Goodman furnace keeps shutting off
Goodman furnaces are one of the most popular gas furnaces in the world, with over 34% global market share.
Goodman manufactures two types of furnaces: packaged and distributed. Packaged units are self-contained and don’t require additional ductwork while distributing units require a separate air handler.
It sounds like the blower is shutting off. The way you can tell is to turn the thermostat down to a much colder setting and wait. If it starts blowing again, the furnace is shutting off because it’s getting too cold for the heater.
If this does not work, you will have to replace your goodman furnace with a new one with a variable-speed blower to maintain an appropriate temperature range.
Goodman furnaces are a popular choice among home owners because they are reliable, affordable and very efficient. However, as with most other heating systems, sometimes they can malfunction.
One of the most common problems that Goodman furnaces face is the circuit breaker keeps shutting off.
If you find that your Goodman furnace is shutting off when it shouldn’t be while running on normal voltage, it is possible that your furnace has a faulty circuit breaker or is experiencing some sort of ground issue in the wiring.

After that, you will want to check all of the wirings for any ground issues or corrosion build-ups and replace anything if necessary.

-Carbon Monoxide Leak Sensor Malfunctioning: This is a common problem that can lead to sudden shutdowns of the furnace. There are two sensors on the unit that need to work for the unit to work, and these sensors can malfunction and cause an emergency shut-off event.
The problem with these sensors is that they are not easy to diagnose without the use of certain tools or experience in working with them.
-Electrical Malfunctions: A faulty wire from the circuit breaker panel may also result in an emergency shutdown the event for your furnace if it’s not fixed promptly.
-The Thermostat is Out of Date/Defective: An older thermostat might not be able to detect excessive temperatures and improperly regulate heating systems, leading them to shut off even when they
