Does anyone else notice an odor of "electrical overheat or electrical burning" when this unit is in use? I am afraid to leave it on because of this..

I am a blueair 603 user from Beijing, China, which the air quality is the worst all around the world. My 603 is always keeping on going for more than 4 days, non stop. It has been working for 6 months, no electrical overhear or burning happend before.

Nope. The smell was probably from the electronic components on the inside. Mine finally burned out & I replaced the power supply diodes. (I have an electronic background) For a less than industrial grade cleaner this little fellow has given me my money worth. Over a thousand cycles. However it is not sturdy enough to handle extended high time settings. The liquid should get hot, but I think this is the problem for the circuit board; Insufficient cooling on the inside to vent the heat away from the circuit board. I installed a micro pancake cooling fan & have had no further problems on any setting. If you have a friend that is electronic savy this is a simple & cheap modification. Hope this helps Nope.

Hi Jo,I don't know because out unit does't have those smell.Is it brand new? Maybe that's one of the reasons. Let it work for a while and see how it's gonna happen. If it doesn't change at all, you should send it back soon! Hope this help!

One concern: Does any part of the unit feel warm or hot? Run your hand all over the unit. Run your fingers over the electrical cord after it has been running for 30 minutes. Run your fingers around the wall plug. Careful not to tough the prongs. Electrical resistance causes heat. Hence a possible source of your smell. This is not safe. If you feel any of these areas warm or hot disconnect the unit and call a licensed electrician to verify that the wire servicing the wall plug is heavy enough to supply the air conditioning unit. Second suggestion: Pull out both filters. Wash with any bathroom cleaner that contains bleach. Dry with a towel and reinsert.Hope this resolves your issue.

No odors could be a heating element problem unplug the seat. If smell goes away recommend replace could be electric issue.

there may be some plasticky smell off a new unit. that just means it was recently manufactured instead of sitting on shelf for awhile. try letting it run on low for awhile. i just keep mine on overnight. it eventually goes away. if it continues still, ask to exchange.

We vacummed out the where the housing goes. We did not notice a smell. Although when the tv is turned on , we get the notice the lamp is nearing the end of its life and needs replacing.

I have had no issues in my vehicle with any odor. I have the on the inner firewall and inside the hood which gets quite warm. Just use a roller to make sure it sticks. Sounds like a good idea you have.

I noticed a 'burnt odor' emanating from the hair dryer before initial use and was also concerned. After a few weeks of daily operation, the odor's dissipated. We've had our Remington hair dryer for several months now, and there's no unusual odor, just normal from what you'd expect from a very hot heating element.

My heater smelled the first two times i used it. Now when i use it its ok now its the paint burns off a little then it will be ok i love mine you should run it outside first and it will be ok.

Never. I have had mine several years. What kind of smell are you referring to (please clarify). Can't imagine what could even cause a smell in one of these compact units.Personally, I know we have saved money with this unit, while having a constant flow of never ending hot water. We have a home in city, with our ranch and cabin out in the country (where we spend weekends); having hot water on demand (only when we need it) allows us NOT waste money heating water on days we are not even out there. My mother has a much larger unit for her house, she is 100% satisfied with hers.

I have had no trouble with this. No odors or problems caused because of no drain hole.I have 2 units and I would replace with same unit should one quit.Hope this helps.

Hi, Haven't had ours for long enough to have any problems. However, knowing what little I know about electrical heating elements, if it's making noise that's probably not a good sign. Would take the time to send it in either for repair or replacement. These aren't complicated devices, but the potential for fire is always lurking the background. Don't want to overkill, but wouldn't take any chances... Jay Miller

Mine had the odor for maybe a couple days but if you use it frequently, the odor goes away. I try to run it with the "COOL" setting off for a few minutes before shutting it down when I am done with it. That seems to work for me as I haven't had any odor from it for weeks.

my gives off a smell as if you were turning on the stove top for cooking you may want to put in some fresh air as I do have a fresh air pipe right under my unit a 2" pipe, hope this helps you I have had my unit for some years

I get a slight gas odor when it ignites each time it lights. I am hooked up to natural gas which has an abundant amount of odorant. I have a natural gas cooking stove with electronic igniters. with the delayed ignition of the burners I get the same odor. with the heater the burner is quite long compared to the small pilot. I'm guessing with the large amount of gas being pumped out it can't burn all the fumes that quickly. ask your installer and see if he has the same explanation. also as long as there is no excessive amount of carbon monoxide everything should be ok. please advise me on my comments . remember I am not an expert. so ask these questions of your installer and advise if he agrees. I have my heater in a remolded garage converted into a large bathroom, shower and laundry which in itself has a lot of odors. I will be shortly be installing a fan which will hopefully disparate most of the odors. gordy from meriden conn.

Not an electricity expert either but this thing started smelling very burnt and started discoloring after a month plugged into our 120 v so I don't think I'd risk it... We had to throw ours away to avoid an electrical fire. Have you tried the Comfort Zone spray? That might be a better option for you.
