Goodman, Amana, Daikin GMVM96 error code E7

Igniter fault or improper grounding

Goodman is the platform name, and your unit may not say it

Amana AMVM96 / ACVM96, Daikin GMVM96 platform are the same board with a different badge, so this page covers all of them. The fault, the checks and the parts are identical, which is why there is one page rather than one per brand.

Needs attention soon

What E7 means on this model

The igniter circuit failed on this platform, either because the igniter itself is open or cracked, or because current is finding a path to ground it should not. A burner box painted over, corroded, or packed with dirt is enough to cause it, and the fix is cleaning metal and tightening a screw rather than buying a part.

Symptoms you will notice

Furnace will not fire
You hear the blower and nothing else
Igniter makes a faint hum but never glows
Igniter glows for a second then goes dark

Common causes

The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:

Hot surface igniter open or cracked
Loose ground connection at the burner box or igniter screw
Burner box insulated with paint, dirt or corrosion, so current leaks to ground
Failed low voltage fuse
Failed ignition control output or board
Loose or corroded igniter connector

What you can safely check

These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.

Look at the igniter. A working hot surface igniter glows bright orange or white, clearly, within seconds.
Look at the burner box around the igniter screw. It should be clean bare metal. Scrape off paint, rust and dirt and re-tighten the screw.
Check the breaker and the furnace switch.

Do not do these

×Do not touch the igniter with bare fingers. Oils from skin shorten its life noticeably.
×Do not ground the igniter to random metal to make the fault go away. That is how a control board gets destroyed.
×Do not bypass the igniter circuit.

When to call a technician

Book a technician, do not keep resetting it

This fault will not clear on its own. Every power cycle gives the control one more failed attempt, and repeated attempts are what turn a cheap part replacement into a seized or contaminated system.

This is a fuel-burning appliance, so treat anything involving a burner, gas valve or flue as technician work. If you smell gas at any point, leave the property and call the gas utility from outside rather than continuing to diagnose.
If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.

Cleaning a ground connection and replacing an igniter are reasonable for a careful homeowner. Board-level diagnosis is not.

What it costs to fix

Parts

Hot surface igniter $40 to $90. Low voltage fuse under $15. Ignition board $150 to $350.

Labor

One to two hours. Add time if the igniter is inside a sealed combustion burner assembly.
