Is RTH6450D clicking noise normal?

Unfortunately, the sound is normal for this particular thermostat. I replaced an older Honeywell with this unit and was amazed that the newer model made such a loud click when calling for chilled air (still summer here). Since the thermostat is in my hallway, I am sure the click is louder due to the echo off the walls. But heck ... my "old" thermostat was so silent that I had to lean in to hear the relay pick. Actually looking at tossing this one for something quieter and with more features perhaps. I am not going to talk to my thermostat from my phone but I would like to have the outside air temp displayed. So ... quiet its not. Unfortunately, the sound is normal for this particular thermostat.

Clicking noise (small) occurs when signal received to either turn A/C or heat on or off. Noise not prominent nor objectionable.

I had the same noise with mine. Couldn't figure out why. It stopped when I upgraded to the Nest Thermostat.

When you switch the heating or the cooling on or off it will make a brief not very loud clicking noise.

no its actually a pretty loud click. my wife has asked a few times, "what's that noise?" We've gotten used to it.

I just purchased the Sony HT-7000DH and hear a clicking sound. Were you able to fix this problem? I may end up returning this product.

Hi, I'm going to say it is not normal, I have two and neither one makes any noise opening. Also think about all the doors you've opened, they shouldn't make abnormal noises. It should be covered by warranty, good luck, Larry

It made a clicking sound when I tried it. Not sure if you'll have the same experience.

My Robertshaw RS6110 thermostat and have never heard any clicking sounds...maybe you should have an electrician check it out.

I mounted mine directly to the inside of the cabinet, and the noise is just a small clicking sound once every several seconds. It is only noticeable when it is quiet and you are standing near the pump.

No idea, check your install and make sure it's well supported, mine has no noise like that.

It's a plug and play... I didn't have to change any setting. Mine did the clicking sound as well but it worked fine. I wouldn't know if it still works cause I lost it.

Mine makes sort of a click noise but that is it. Mine is several years old though so guess they could of changed it. Very reliable little fan though!

Yes. I think it is normal. Mine does the same thing. Unfortunately the manual doesn't bother to mention it.

Mine will make an audible clicking noise whenever the system starts up or shuts down. I'm guessing it is something inside completing the circuit allowing the system to run.

I can hear the clicks on mine if the ambient noise level is low. The clicks are quite subdued. I have 18 of these in service.

Hi Sue, I don't hear any clicking noises while its cycling cold/hot/cold. The unit is made of a few different kinds of metals and they probably contract and expand at different rates. The clicking might be the different parts subtly moving aginst each other, or the fry pan could just be haunted.

I've had an R835 since issued -and prior Portegés- and have never gotten any clicking noises. The only thing I hear is the occasional, yet-quiet fan hum.

I have had the product for several years now & I have never heard clicking sound coming from it. Sounds like there might be something wrong with it. It's never given me any problems other than having to change batteries from time to time.
