Common Issues
Having trouble with your Bryant Plus 90 furnace? You’re not alone. Many homeowners face common issues with their furnaces, especially during the colder months. Knowing these issues can help you troubleshoot and potentially fix them. Let’s dive into some of the most frequent problems you might encounter.
No Heat
Is your furnace running, but there’s no heat? Here are some possible causes:
- Thermostat settings: Ensure the thermostat is set to “heat” and the temperature is above room temperature.
- Power supply: Check the circuit breaker and ensure the furnace is receiving power.
- Pilot light: If your furnace has a pilot light, ensure it is lit. If not, follow the manufacturer’s instructions to relight it.
- Air filter: A clogged air filter can restrict airflow. Replace it if necessary.
Insufficient Heat
If your furnace is producing some heat, but not enough, consider these factors:
- Dirty burners: Dirt and debris on the burners can affect performance. Clean them carefully.
- Blocked vents: Ensure that all vents and registers are open and unobstructed.
- Blower motor: A faulty blower motor may not be pushing enough air through the system. Check for any signs of wear or damage.
- Thermostat calibration: The thermostat may need to be recalibrated for accurate temperature readings.
Frequent Cycling
A furnace that frequently turns on and off can be frustrating. Here are some reasons for frequent cycling:
- Thermostat location: If the thermostat is near a heat source, it may cause short cycling. Relocate it if necessary.
- Overheating: The furnace may be overheating due to a dirty filter or blocked vents. Clean or replace the filter and ensure proper airflow.
- Limit switch: A faulty limit switch can cause the furnace to cycle frequently. This may require professional replacement.
By understanding these common issues, you can keep your Bryant Plus 90 furnace running efficiently. Regular maintenance is key. When in doubt, always consult a professional HVAC technician.

Basic Checks
Experiencing issues with your Bryant Plus 90 Furnace? Start with basic checks. Simple steps can often resolve common problems. Here are three essential checks to perform.
Thermostat Settings
Ensure your thermostat is set to “Heat”. Check the temperature setting. It should be higher than the current room temperature. Also, verify the thermostat batteries are not dead.
Power Supply
Ensure the furnace is receiving power. Check the circuit breaker. It should be in the “On” position. Confirm the power switch near the furnace is also on. A tripped breaker or off switch can stop the furnace from working.
Air Filter
A clogged air filter can cause furnace issues. Inspect the air filter. If it looks dirty, replace it. A clean filter ensures proper airflow. This can improve furnace performance.
Error Codes
The Bryant Plus 90 Furnace is a reliable heating system.
Yet, like all machines, it can face issues.
Understanding the error codes is crucial for troubleshooting.
These codes help diagnose and fix problems quickly.
Interpreting Codes
Error codes appear on the furnace’s control panel.
Each code signals a specific issue.
Learning to read these codes is essential.
The codes are usually a mix of numbers and letters.
Refer to the user manual for detailed explanations.
Below is a quick guide to common error codes.
Common Error Codes
| Error Code | Description |
|---|---|
| 31 | Pressure switch fault |
| 32 | Low pressure switch fault |
| 33 | Limit switch fault |
| 34 | Ignition proving failure |
| 41 | Blower motor fault |
The table above lists some of the most common error codes.
Each code points to a specific issue with the furnace.
Address these issues promptly to maintain your furnace’s performance.
Steps To Take
Follow these steps if you see an error code:
- Turn off the furnace.
- Check the user manual for the error code meaning.
- Inspect the relevant part of the furnace.
- Fix the issue or call a technician.
By understanding and addressing error codes, you ensure your furnace runs smoothly.
Ignition Problems
Dealing with ignition problems in your Bryant Plus 90 furnace can be frustrating. Ignition issues mean your furnace won’t start. This can leave you without heat during cold weather. Let’s explore some common ignition problems.
