How to Reset a Goodman Furnace and Clear Error Codes

Quick Answer

To reset a Goodman furnace, turn the thermostat off and flip the circuit breaker for 30 seconds before turning it back on. If a rollout switch tripped, press the manual red reset button on the switch. Always record the LED blink code before power cycling as the history may clear.

Resetting a Goodman furnace is usually the first thing you do when it locks out, but here's the thing: if you don't find out WHY it locked out first, you'll just be doing this same reset again in a week. I've watched homeowners flip the breaker six times in a single day instead of just cleaning a $12 flame sensor. Fix the cause first, then reset.

How to Reset Your Goodman Furnace

Goodman furnaces have a three-strikes lockout built into their ignition logic. If the flame sensor's dirty or the ignitor's getting weak, the board shuts down after three failed tries and waits for you to reset it. A power cycle clears the lockout, but the actual problem's still sitting there. If you're resetting this thing more than once a week, something's worn out and it's probably time to replace a part.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Fault code needs to be cleared after repair40%

Transient fault from power fluctuation24%

Post-service board initialization22%

Thermostat miscommunication requiring soft reset14%

Symptoms You May Notice

The LED on the control board is blinking a fault pattern over and over, the burners won't fire, and the furnace either sits completely silent or the inducer hums but nothing happens after that.
You replaced the bad part, turned everything back on, and the furnace is still sitting there ignoring calls from the thermostat because the old fault code is still stored in the board's memory.
The furnace lights and runs for 30-60 seconds then shuts back down and throws the same error code it had before, over and over.
Heat's been out for a couple hours, you go check, and the red LED is flashing a pattern but the furnace won't respond to the thermostat at all.

Did the reset not work?

If the problem comes back after following these steps, a component has permanently failed and needs replacement. Check the specific error code your furnace is showing:

Frequently Asked Questions

How do I reset a Goodman furnace after replacing the ignitor?

A breaker flip usually does the trick, but Goodman's newer boards can be stubborn about it. If the breaker reset doesn't work, try the 3-second hold on the unit's local power switch. Also, make sure the new ignitor isn't touching any metal bracket or surface, because a ground fault will just fire off a new lockout code the second it tries to glow. I always check the flame sensor while I'm in there too, since a dirty sensor will cause another lockout even with a brand new ignitor sitting right next to it.

Why does my Goodman furnace keep showing the same code after I reset it?

Think of the reset like silencing a smoke detector while the kitchen's still on fire. The alarm stops, but nothing's actually better. If a code like F02 for a pressure switch keeps coming back, the board's still seeing an open circuit or a blocked drain or vent line somewhere. You've got to clear the physical blockage in the inducer or condensate drain before the board will accept a permanent clear. Resetting doesn't fix parts. It just restarts the test sequence so the board can fail all over again in the same spot.

How many times is it safe to reset a Goodman furnace?

I have a two-strike rule with these. Reset it once and it runs for two or three weeks, that might've been a fluke, like a power surge or a wind gust hitting the exhaust pipe. But if you're resetting it twice in the same day or twice in the same week, stop. You're probably wearing out the control board's relays, and worse, you might be ignoring a failing limit switch or heat exchanger issue that's way more dangerous and way more expensive to deal with down the road.

Can I reset my Goodman furnace from the thermostat?

You can knock out soft lockouts just by cycling the thermostat mode to OFF for 30 seconds, yeah. But most hard safety lockouts need you to physically go to the furnace. The thermostat can't reach into the board and reset a tripped rollout switch or clear a deep EE code. If the thermostat cycle doesn't fix it after a couple tries, grab your flashlight and head to the unit to read those LED codes directly before you do anything else.

What does it mean when my Goodman furnace resets but then locks out again after a few hours?

That's your furnace telling you something's actually broken, not just glitching. A few hours is enough time to run through a few ignition cycles before whatever's failing causes another lockout. Most commonly it's a flame sensor that's dirty enough to fail about half the time, or an ignitor that's cracking and not glowing consistently. Sometimes it's a pressure switch that sticks open when things heat up. Record that LED blink code before you reset it again. That pattern is your diagnosis, and without it you're just guessing.
