The weird noise is the little motor inside turning the stack of gears that turn the dial. Intermatic mechanical timers have always made that funny noise. They get louder as they get older. When it stops making noise, you know you need a new timer motor.
My next WH timer will use a harbor freight digital timer, and a 40A double throw contactor with a 120V coil. (my current WH timer uses an intermatic 120V digital timer which requires a AAA battery which switches current to drive that same 120V contactor). Listening to my WH operate recently, I find it actually runs less than 2 hours most days (within the 4.5 hour window I give it).
