ENERLITES 4 Hour Countdown Timer Switch, 5-10-30-60 Min, 2-4 Hour, for Bathroom Fans, Heaters, Lights, Led Indicator, 120Vac 800W, (1 Pack, Ivory)

Why won’t my fan buttons turn fan on but it doesn’t shut off after the set time. the led light turns off after the set time but the fan keeps running.

Does this require a minimum amperage? Our bath fan is 0.2 amps.

The timer function is not working. the fan continues to run after the specified amount of tone until i manually turn it off. how do i fix it?

I need to shut off my AC after 1 hour of use every time it is in use and star again if i put it on again. is it possible?
