Common Issues with Conquest 90 Furnace
Homeowners with a Conquest 90 furnace often encounter some common issues, especially during the winter months. Troubleshooting these problems can help you maintain a comfortable home and avoid unnecessary repairs.
Ignition Problems
Ignition problems frequently arise in the Conquest 90 furnace. If the furnace doesn’t ignite, check the following:
- Power Supply: Ensure the furnace receives power. Look for tripped circuit breakers or blown fuses.
- Flame Sensor: Clean the flame sensor if it’s dirty. A simple wipe can restore its functionality and improve performance.
- Ignitor Condition: Inspect the ignitor for wear or damage. Replace a faulty ignitor to restore proper ignition.
- Gas Supply: Verify that the gas valve is open. If it’s closed, the furnace won’t receive gas to ignite.
- Settings Check: Ensure the thermostat settings are accurate. Confirm that it’s set to “Heat” and adjust the temperature to a few degrees above the current room temperature.
- Battery Replacement: If your thermostat requires batteries, replace them. Low batteries can lead to erratic performance.
- Wiring Inspection: Examine the wiring connections for looseness or damage. Tighten any loose wires and replace damaged ones.
- Calibration: If the thermostat readings seem off, calibrate the thermostat according to the manufacturer’s instructions. Proper calibration ensures accurate temperature management.
Troubleshooting Steps
Follow these troubleshooting steps to identify and resolve issues with your Conquest 90 furnace. Quick checks can prevent larger problems and ensure your heating system operates efficiently.
Checking Power Supply
- Ensure the Furnace Is Plugged In: Confirm the furnace is connected to an electrical outlet.
- Inspect Circuit Breakers: Check if the circuit breaker is tripped. Reset if necessary.
- Look for Fuses: Verify that there are no blown fuses in the electrical panel. Replace fuses as needed.
- Test for Voltage: Use a multimeter to check for proper voltage at the outlet. It should typically be around 120 volts.
Inspecting the Thermostat
- Verify Settings: Confirm the thermostat is set to “Heat” and the desired temperature is above the current room temperature.
- Replace Batteries: If your thermostat uses batteries, replace them to ensure accurate readings and operation.
- Check Wiring Connections: Inspect the thermostat wiring for any loose or disconnected wires. Tighten connections as needed.
- Calibrate the Thermostat: Adjust the thermostat calibration if it consistently shows incorrect temperatures or is unresponsive.
- Locate the Flame Sensor: Find the flame sensor near the burner assembly, typically a thin, metallic rod.
- Clean the Sensor: Gently clean the flame sensor with fine-grit sandpaper or steel wool to remove soot and buildup.
- Inspect Sensor Position: Ensure the sensor is properly aligned with the flame. Adjust its position if it’s out of place.
- Test Functionality: After cleaning, restart the furnace. If the furnace still fails to ignite, consider replacing the flame sensor.
Maintenance Tips for Optimal Performance
Regular maintenance ensures your Conquest 90 furnace operates efficiently. Perform simple tasks to improve its performance and prolong its lifespan.
Regular Cleaning
Clean the furnace and its components regularly. Dust and debris can obstruct airflow and affect performance.
- Clean or Replace Filters: Check filters monthly. Dirty filters inhibit efficiency. Replace them every 1 to 3 months for optimal airflow.
- Dust the Exterior: Wipe down the outer casing and controls. A clean furnace is easier to inspect and less likely to accumulate unwanted heat.
- Inspect Ventilation: Ensure the vents are free of obstructions. Blocked vents lead to poor heating and strain the system.
Scheduled Inspections
Schedule inspections to catch potential issues early. Regular check-ups help maintain peak performance.
- Professional Check-Up: Hire a technician annually to inspect vital components. A technician ensures everything is in working order and identifies any issues before they escalate.
- Inspect Safety Features: Confirm that safety components, such as the limit switch and carbon monoxide detectors, are functioning. These ensure safe operation and protect your home.
- Review Thermostat Calibration: Check thermostat accuracy yearly. A properly calibrated thermostat optimizes heating and saves energy.
Implementing these maintenance tips keeps your Conquest 90 furnace running smoothly, ensuring a warm home throughout the cold months.
