The red light on a Goodman furnace indicates that the circuit board is functioning properly and waiting for a heat signal. If the red light is blinking, it could be due to an ignition failure or other issues with the gas or flame.
This could be caused by a dirty flame sensor or problems with the gas valve or ignitors. Additionally, if the furnace has attempted to ignite multiple times without success, it may enter a lockout mode and the red light will blink.
However, the furnace should reset itself after one hour. It’s also important to check the thermostat settings and connections if the light continues to blink.
Common Causes Of Red Light Blinking
The red light blinking on a Goodman furnace can be caused by various factors. It could indicate an ignition failure, a dirty flame sensor, or a problem with the thermostat. If your furnace has attempted to ignite multiple times without success, it may go into lockout mode, but it will automatically reset after an hour.
Ensure to check the connections and thermostat settings if this happens.
Thermostat Malfunction
A malfunctioning thermostat is a common cause of the red light blinking on a Goodman furnace. This can occur when the thermostat fails to send a signal to the furnace, leading to issues with heat activation.
Flame Sensor Issues
Flame sensor issues can also trigger the red light blinking on a Goodman furnace. Dirty flame sensors or problems with the gas valve and ignitors can lead to faulty flame detection, causing the furnace to signal an error.
Faulty Ignition
Another potential cause of the red light blinking is faulty ignition. Gas-related errors and ignition failures can result in the blinking red light, indicating the need for inspection and potential replacement of ignition components.
Troubleshooting Steps
If your Goodman furnace has a blinking red light, it could indicate a malfunctioning thermostat or an ignition failure. It’s important to check the connection and thermostat settings, as well as the flame sensor and gas valve.

Resetting The Furnace
If your Goodman furnace’s red light is blinking, one of the first troubleshooting steps you can try is resetting the furnace. To do this, follow these simple steps:
- Locate the power switch near your furnace and turn it off.
- Wait for at least 30 seconds to ensure the system fully resets.
- Turn the power switch back on to restart the furnace.
Checking Gas Valve And Ignition
If the red light on your Goodman furnace continues to blink even after resetting, the issue could be related to the gas valve or ignition. To troubleshoot these components, consider the following steps:
- Inspect the gas valve to ensure it is in the open position. If it’s closed, turn it on and wait for a few minutes to see if the furnace ignites.
- If the furnace still does not ignite, inspect the ignitors for any signs of damage or wear. Replace them if necessary.
- Additionally, check the flame sensor for dirt or debris. A dirty flame sensor can often cause the red light to blink. Clean it carefully using a soft cloth or brush.
Inspecting Thermostat Settings
Another potential cause for the blinking red light on your Goodman furnace is an issue with the thermostat. Follow these steps to troubleshoot the thermostat:
- Ensure the thermostat is properly set to the desired temperature. If it is set too low, the furnace may not receive the signal to turn on.
- Check the wiring connections between the thermostat and the furnace. Loose or faulty connections can prevent the thermostat from sending the proper signals.
- If you suspect an issue with the thermostat, consider replacing it or contacting a professional for further assistance.
By following these troubleshooting steps, you can identify and potentially resolve the issue causing the blinking red light on your Goodman furnace. However, if the problem persists or if you are unsure about performing these steps yourself, it is always advisable to consult a professional HVAC technician for assistance.
Understanding Lockout Mode
Understanding lockout mode in a Goodman furnace with a blinking red light indicates an issue that needs attention. The red light signifies that the circuit board is functioning normally but awaiting a heat signal. It could point to problems with the thermostat, ignition failure, dirty flame sensor, gas valve, or loose wire connections.
Understanding Lockout ModeWhen your Goodman furnace’s red light starts blinking, it may indicate lockout mode. This mode is a safety feature that prevents further operation when the system detects a potential issue. Understanding why lockout mode occurs can help you troubleshoot and resolve the problem effectively.Effects of Lockout ModeLockout mode triggers when the furnace fails to ignite after several attempts, usually due to issues with gas supply, ignition components, or airflow.During lockout mode, your furnace will not function, and a single LED flash will blink on and off to signal this status. Your furnace will automatically reset itself after one hour in lockout mode, allowing you to attempt ignition again.Resetting from LockoutTo reset your Goodman furnace from lockout mode, first, ensure there are no ongoing issues like gas supply problems or ignition failures. Once you have addressed any underlying issues, you can reset the furnace by turning off the power to the unit for a few seconds and then turning it back on. This action will reset the system and clear the lockout mode, allowing the furnace to restart normally.Preventing Lockout SituationsTo avoid lockout situations with your Goodman furnace, it is essential to perform regular maintenance, including cleaning or replacing air filters, checking for gas leaks, and ensuring proper ventilation.Additionally, schedule annual professional inspections to detect any potential issues early and prevent lockout mode from occurring unexpectedly.By understanding lockout mode and its implications, you can effectively troubleshoot and resolve issues with your Goodman furnace, ensuring efficient operation and prolonged system lifespan.Expert Advice And Insights
Experiencing a Goodman Furnace blinking red light indicates a code signaling normal board function awaiting a heat call, possibly due to a malfunctioning thermostat. Ignition issues or gas faults can prompt the red light to blink, pointing to flame sensor or gas valve problems.
