Resetting a Bryant furnace is a straightforward process that can resolve minor issues, such as when the furnace shuts down due to a safety mechanism or a power interruption. Follow these step-by-step instructions to reset your furnace safely and effectively.
Resetting your furnace helps resolve the following:
- Safety shutdowns triggered by overheating or power surges.
- Control board errors that need clearing.
- Issues caused by temporary gas flow interruptions.
Step-by-Step Process
1. Turn Off the Furnace
- Locate the furnace’s power switch, which usually looks like a light switch mounted near the furnace.
- Flip the switch to the Off position to completely shut down the furnace.
- If you cannot find the switch, turn off the furnace’s power by switching off the breaker labeled “Furnace” in your home’s electrical panel.
2. Wait for a Few Minutes
- Leave the furnace powered down for about 5 minutes. This allows the system to reset and clear any error codes or minor glitches.
- Use this time to inspect the furnace for obvious issues, such as dirty filters or obstructions.
3. Turn Off the Thermostat
- Go to your thermostat and set it to the Off position to prevent the furnace from starting while resetting it.
- Lower the thermostat temperature significantly as an added precaution.
4. Locate and Press the Reset Button
- Find the reset button on your Bryant furnace. This is typically located on or near the blower motor or burner box.
- Press and hold the reset button for about 30 seconds. You may feel or hear a click indicating the reset process has started.
5. Restore Power to the Furnace
- Return to the power switch or breaker panel and flip the switch back to the On position to restore power to the furnace.
6. Adjust the Thermostat
- Set your thermostat back to the desired temperature.
- Switch the thermostat to Heat mode and wait a few minutes to see if the furnace starts normally.
If the furnace doesn’t start, you can try these troubleshooting steps:
- Check the thermostat batteries.
- Make sure the thermostat is set to “heat.”
- Check that all circuit breakers are on.
- Check that the outdoor unit’s disconnect switch is on.
- Make sure the blower motor is running.
- Check for error codes on the thermostat or control panel. You can refer to the furnace’s manual to interpret these codes.
Is there a reset button on Bryant’s furnace?
Not all Bryant furnace models are equipped with a reset button; however, a significant number do feature one. Typically, the reset button can be found either on the burner assembly or in close proximity to the motor of the furnace.
Why Does Your Furnace Need To Be Reset?
There are a variety of reasons why your furnace might be in need of a reset. Let’s explore some possible causes:
- Overheating: If your furnace runs too hot, it will trigger a safety shut-off to prevent any damage. To restore normal operation, allow the furnace to cool down and then perform a reset.
- Empty Fuel Supply: A lack of fuel means your furnace cannot produce heat. Refilling the fuel tank and resetting the system will typically get your furnace back on track.
- Closed Gas Valve: If the gas valve is shut, it will block the supply of fuel. Opening the valve and resetting the furnace can allow gas to flow again, enabling the furnace to restart.
- Malfunctioning Flame Sensor: A faulty flame sensor can cause the furnace to shut off as a safety precaution. Resetting the furnace may help to clear any issues related to the sensor.
- Electrical Issues: Power outages or surges can disrupt the operation of your furnace. A simple reset can help restore normal functioning after such incidents.
Tips for Ensuring a Successful Reset
- Check for Error Codes: Many Bryant furnaces have LED indicators on the control board. If the furnace doesn’t start after resetting, look for blinking error codes and consult the user manual to diagnose the problem.
- Inspect the Air Filter: A clogged air filter can cause furnace issues, such as reduced airflow or overheating. Replace dirty filters before attempting to reset the furnace.
- Ensure Gas Supply: For gas furnaces, ensure the gas supply is turned on and there are no blockages in the gas line.
When to Call a Professional
If the furnace does not restart after a reset or continues to shut down repeatedly, contact an HVAC technician. Persistent issues may indicate:
- A faulty control board.
- Problems with the flame sensor or igniter.
- Gas supply issues.
- Mechanical failures in the blower motor or heat exchanger.
Following this step-by-step process and considering the additional tips, you can safely reset your Bryant furnace and address minor operational issues. If the problem persists, professional assistance is recommended.
