I have a dual plug timer on my new 10 g riparium set up which is in the living room. Yesterday I noticed the timer is making a pretty loud and annoying whirring sound as it operates. I have never noticed this before. I am wondering if I just did not notice before or if it just did not make the noise before. Is this an issue due to the quality of the timer? I took the less expensive dual plug one at Home Depot. Even then it was not THAT cheap.
Or maybe this is my timer about to explode?
Might look to invest in a digital one if this mechanical one continues making so much noise.
Anyone know anything about this ?
