Something I wanted to share about these Lennox RTUs. I’ve found many CFM failing or running backwards. Where the line voltage runs through the separations is a potential rub out. The plastic sheeting falls out and cause the rub outs. Might save someone else some time checking them out. Easiest way to check is to disconnect the motor, disconnect the molex inside the cabinet, and check ohm everything to ground. Also for any techs that didn’t know a service wrench works great for set screws on blower and blades.
