Whether it’s a minor glitch or a more serious issue, addressing it promptly can prevent further inconvenience and potentially costly repairs.
Understanding the Goodman Furnace Solid Red Light
The solid red light on your Goodman furnace’s control board is a visual indicator that communicates various issues.
It serves as a diagnostic tool, helping homeowners and technicians identify potential problems with the heating system.
What does it indicate?
Typically, a solid red light on a Goodman furnace indicates that the furnace is receiving power but is not proceeding with the ignition sequence or heating process as expected. This could be due to several underlying reasons that require troubleshooting.
Common Causes of Goodman Furnace Solid Red Light On But Furnace Not Working
Several common issues could prevent your Goodman furnace from functioning properly when the red light is on:
Lack of power supply
Sometimes, the furnace may not receive adequate power due to electrical issues such as tripped breakers or blown fuses. This can cause the furnace to display a red light and fail to start.
Thermostat issues
Incorrect thermostat settings or a malfunctioning thermostat can prevent the furnace from turning on when needed. This often leads to the red light showing on the control board.
Ignition problems
Issues with the ignition system, such as a faulty igniter or gas valve, can prevent the furnace from igniting and producing heat. This is a common cause when the red light stays on.
Clogged air filters
Dirty or clogged air filters restrict airflow, causing the furnace to overheat and shut down as a safety measure. This can trigger the red light on the control board.
Troubleshooting Steps
If your Goodman furnace’s red light is on but the furnace is not heating, here are steps you can take to troubleshoot the issue:
Check the power supply
Ensure that the furnace is receiving power by checking the circuit breaker and ensuring it hasn’t tripped. Replace blown fuses if necessary.
Inspect the thermostat settings
Verify that the thermostat is set to heat mode and is set to a temperature that should trigger the furnace to turn on. Replace the batteries if it’s a battery-operated thermostat.
Verify the ignition system
Inspect the furnace’s ignition system, including the igniter and gas valve. Clean the igniter if it appears dirty or corroded. Ensure the gas valve is open and functioning correctly.
Clean or replace air filters
Inspect the furnace’s air filters and replace them if they are dirty or clogged. This simple step can often resolve issues with airflow and overheating.
