It could be dirt on contacts. Could try to use some canned air to blow out the switch. Disconnect power first to be on safe side!
What is make and model of your transfer switch? If I remember there was some recalls on some!
recall
The recall was for improper torque on the 120 mount screws. It was a OEM install issue, not a fault with the Transfer switches. It was a fire hazard. Doug
