    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.

    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.
