Goodman, Amana ASX13 error code 5 flashes
Open compressor circuit or low incoming voltage
Goodman is the platform name, and your unit may not say it
Amana ASX13 / ASZ13 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.
Quick answer
On Goodman ASX13 (2000s-2010s), 5 flashes is a fault. It means open compressor circuit or low incoming voltage. A first thing to check: Low supply voltage, from a weak breaker, corroded wiring or a long undersized run.

- Urgency: Needs attention soon
- First safe check
- Turn the outdoor disconnect off completely, confirm it is off with a voltage tester, then look at the contactor and terminal lugs for heat damage, melting or green corrosion.
What 5 flashes means on this model
The compressor circuit is open, meaning the control is trying to run the compressor and getting nothing back. Either the supply voltage to the outdoor unit has dropped, or the circuit is broken somewhere between the board and the compressor. Low incoming voltage is the common cause and it damages compressors quietly over time.
Symptoms you will notice
- Outdoor unit will not run
- Fan may run while the compressor does not
- Code appears on every cooling call
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:
- Low supply voltage, from a weak breaker, corroded wiring or a long undersized run
- Failed contactor
- Loose or corroded lug at the contactor or unit terminal
- Failed compressor winding
- Blown fuse in the outdoor unit
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.
- Turn the outdoor disconnect off completely, confirm it is off with a voltage tester, then look at the contactor and terminal lugs for heat damage, melting or green corrosion.
- Check the breaker for a loose connection.
Do not do these
- ×Do not assume the code means the compressor is dead. Voltage problems cause the same code and cost a fraction as much to fix.
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.
- The refrigerant circuit is sealed and legally requires licensed handling. Opening it without certification releases refrigerant and can put the whole system in violation of regulation, so a low-pressure or high-pressure fault on this equipment is a call-out, not a weekend job.
- 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.
Contactor and lug work is reasonable. Compressor work is licensed.
What it costs to fix
Parts
Contactor $25 to $70. Wiring and lugs $20 to $80. Compressor $900 to $2,000. Breaker $40 to $90.
Labor
One to two hours for wiring and contactor work. Half a day for a compressor.
DIY or technician
Contactor and lug work is reasonable. Compressor work is licensed.
