Goodman Furnace E2 Error Code: Rollout Switch Open

Quick Answer

Goodman E2 is one of the most serious furnace fault codes. The rollout switch is a one-time thermal safety device located near the top of the burner assembly. When flames roll out of the combustion box - due to a cracked heat exchanger, blocked flue, or overfire condition - the rollout switch trips and locks out the furnace permanently until manually reset. The critical point: never reset and restart without finding and fixing the root cause. Rollout indicates a fire hazard. The switch requires a physical press of its button to reset, and pressing it on a cracked heat exchanger buys only until the next cycle.

What Does the E2 Code Mean?

E2 is a rollout fault: flames escaped the combustion chamber. This is a serious safety event. Do not reset and restart until a licensed technician confirms the heat exchanger is intact and the flue is clear.

Most Likely Causes

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

Cracked or failed heat exchanger allowing combustion gases to escape40%

Blocked flue or exhaust vent backing combustion gases into the cabinet24%

Severely dirty burners causing flame impingement22%

Overfire condition from gas pressure set too high14%

Symptoms You May Notice

Furnace hard-locked out with E2 code
Visible scorch marks around the burner assembly
Smell of burning inside the furnace cabinet
Rollout switch button visibly tripped (popped out)
Furnace runs briefly then shuts off

Can you reset a Goodman furnace to clear the E2 code?

E2 requires a physical manual reset of the rollout switch - it will not clear via a power cycle. Locate the rollout switch on the burner assembly and press its reset button firmly until it clicks. Only do this after the root cause has been identified and corrected by a licensed HVAC technician. A recurring E2 after reset means the root cause was not fixed.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Turn off the furnace at the power switch and close the gas

Turn off the furnace at the power switch and close the gas shutoff valve immediately. Do not attempt to restart. Locate the rollout switch on the burner assembly - it is a small disc-shaped device with a button on top. Note whether the button is popped out (tripped state).

Inspect the flue vent pipe from the furnace to the exterior

Inspect the heat exchanger by visual inspection through the

After root cause is repaired and confirmed safe by a licensed

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Can I just press the rollout switch button and restart my Goodman furnace?

Technically yes, but you should not do it without first identifying why it tripped. Pressing the reset button without fixing the root cause means the furnace will run until it trips again - possibly causing a fire if a cracked heat exchanger is allowing carbon monoxide and combustion gases into the living space. A licensed HVAC technician must inspect the heat exchanger and flue before restart.

What does a cracked heat exchanger mean for my furnace?

A cracked heat exchanger is a serious safety issue because combustion gases including carbon monoxide can leak into the air distribution system and be blown into the living space. On furnaces over 15 years old, replacement of the entire furnace is usually more cost-effective than heat exchanger replacement alone.

Where is the rollout switch on a Goodman GMVC96?

The rollout switch is a disc-shaped thermal device with a small center reset button, mounted on the burner support bracket near the top of the burner assembly. Remove the lower access panel to access it. There may be two switches on two-stage models.
