I have Goodman model # GPG1348090M41AA. Back in December the blower motor ran constantly. I'd pull the breaker to shut it off, & when I turn the breaker back on, the blower motor would start right back. I clean the burners & reset the flame rollout switch. I thought that fixed it.
First time i turn A/C it worked fine. When it cut off after reaching the temp, I noticed the blower fan was running. I cut it off at breaker and a couple of days later, I kicked breaker back on with out the blower motor coming on. I had it cut off at the Thermostat a few days later when i noticed the blower motor running. since the cooled normally I just cut the breaker until i needed it to cool. A lock out code was the only code couple days ago. I tinkered with it trying to get the motor to run with no luck. I was about to call a pro, when tonight I happen to notice it running. so I turned it on to cool the house, & the A/C work perfect. when A/C reached it's cut off temp, it shut off but the blower motor had been running.
