Common Issues With Conquest 90 Furnace

The Conquest 90 furnace can face several common issues leading to decreased performance or complete failure. Understanding these problems can help you troubleshoot effectively.

Ignition Problems

Ignition issues frequently cause the Conquest 90 furnace to fail. If the furnace doesn’t ignite, check these areas:

1. Pilot Light: If the pilot light is out, relight it according to the manufacturer’s instructions. Be sure to let gas settle beforehand.
2. Ignitor: Inspect the ignitor for damage or wear. A faulty ignitor can prevent proper lighting.
3. Gas Supply: Ensure that the gas valve is open. Verify that there’s gas flowing to the unit.

1. Settings: Confirm that the thermostat is set to “heat” and programmed to a temperature higher than room temperature.
2. Power Supply: Check the power supply to the thermostat. Replace batteries if applicable.
3. Wiring Issues: Inspect the wiring for disconnections or damage. Loose wires can interrupt communication between the thermostat and the furnace.

Troubleshooting Steps

To get your Conquest 90 furnace working again, follow these troubleshooting steps. Start with the basics before moving to more technical aspects.

Checking the Power Supply

1. Inspect the Circuit Breaker: Check the circuit breaker panel for tripped breakers. Reset any that are off to restore power.
2. Examine the Power Cord: Look for damage or loose connections in the power cord. Ensure it’s firmly plugged into an outlet.
3. Test Outlets: Use a multimeter to test the outlet for voltage. If there’s no power, you may need to call an electrician.

1. Locate the Thermocouple: Find the thermocouple near the pilot light. It’s a small metal sensor that detects the flame.
2. Clean the Thermocouple: Use fine-grit sandpaper to gently clean the thermocouple’s tip. Dirt or soot can prevent it from sensing the flame properly.
3. Check Alignment: Ensure the thermocouple is aligned with the pilot light. It should be positioned to catch the flame’s heat directly.

By following these steps, you can identify potential issues that may be preventing your Conquest 90 furnace from functioning properly.

Repair Options

When your Conquest 90 furnace isn’t working, explore two primary repair options: DIY fixes and professional assistance. Addressing the issue promptly can help restore comfort in your home.

DIY Fixes

Start troubleshooting by following these steps:

1. Check the Thermostat: Ensure the thermostat is set to “heat” and the temperature is higher than your current room temperature. Adjust as necessary.
2. Inspect the Pilot Light: If the pilot light is out, follow the manufacturer’s instructions to relight it. Make sure to turn off the gas supply before attempting to relight.
3. Examine the Ignitor: Test the ignitor by looking for any visible damage or wear. If it appears faulty, replacing it is a straightforward process.
4. Clean the Thermocouple: Gently clean the thermocouple with a cloth to remove any debris or soot, which can impede its function.
5. Reset the Furnace: Locate the reset button on the furnace and push it. This can often resolve minor issues.
6. Check the Circuit Breaker: Inspect the circuit breaker box for any tripped breakers related to the furnace. Reset any that are off.
7. Look for Gas Supply Issues: Confirm that the gas valve is open and the line is unobstructed. If you suspect a gas leak, contact emergency services immediately.

These steps can help identify and possibly fix common issues without professional help.

Professional Assistance

If DIY fixes don’t resolve the problem, contact a qualified technician. This professional should:

1. Perform a Comprehensive Inspection: Technicians can assess the entire heating system, identifying underlying issues that may not be visible to you.
2. Diagnose Electrical Problems: They can determine whether there are electrical issues impacting your furnace’s operation.
3. Handle Complex Repairs: Technicians manage repairs that involve gas lines or intricate components safely, reducing the risk of accidents.
4. Service the Furnace Regularly: Regular maintenance from professionals can prevent future breakdowns, prolonging the life of your system.
5. Provide Warranty Information: inquire about warranties or service plans, which can save money on future repairs.

Choosing the right assistance ensures your Conquest 90 furnace operates efficiently and safely.

Preventative Maintenance Tips

Regular maintenance helps you avoid issues with your Conquest 90 furnace. Following specific tips keeps it running smoothly and efficiently.

Regular Inspections

Conduct regular inspections to catch potential problems early. Inspect the furnace at least twice a year, ideally before the heating season starts. Look for any signs of wear, such as rust or corrosion. Verify that all components function correctly, including the thermostat, ignitor, and gas supply. Check the air filters and replace them if they appear dirty. Clean filters improve airflow and enhance efficiency.

Cleaning the Furnace

Cleaning your furnace contributes to optimal performance. Remove dust and debris from the exterior surfaces using a soft cloth. Ensure the area around the furnace remains clutter-free to promote proper airflow. Inspect the burner assembly and clean any soot or buildup. If necessary, consult your owner’s manual for specific cleaning instructions. Keeping the furnace clean reduces the risk of malfunctions and extends its lifespan.

Conclusion

Getting your Conquest 90 furnace back in working order doesn’t have to be overwhelming. By taking a few simple steps to troubleshoot, you can often identify the problem yourself. Remember to check the power supply, inspect the pilot light, and ensure everything’s clean and aligned.

If you find that DIY fixes aren’t cutting it, don’t hesitate to reach out to a professional. They can help get your furnace running smoothly again while ensuring it operates safely.

And don’t forget about preventative maintenance. Regular check-ups can save you time and money in the long run, keeping your home cozy when you need it most. Stay warm and comfortable this winter!
