Hi, I having a problem with air handler. Setup: Goodman GSX130181, Goodman AVPTC 183014, Hunter 44272. It is simple one stage AC, no heat. When I request cooling compressor start spinning, supply pipe gets cold but air handler fan don't start. In one occasion I pulled out fuse on circuit board (under full power), then insert it back, and fan starts. When temperature of air got to requested point, compressor stopped spinning, bur air handler fan continue to blow over 3 minutes( on thermostat auto set for fan). After while I request cold air - compressor started, air handler fan not. I didn't play with fuse anymore.

How long did you allow the outdoor unit to run before determining the air handler fan was not going to come on?
Some air handlers have a delay in bringing on the fan. This delay is normally only about 30 seconds.
