MA-T51 cycles fan

I'm using an MA-T51 as a timer for an exhaust fan: Panasonic FV-0511VQ1.
Any time selected or full-on setting causes the fan to cycle on and off repeatedly. I used another Lutron timer with the same results. I used an ordinary switch and the fan works properly. Anyone have an answer for me please?

I had the same problem with the MA-T51 timer with the Panasonic fans I just installed throughout our new build house.

Someone on these threads suggested the MA-T51MN and they work like a charm.
