Why is my furnace showing a solid red light?
Red light on Goodman control board: what does it mean? Based on my understanding of the market and research. I have shortlisted some potential reasons why your furnace might be showing a solid red light:
The thermostat issue:
The solid red light, although not explicitly mentioned. It may indicate a problem with the thermostat connection or settings. Accordingly, the furnace is not receiving a signal from the thermostat, which is consistent with the symptom. The result is a single flash of bright light follow to a steady red glow.
Furnace Overheating:
A faulty pressure switch or rollout switch could also flash nine times if it detects overheating. It’d be especially true if the rollout switch detected heat in strange places.
Internal Component Failure:
While less likely, a solid red light could also indicate a more serious internal component failure. This could be anything from a faulty control board to a malfunctioning sensor.
Specific error code:
Some Goodman furnaces may have additional error codes or LED patterns that indicate different problems. Based on the model and configuration, a solid red light can be one of these codes.
It is important to troubleshoot these potential causes to identify and address the problem.
Goodman furnace solid red light stays on or flashes?
The solid red light on your Goodman furnace is like a warning siren. However, what it means depends on how it behaves.
This is a serious situation, like a red flag waving in your face. A steady red light indicates a malfunction on your furnace’s circuit board. Your furnace isn’t operating properly because of this critical component.
Although a flashing red light requires attention, it is less severe than a steady red light. There is a problem with the flame sensor or blower. They ignite the gas and circulate heat, and their problems can affect your furnace’s performance.
In both cases, ignoring the red light is not an option. A technician or DIYer is required.
What are the codes on a Goodman furnace?
Goodman red light codes give your repair specialist a head start on fixing the issue. Let’s break down the common fault codes you might encounter with your Goodman furnace.
Light ON: This indicates that the thermostat isn’t communicating properly. It could be due to a connection issue or a thermostat setting error.
Light OFF: This suggests a control failure, possibly due to power or connection problem.
1 Flash: This means there’s an ignition error, like a dirty flame sensor, a faulty igniter, or an interruption in the gas supply.
2 Flashes: This signals a pressure switch error, which might be caused: a short circuit, a faulty pressure switch, or a draft inducer problem.
3 Flashes: Goodman furnace red light blinking 3 times? There could also be a blockage or disconnection in the pressure switch hose causing this code.
4 Flashes: This indicates an open high limit, which could be due to dirty filters, wiring issues, or a blockage in the flue.
5 Flashes: This code means the flame is sensed when heat is not needed. There could be a leaky or stuck gas valve, or a defective flame sensor that causes the problem.
6 Flashes: This suggests an open rollout switch, possibly due to a blocked or cracked heat exchanger or low gas pressure.
7 Flashes: This code indicates a low flame error, which could be due to low gas pressure.
8 Flashes: This points to an ignitor error, potentially due to a faulty ignitor or wiring issues.
9 Flashes: This code signifies an open pressure switch or a problem with the induced draft blower. It could be due to a cracked or blocked pressure switch hose.
Continuous flashing: This indicates reversed polarity, likely due to a wiring issue.
This will enable you to identify potential issues with your Goodman furnace promptly and inform your service technician for a faster repair.
Goodman furnace solid red troubleshooting: How do I reset my Goodman furnace control board?
Goodman furnace control board resets aren’t recommended as a first-line fix unless advised by a technician. It’s dangerous to misdiagnose the problem.
So How do I reset my Goodman furnace red button? There are a couple of safe power cycling alternatives you can try. That help you to reboot the system without touching the control board:
Power Switch Shutdown:
- Locate the furnace’s dedicated circuit breaker on your electrical panel.

- Turn the breakers back ON. Give the furnace a few minutes to power up and resume normal operation.
Furnace Control Panel Switch (Some Models Only):
Some Goodman models have a manual on/off switch directly on the furnace control panel. Double-check your manual to confirm its presence and location. Turn the switch OFF for at least 30 seconds, then switch it back ON.
Do not hesitate to contact a qualified technician if these remedies do not work:
- Explain the symptoms and error codes displayed, if applicable.
- A professional can safely diagnose the problem and recommend an appropriate repair strategy.
Remember, tampering with the control board can be dangerous, so consult trained professionals. Your safety and furnace operation are top priorities.
