Rather than purchase a new control box ($$) or be without heat/air for a while, owners simply bypass the box or get a tech to bypass until they get a new box or relay later, which sometimes gets put on the back burner and never happens!
Hey Viper, was hoping you would chime in. So if you could help me out, what is the difference in the relay and the driver/relay in the control box? is the control box something located in each unit or in the pump? or something all together separate? thanks!
