Ths Panasonic exhaust fan was on a Leviton countdown timer that had started buzzing and had to be replaced. The fan is rated at 2.7 amps. I put an MA-T51 timer on it and the timer failed to start the fan (or maybe it's switching on and off so rapidly the blades never move?). The Fan's LED light is on a different switch. The timer controls only the fan. Any ideas?
