Question about Heating & Cooling

1 Answer

This will be our third winter in our home, and for some reason this years when we run the heater it smells. The smell is similar to a stinky bathroom odor (that's the best way I can describe it). I originally just thought it needed to run awhile and the odor would go away, but we have been using the furnace off and on for a few months and the smell has not gone away. We have also changed the filter twice, with no prevail. I am beginning to think the odor is from the basement where the furnace is located. Short of fixing or finishing the entire basement (we rent)- what else can we do?

Contact your Gas company tell them you have a foul smell coming in when you turn on the heater. They typically wont charge for a technician to come out and inspect the heater for you.

Frigidaire Dishwasher smells between washes

We had a similar problem... now once a month we run a cycle with 1/2 clup of bleach... then we run a cycle with just water, then we run a cup of vinegar on the third cycle... That has stopped the smell for us... if we go a few months without doing this it starts to smell again...

Hope this helps

We have a one year old home with PEX pipe and one year old hot water heater fed by a water softener. In one of the bathroom sinks, and only there it seems, there is a sulfur smell when we first open the...

i would check the softener before the water heater, when was the last time you did a back flush of the system? water sitting at the bottom of a water softener tank can get moldy and begin to rot, which causes H2S gas which smells like sulfur , its a breakdown of decay,, this will also happen if your home is using well water,, so check that first , empty the tank and clean it our ,, then back flush the system

Our rinnai avenger 25 gas heater has a gas smell that is overwhelming in our house. Is this a common problem? How and where do we fix it ?

No. it's not common. Or at least not, if it's regularly cleaned and serviced. However, I would caution you that many strong household odors are picked up by the heater and made to smell 50 times worse. If it doesn't smell like rotten eggs, it's not gas you're smelling. It's something else .... have you painted recently or stained the wood work? Have you had the carpeting cleaned or are you burning scented candles while the heater is in operation? All of those things and instances can cause the heater to smell. That's because the heater uses interior air for combustion, so whatever is floating in your household air (dust, lint, pet hair and odors) eventually goes into the heater. If you answered yes to any of the above, stop using the heater (turn the pilot light OFF) for a week or two, until the odor that i's picking up has completely disipated. Paint on the surface may feel dry, but underneath it isn't.

Now, please don't get me wrong. I have been in the hearth and home business for 15 years, now and Vent-free or Flue-less or Ductless heaters are our primary business in the Fall & Winter. They are 99.9% efficient and are totally safe, when properly used and maintained. Over 1 million Vent-free Gas Appliances have been sold and installed worldwide in the past 10 years. There has NEVER been a death related to any of these products. In fact, they have more safety features built-in to them, to shut them down if something goes wrong, than a gas water heater or a Vented heater does.

Now, lets get back to your issue. If in fact, if it is gas you smell and the odor is not caused by the things I listed above, there are a couple of things to look at. Do you only smell the odor when the heater is in operation? Do you smell it with just the pilot light burning? Or with both? How airtight is your home? If it's a recent vintage home and it's really airtight, you may be getting what's called "After Product Burn Smell". This occurs frequently in airtight, new home construction, because there's no air exchange in the house. Unless, you open a door or a window once in a while, to allow fresh air in. Also, the Btu output of your heater (38,400) may be to high for the area you have it in. Unfortunately, it's not a case of one size (Btu Output) heater, fits all.

Other causes for the gas odor can be related to the burner(s) being dirty (incomplete combustion) and needing cleaning. Old gas in the tank or a low level of gas in the tank. The inline gas shutoff valve, not being fully open.

If after reading and troubleshooting all the things I listed and the problem is not solved, you need to contact the dealer you purchased this heater from and have them make a service call to your home.
To help you further, in case you have misplaced your Owner's Manual, I have included a link to it, that you can download and print for future reference.

I hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks.

If it smells like plastic burning. Stop using it immediately. As there could be an electrical short or overheating of the unit. If doesn't smell like plastic burning, you'll need to be more descriptive of what the odor smells like.

You most likely have a leaking heater core. Antifreeze is slimy and stinky, but it is generally green or orange. have a shop take a look at it.

Fowl smell in bathroom

Fowl smells related to plumbing can have several causes. Here's a few potential issues that you can check. If none of them solve the problem you may need to call a plumber.

1) Look at your pedestal sink drain connection. Is there an an elbow connecting to your drain or a P Trap? A p trap is a pipe shaped like the letter "p" (hence the name) and it prevents sewer gas from rising into the bathroom. **sometimes an apprentice plumber puts in a pedestal without a p trap because they are fairly difficult to install, and ALL fixtures need P traps. If there is no P trap, then you need to put one in. It will be a tight space, but you may be able to do it yourself.

2) Do you have a floor drain? If so, your sink will need a trap primer at the drain. Or you can pour water into the drain from time to time before it evaporates from the trap

3) If the smell is more of a sulfur type smell and it appears from running water in other places in the house, then it could also be due the type of tank you have if you are on well water

My offhand guess is that number 1 is your issue.

Without further info, those are some of my best solutions so far, but if none of these are potential solutions, then make the following tests

1) close the door to the bathroom and leave it for an hour or two. Return to the room. Do you smell sewer smell? Is it in the entire room or more concentrated in a certain area? If you don't have a floor drain and its everywhere, there could be a missing P trap from a fixture, a lose toilet flange, a cracked drain pipe
2) without running water, smell your drain. Does it have a sewer smell? Then the P trap either is not present or you need to clean the drain with a drain cleaner due to a list of reasons
3) run water. does the sewer smell increase or does one suddenly appear. Is the smell more a different odor than sewer. See if it is the water itself. If so, check other places. If they do not have the smell then you may have recently installed your sink and there is some smell related to the new valve. Then you would need to use it some more until it disappears.

Check the top list, though because I really think you're just missing a P trap

Sewer breaks below the slab, an open pipe somewhere, some issue with the water supply, are among some other issues but that depends on the test

Windows fog up,small anti-freeze smell

The early sign of a heater core leak is the smell of coolant, the reason is that only vapor is leaking now, it will gradually get worse in most cases and coolant will start comming out the heater box condensation drain.

Stinky washer

I have the same problem. The solution is to use bleach with your whites. It's better to use a normal amount of bleach frequently rather than a lot of bleach only once in a while.

Stinky clothes

I have the same problem - the clothes smell like they have been left in there for a week - stale or moldy.

It only happens with dark clothes - I have started adding color safe bleach or oxy clean and sometimes a tiny spash of bleach - it seems to have solved it.
