs require specialized knowledge. Issues with the ignition system, gas line, or internal components often exceed DIY capabilities. Technicians have the tools and expertise to handle complexities safely.
Age of the Furnace
If your furnace is over 15 years old, consider consulting a professional for an evaluation. Aging systems may need repairs or replacements that require expert guidance.
Safety Concerns
Never compromise on safety. If something about the furnace seems unusual, it’s better to err on the side of caution and call a licensed technician. They’ll ensure that everything operates smoothly and safely.
Conclusion
Taking care of your Armstrong gas furnace doesn’t have to be a daunting task. With a little troubleshooting know-how and regular maintenance you can keep your home warm and cozy all winter long. Remember to check those thermostat settings and air filters first.
If you encounter persistent issues don’t hesitate to reach out to a professional. Your safety is the top priority. By staying proactive and attentive you can enjoy a reliable heating system that keeps you comfortable season after season. Happy heating!
