why can i hear one of the units making a squeeking noise?

They all make a noise, some are a little louder than others. The noise is supposed to deter the mice.

Honest answer: because they're cheap. They say they're supposed to be inaudible to humans, but they are definitely audible, and to my ears, highly annoying, especially in an otherwise quiet room. I've found that similar units in the $20ish range are much less audible.

We deployed this unit out to a client so its not something that I have daily interaction with. However, I don't recall it being something that stood out to me or if I even noticed any fan noise at all. I know that isn't a great deal of useful information but wanted to get a response back to you.

These t-stats are only rated to run a single heater. You could be overloading it. Try unhooking one and see if the noise goes away

there is also a switch on the side that switches the type of sound you get. that might be the problem.

No, I have 4 diffrent units and one of them beeps! It's very annoying I know and I wish I could stop it! I'm in the same boat as you with the one unit.

Mine isn't silent, but isn't horrible. Sounds like an issue to bring up with manufacturer. They might replace the unit.

No, my unit does NOT make such a sound. I DO think it is faulty. Please return it, ASAP, but be sure you tell them why.

I don't know but I do know that it these units are extremely noisy and I returned it.

Shouldn't be that loud or, going off that frequently. You can perhaps turn the temp a little? I had one unit that made noise, but the new one is pretty quiet.

I'm not sure,for as the other person indicated, the noise the thing makes is so dreadful,one has to shut it off as fast as they can.

I have four units and they do not make noise. It could be the surrounding area that is interfering, try moving the unit to another space that is open and not near wireless equipment.

chirping is from the unit..(or another one near by) not the wires...we replaced 5 old units (about 6 yrs old) recently as one was chirping due to expiration. Until this happened I had no idea they would alert us to replace them. replace the units. Replacing the unit would give you a unit that only sounds when it is an emergency..so changing the unit could save your life as well.

Mine produce a little noise too. Actually,I just bought a second unit and just send it to the technician since it move my left speaker when it turned on.

No. Sounds as if the unit was either installed incorrectly or may be defective.

I do NOT recall any such sounds. I use the unit only occasionally, last a few weeks ago.

This seems to be a common issue with these units. Mine does it also. Wish I had an answer.

I can hear a slight sound on mine, along with the light going off. It seems to take several seconds to reactivate if there is constant movement.
