I have a levitron 10/20/30/60 timer in the bathroom for our

Customer Question

Hi Mike - I have a levitron 10/20/30/60 timer in the bathroom for our heat/exhaust fan. It is about 2 years old, rarely used. It just started buzzing - althought the buzz lessons the longer the fan is running. We have not tripped electricity, so I am assuming it is the unit. I didn't know if it was just a loose wire or we the whole thing had to be replaced?
JA: Did you double-check the thermostat? And what about the unit's filters?
Customer: the fan works perfectly fine. the buzz is coming from the wall where the levitron timer is located. The fan is in the ceiling
JA: Do you plan on doing the work yourself?
Customer: It depends. I thought I would go an get another timer. Who installs it is not clear yet.
JA: Anything else we should know to help you best?
Customer: i just want to make sure that the noise (although unpleasant) is not dangerous? I don't want to spark a fire or anything

Most times that noise is the result of a loose connection. It is a sound of arcing. If the wires are tightly connected it is bad contacts in the timer and it need to be replaced.

before i replace it I could check first to see if there is loose connection? It is dangerous to keep using it while it buzzes?

If arcing it will cause additional damage. Check it out as soon as possible.