Pilot Light
The pilot light is crucial for starting your furnace. If the pilot light goes out, the furnace won’t heat. Check if the pilot light is on. If it’s off, try relighting it. Follow the manufacturer’s instructions. If it still won’t stay lit, there might be a draft or a blockage. Cleaning the pilot light opening can help.
Ignitor Issues
Modern furnaces use electronic ignitors. These ignitors replace old pilot lights. If the ignitor is faulty, the furnace won’t start. Look for visible cracks or damage. A faulty ignitor often needs replacement. Make sure to turn off the power before inspecting it. Always refer to your furnace manual for guidance.
Blower Motor
The blower motor in your Bryant Plus 90 furnace is crucial. It pushes warm air throughout your home. Sometimes, issues with the blower motor can disrupt your heating. Understanding common problems can help you fix them quickly.
No Airflow
If there’s no airflow, the blower motor might be the issue. First, check the thermostat settings. Ensure it’s set to “heat” and the fan is on “auto” or “on.” Next, check the circuit breaker. It might have tripped, cutting power to the furnace. Reset it if needed. Also, inspect the blower motor itself. Look for visible damage or loose wiring. Sometimes, the motor might need a simple reset. Follow the manufacturer’s instructions for this.
Weak Airflow
Weak airflow can also point to blower motor problems. Start by checking the air filter. A dirty filter can restrict airflow. Replace it if it’s clogged. Next, inspect the blower motor for dust and debris. Clean it carefully to ensure smooth operation. Another cause might be the blower motor capacitor. This part helps the motor start and run. If it’s faulty, the motor may struggle. Replacing the capacitor can often resolve weak airflow issues.
Heat Exchanger
The heat exchanger is a crucial part of the Bryant Plus 90 furnace. It transfers heat from the furnace to the air that circulates through your home. This component must work properly for your furnace to function efficiently. Let’s explore common issues like cracks and blockages that can affect the heat exchanger.
Cracks
Cracks in the heat exchanger can lead to serious problems. These cracks may allow carbon monoxide to leak into your home. Here’s how to check for cracks:
- Turn off the furnace and let it cool.
- Remove the access panel to the heat exchanger.
- Inspect the exchanger with a flashlight for any visible cracks.
- If you see any, contact a professional immediately.
It’s important to perform these checks regularly. Cracks can develop over time and go unnoticed.
Blockages
Blockages in the heat exchanger can reduce airflow. This makes the furnace work harder and can lead to overheating. Here’s how to identify and fix blockages:
- Turn off the furnace before inspecting.
- Check the exchanger for any debris or dust buildup.
- If you see any blockages, use a soft brush to clean the area.
- Ensure no objects are blocking the air intake vents.
Regular maintenance can help prevent these blockages. Keeping the heat exchanger clean ensures efficient operation.
| Issue | Signs | Solution |
|---|---|---|
| Cracks | Visible cracks, strange noises | Contact a professional |
| Blockages | Reduced airflow, overheating | Clean the exchanger |
Understanding these common issues can help you maintain your furnace. A well-maintained heat exchanger will keep your home warm and safe.
Gas Supply
Ensuring a steady gas supply is vital for your Bryant Plus 90 furnace. Issues with the gas supply can lead to furnace malfunctions. Let’s explore some common problems related to the gas supply.
Valve Issues
The gas valve controls the flow of gas to the furnace. If the valve is faulty, the furnace may not receive enough gas.
- Stuck Valve: A valve stuck in the closed position will block gas flow.
- Leaking Valve: A leaky valve can cause gas to escape, reducing efficiency.
Check if the valve is open and not damaged. If you suspect a problem, contact a technician.
Pressure Problems
Proper gas pressure ensures the furnace operates efficiently. Low or high pressure can cause issues.
| Pressure Issue | Effect on Furnace |
|---|---|
| Low Pressure | The furnace may not ignite or run poorly. |
| High Pressure | Can damage the furnace and cause safety issues. |
If you suspect a pressure issue, use a manometer to check the gas pressure. Adjustments should be made by a professional.
