Goodman, Amana APG13 error code 7 flashes

Limit opened five times in the same call for heat

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

Amana APG13 is 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.

Amana APG13

Needs attention soon

Quick answer

On Goodman APG13 (2000s), 7 flashes is a fault. It means limit opened five times in the same call for heat. A first thing to check: Restricted airflow over the outdoor coil, from dirt, debris or blocked condenser.

Applies to: Goodman APG13; Goodman and Amana APG13, GPG13, APG15 combined furnace and AC flash codes · Furnace · 2000s
Type of code: Fault; Urgency: Needs attention soon
First safe check: Look at the outdoor coil. If the fins are packed with cottonwood, grass or a fine grey fuzz of dust, that alone can cause this.

What 7 flashes means on this model

The heat pump has hit its high pressure limit five times in a single call for heat. Five times is the point where the control assumes something is genuinely wrong rather than a momentary condition, and it stops. Cooling often still works, which is why people run the unit in summer without realising the heating side is dead.

Symptoms you will notice

Heating mode runs briefly, then shuts down
House is cold even though the thermostat is calling for heat
Cooling still works normally
Code appears after several minutes of heating

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:

Restricted airflow over the outdoor coil, from dirt, debris or blocked condenser
Failed outdoor fan motor, so the coil does not shed heat
Low or lost refrigerant charge
Failed high pressure switch
Stuck reversing valve
Restricted metering device

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 outdoor coil. If the fins are packed with cottonwood, grass or a fine grey fuzz of dust, that alone can cause this.
Confirm the outdoor fan is spinning freely and at speed.
Check the air filter. A restricted indoor airflow raises head pressure on the heating cycle.

Do not do these

×Do not keep calling for heat. Each attempt pushes high pressure into a system that may already be low on charge.
×Do not clean the coil with a pressure washer, which bends the fins.

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 coil and changing a filter are fine. Anything touching refrigerant needs a licensed technician.

What it costs to fix

Parts

Capacitor $25 to $60. High pressure switch $50 to $150. Charge $150 to $400 including labour. Reversing valve $250 to $600.

Labor

Two to four hours depending on what is actually wrong.
