Common Issues And Symptoms
Homeowners may encounter several common issues with their Armstrong Ultra 90 furnace. Recognizing these symptoms can lead to effective troubleshooting and repairs.
Ignition Problems
Ignition problems often manifest as a failure to start or repeated cycling. If your furnace doesn’t ignite, check the following:
- Pilot Light: Ensure the pilot light is lit. If not, try relighting it according to the manufacturer’s instructions.
- Ignitor: Inspect the ignitor for damage or wear. A faulty ignitor may need replacement.
- Gas Supply: Confirm the gas supply is on. A closed valve can prevent ignition.
Thermostat Malfunctions
Thermostat issues may cause your furnace to operate erratically. Look for these symptoms:
- Incorrect Settings: Verify the thermostat settings. It should be set to “heat” and at a temperature higher than the current room temperature.
- Dead Batteries: Check and replace batteries if you have a battery-operated thermostat.
- Wiring Issues: Inspect wiring for loose connections or frayed wires. Faulty wiring may require professional assistance.
Insufficient Heat
If your home isn’t heating sufficiently, diagnose potentially related issues:
- Dirty Filters: Clogged air filters restrict airflow. Change the filter every 1-3 months for optimal performance.
- Duct Leaks: Inspect ductwork for leaks. Sealing gaps improves heat distribution.
- Blocked Vents: Ensure vents are unobstructed to allow maximum heat flow throughout the space.
Identifying these issues provides a solid foundation for troubleshooting your Armstrong Ultra 90 furnace.
Troubleshooting Steps
Follow these troubleshooting steps to identify and resolve common issues with your Armstrong Ultra 90 furnace.
Checking Power Supply
Ensure the furnace has power. Check the following:
- Circuit Breaker: Look for tripped breakers in your home’s panel. Reset any that are off.
- Power Switch: Confirm the power switch on the furnace is in the “On” position.
- Electrical Connections: Inspect wires and plugs for secure connections. Loose wires may disrupt power.
Inspecting Thermostat Settings
Verify the thermostat settings for any discrepancies:
- Temperature Setting: Set the thermostat above room temperature to trigger the furnace.
- Mode Setting: Ensure the thermostat is in “Heat” mode and not “Cool” or “Off.”
- Battery Status: If applicable, replace the thermostat batteries to maintain functionality.
Examining the Flame Sensor
A dirty or faulty flame sensor can disrupt operation. Perform these checks:
- Clean the Flame Sensor: Turn off power and remove the flame sensor. Use fine sandpaper or steel wool to clean it gently. Reinstall once cleaned.
- Check for Proper Connection: Ensure the flame sensor’s wiring is connected securely.
Cleaning or Replacing Filters
Dirty filters can block airflow and reduce efficiency. Follow these steps:
- Inspect Filters Monthly: Remove the air filter and check for dust buildup. A clean filter promotes efficient airflow.
- Replace Filters as Needed: If the filter is dirty, replace it with the correct size. Aim for replacement every 1-3 months during peak usage.
- Regular Maintenance: Establish a routine to ensure filters remain clean, especially during winter months.
Address these steps methodically to troubleshoot the Armstrong Ultra 90 furnace effectively.
Maintenance Tips
