Goodman Manufacturing is an American-based company that operates as an independent subsidiary of the Daikin Group. The largest manufacturer of heating, air conditioning, and ventilation systems in the world. Founded back in 1975 in Waller, Texas – they only offered residential cooling and heating systems for the area.
Founded by HVAC dealer Harold V. Goodman the company manufactured flexible air ducts and plastic blade registers. Which was taken to another level when Harold tried to fulfill his dreams of offering an affordable HVAC system for households around the world. However, it was not until 1982 that the company entered the HVAC market and expanded its product offerings.
Goodman might be a high-ranking company, but from time to time customers have complained about system errors. Fortunately, most of these errors can be fixed on your own. So rather than ignoring the error codes, your appliance is showing its time to note down the Goodman air conditioner error code and get to the bottom of the problem. To help you out we have listed down the most common error codes of Goodman air conditioners.

Digital Board Diagnostics
If a failure is detected on the digital board, there will be a green light constantly lit up. This light is located under the OFF touch pad button. The board will need to enter in the Diagnostic Mode to determine failure code and procedures to follow to correct problem.
Diagnostic Maintenance & Status Report
The Diagnostic Maintenance & Status Report Mode provides detailed information on PTAC control operation and operational status including present modes, failures, airflow restriction warnings, operating temperatures, and past failures. The lower right hand dot on the center display flashes in this mode. In some cases the green LED located in the lower left hand corner of the touchpad below the OFF key will also be lit. This Green LED “Status Light“ only illuminates if there is an status code that has been activated and should be reviewed. In most cases, this light indicates that the indoor room filter is dirty should be cleaned or replaced.
NOTE: Dirty filters cause the unit to consume more energy than normally needed to condition a room. Once the filter has been cleaned or replaced, the LED should go out. If the LED is still illuminated after the filter has been cleaned, activate the Diagnostic and Status mode to view any active codes. The unit may need additional cleaning or maintenance of the evaporator or condenser coils. Please perform this step before calling a servicer. A servicer should be called only if cleaning the filter or coils does not clear the status code or the code indicates that servicer should be called.

I keep getting blower error when blows heat or air conditioning. The error #is b3. What’s causing this it’s been doing it sincere about 5 years now
Hello, had a brand new Goodman heat pump GSZC16036 heat pump and air handler AVPTC37C installed yesterday in FL and unit powered up and ran just fine for a minute, then received error code “A05 FAn” flashing in red. Can’t find anywhere what this code means. Can someone please help me? Thank you in advance!
I have a new variable speed goodman 5ton AC and handler.
Goodman can’t answer the code that is flashing nor can anyone else I’ve talked to.
3green flashes so communicating well then FAn blinks for fan on then blinks AOE? Anyone know what the heck this means?
Hello…
I keep getting an error code on my Goodman A/C unit of L2 or HC01, and the unit fails to run. When I toggle the main circuit breaker for the unit, it comes back on. Any ideas on where the problem is? Thanks.
i Have purchased a 18 seer goodman 3ton last week. Had it installed by installer . I went out checked it the other day . It seemed to be defrosting frequent . So i pulled cover it is showing a A-2 code . book said it is a open outdoor air sensor . Ok now i seen a plug with two black wires not plugged to board , could this be the problem.
