The burner knobs make clicking noise when turned but the burners make no sound.

There is no electrical sound in the burner, but the dials for the burner click when turning them.

Yes you can hear it. It must not be working because that little heater puts out a lot of heat!

Some electronic ignitions on the furnace won't work without a pure sine wave. Better check first.

Yes, there is a sound of steam, ( boiling water) and may even shoot out bursts of boiling water. Mine did, and, I had to return it.

Yes I had the same concern regaring a humming sound heard after the water stops flowing. I was told by a tech that it is venting any left over fumes and to clean the unit. There is a procedure to clean the burner unit it's not impossible but it is a little tricky if your not mechanically inclined.

You hear the gas flowing for the pilot light which is a faint airflow sound, like lighting an oven, there's a faint hissing sound at first. That and when it turns the heat on, a faint clicking sound. It's very quiet.

I have not heard any type of unexpected noise froml the warming plate. if the sound you are hearing occurs after/during warming plate heat up, it may not be electrical in nature, but more of a thermal stress release. It this is the case then you can probably feel the movement byhaving your hand on the chassis during the noise event? I am an electrical engineer and if I suspected an electrical arc I would verify it with an AM radio. At the same time of the noise listen to the radio for a corresponding pop in the speaker. Have either an AM standard broadcast or CB radio tuned to a weak or no signal with volume turned up. Sorry if this is a lot more info than you are wanting.

NO the noise is extremely minimal.NOW-after less than a year of which it was used only 3.5 months it started to have a gas smell from within.Energy Co. CKed it and said it was a manufacturing defect.Company would not replace except with a reconditioned one which I had to pay postage on!!It also had the same problem!!!GAVE IT AWAY for scrap!SORRY,BUT,NEVER WILL I RECCOMMEND THIS COMPANY OR ITS PRODUCTS.

Mine does too. Sounded like electronic relays. Somewhat annoying but everything works.

When the fan function is on it makes a fan noise. I don't find it especially loud as far as heater fans go. No beeps. There are two settings: flame and heat, flame heat and fan. So if you don't need the blowing heat it's quiet. However, its a better heater with the fan on.

It could be. You would hear the gas running to start for a little bit but the burners would just not light.

Mine did that too from day one. The box it came in was damaged and I assume that is what caused the weird noises. It wasn't worth the time and money to ship it back so I just used it until it started giving me uneven heat. Then I junked it.

I do hear that noise when the steamer first starts up and is warming but not the entire time I'm using it.

I have the larger model. I have cooked White and GABA brown on this. It is not very loud. There is a low hum while it is cooking/prepping from the internal fan, which sounds like my laptop when it isn't working very hard. If yours sounds like a grinding noise I would suspect that either something is in your fan causing it to grind, or you otherwise have a faulty fan. I don't think there are other components in there which are capable of making loud noises. Unless there is some process of induction cooking for which I am unaware that might cause this.

I do not have a boiling noise however, mine does make a noise like it is on or something but not boiling.

The noise is the water heating inside the water internal hot water tank. Not to worry. The manual addresses that issue.

No noise at all! According to my fiance, if there is buzzing noise, it may not be properly grounded. We replaced the electric heaters all over the house and we are very pleased!
