Goodman Furnace Troubleshooting Tips

Goodman Furnace Troubleshooting Tips

Reputed furnace manufacturers install unique features and settings in their appliances for maximum comfort of their customers. Goodman manufactures have one of the best features to help furnace owners know something is wrong with their furnaces.

If you own a Goodman furnace or have owned one in the past, you know you can identify several furnace problems with the help of the small blinking light that flashes at the time of issues. If you notice that the blinking light is flashing six times rapidly, here is what you should do before contacting a professional technician for emergency heating repair in Lancaster. 

Effective Troubleshooting Tips

1. Unplugging The Furnace

Before anything else, ensure that you break the power supply to the furnace for safety reasons. You would not want to get an electric shock while fixing your furnace, so the safest option is to remove the plug of the furnace from the outlet and proceed.

2. Inspect The Power Cord

By inspecting the power cord, you ensure that the power cord goes into an outlet with at least 115 volts of power. Most of the outlets in a home have more than 120 volts of power, but you should check this before proceeding. If you are not sure about the power supply of your outlet, you can contact a technician.

3. Remove Other Appliances

If other appliances are connected to that outlet, remove them and keep them elsewhere. A light that rapidly blinks six times means an unexpected switch in the power volt polarity. Removing external appliances connected to that outlet can help fix this issue.

4. Reset The Circuit Breaker

Since this issue involves a shift in the power volt polarity, you can take extra safety measures by replacing the circuit breaker of your furnace with a new one. It would ensure that the power volt polarity does not face any shift in the future.

5. Inspect Air Registers

You may feel that this step is not as important as the other steps, but you should follow it for better safety and security. Inspect the air registers of your home before you resume using your furnace. Ensure there are no blockages in those registers that may hamper its working. After following all these steps successfully, you can try resuming your furnace.

If everything goes well, the light will stop blinking, and your furnace will work as it used to. However, if the light continues blinking, you should contact a professional technician to look into the matter instead of following these steps again. There is a high chance that your furnace is facing issues other than a shift in the power volt polarity. 


The blinking light indicates several problems other than shifting power volt polarity. You can fix some of these issues, while others require immediate professional attention.
