I bought 2 Decora electronic timer switches to to replace wall switches for exhaust fans in my bathrooms. I installed the first one no problems. When I installed the second switch the exhaust fan motor just buzzes. The fan does not move. There are only two wires plus a ground so I tried switching the two wires but same result. I tried installing the timer switch on the bathroom lights and it worked fine. I reconnected the original wall switch to the exhaust fan and the fan works fine again. I thought I had a defective switch so I returned it and got another. Just tried again and same result.
Any thoughts would be appreciated.

What is the part number of your timer? Decora is made by Leviton, If yours is the # 6560M, then it can handle only 500 watts of incandescent lamp, and no motors. Only their 6200 series can handle motors.

It's a Leviton Decora 6515M. I installed the same model on my other exhaust fan and it works fine. Thanks for your help.

From www.Leviton.com

Catalog #: 6515M-I
UPC# 07847784391

500W, 120 Volt AC 60Hz, Single-Pole, Decora, Four Preset 2-5-10-15 Minutes, Electronic, Incandescent Only Timer, Neutral Not Required - Ivory

Even thou one works, the timer is not rated for fans. Sure some will work, but expect problems if it is left as is.

Thanks for the help. I have ordered the correct timers. I guess I will use these one on some lights in the house.

So looking at the Leviton 6200 series of preset timers, I see that they are all rated 20A. Does this mean that you can't (or shouldn't) use them on a circuit with a 15A breaker that uses 14-2 wire?

That is the maximum rating of the timer switch, using it on a 15A branch circuit will not be a problem. If the load to the switch is in excess of the 15A breaker rating or there is a fault current, the breaker will trip to protect the wiring. Nm
