Error Code 3 Blinks
A code 3 blinks indicate a problem with the furnace’s fan motor. Here, the OPV is reading a wiring or motor problem. The fan is used to circulate air within your home. To maintain the ideal air quality and temperature, the fan must be operational. If the fan malfunctions and doesn’t work properly, the furnace may show an error code 3 blinks. To troubleshoot this problem, you’ll want to start by examining the fan’s wiring. Next, turn off the furnace and unplug its wiring. Clear away any build-up and replace any damaged wiring. You can also replace the fan motor if it is broken.
Goodman Furnace Error Code 3 and 4 Blinks
Code 3 and 4 blinks indicate a cooling problem in the furnace. Here, the OPV may be sensing a fault in the blower motor, cooling fan, or air intake sensor. This can also occur if you’ve failed to clean the AC filter. To troubleshoot this problem, you’ll want to start with the cooling fan. Check for obstructions and clean away any debris. Next, check the blower motor for signs of damage. If either component is broken, replace it. Lastly, check the air intake sensor for damage. If it is defective, replace it.

You can also replace the control board if it is defective.
