Nowadays, furnaces monitor numerous elements during and after the combustion process. When the furnace isn’t positioned to begin the ignition for heating or if the system is in an unsafe condition, it will get into a „lockout mode” on its own. Goodman furnaces also fall into this description, and you can solve the issue by resetting the unit. However, first, you need to find the reset button.

First, we must highlight that the reset button’s location will vary by model on every Goodman furnace. Typically, you will have to open up the front panel of your Goodman furnace to access it. In many models, you will find a switch in the air handlers compartment next to the blower motor. With most models, the reset button is yellow or red.
In some models, the reset button is placed next to the limit switch in the furnace’s control panel. The surest way to know where the reset button is on the Goodman furnace is by checking the instruction manual.
We recommend starting by turning the power off to the Goodman furnace at the circuit breaker. It’s not complicated to find the circuit breaker—access the blower wheel and motor and lift the blower compartment cover. You should see a red or yellow button on the blower motor’s side. You need to press the button if you notice it’s popped out.
How Do I Reset My Goodman Furnace?
Let’s highlight that the resetting instructions vary between Goodman furnace models. The following steps to reset the furnace are wide. You should follow the steps only if you don’t troubleshoot the malfunction problem.
1. Start with the thermostat
You shouldn’t just go ahead and reset the furnace, but start by turning the thermostat to the “Off” position. It’s a safe step to take so you don’t cause problems with resetting.
2. Flip de circuit breaker
Continue checking out the circuit breaker and flipping the switch to the furnace. Once you flip the button, you need to move it back in the previous direction. Do it after you wait for 4 or 5 seconds.
3. Remove the access panel
Get a screwdriver and continue unscrewing the screws on the furnace’s front panel. Many Goodman models present two to four screws; check out the front panel’s side to find the screws.
Since the screws are pretty small and you can quickly lose them, we strongly advise you to place them in a secure place. Slide the panel up from the furnace and lift it completely off. Could you set it to the side carefully?
Check out the inside of the furnace. Keep in mind that the location of the reset button varies between models. If you don’t seem to spot the reset button easily, go ahead and look over the instruction manual.
More often than not, the reset button will be placed by the limit switch. After you find the button, press it and hold it down for 5 to 10 seconds.
We strongly recommend reviewing the manual and reading the instructions about resetting the furnace. After resetting the furnace, you might notice a red signal blinking several times until it becomes solid red again. If you see the solid red, you have successfully reset the Goodman furnace.
Extra tips
It’s only necessary to press and hold the red “Reset” button in the middle of the rollout limit switch element. Release the button only after you have controlled it for several seconds.
It would help if you didn’t press the reset button more than three times before troubleshooting the furnace’s internal elements. It’s essential to have at least half an hour between the various resets.
Let’s say your Goodman furnace doesn’t light at the burner level, even though the gas supply is on and the proper ignition has begun. You must turn off the furnace again and let it cool down. You will need to open the access panel and examine the flue pipe system that goes to the pilot light and the burners.
What if your furnace got into lockout mode?
The furnace uses sensors to make a house’s heating system operate. The sensors will also track the pressure on natural gas and the igniter. Some furnaces keep an eye on the ventilation, blower, and elements alike.
The unit will go into lockout mode when an unsafe condition occurs within the furnace to keep the house and system safe. It will do it only after several trials to make the furnace run several ignition cycles. If the furnace enters lockout mode, you must reset it manually. Otherwise, it will no longer run.
Even if the lockout process varies from manufacturer to manufacturer, most furnaces present a simple reset process. You only need to turn the power off the furnace for 30 seconds or more. Afterward, turn the power back on. The interruption in the power supply helps the furnace eliminate the blockages. Continue regularly running the furnace.
We need to highlight that some brands present several lockout reset processes. Some furnaces can be reset by reducing the heat setting on the thermostat for 20 to 30 seconds. You can also find furnaces that can reset independently after one or two hours. The best way is to read the instruction manual for a better understanding.
