Burning smell from AC Unit

Of course it is a sunday night at 11:30 when our AC unit totally turned off, wall display monitor totally blank, and we are smelling a burning smell from the AC Unit. We called our AC service who told us they would be out in the morning. Is that okay??? My husband turned the breaker off in the garage, but we have a 5 year old and a 6 month old and are kind of afraid. I believe the smell is getting better, but any advice?

Seems like you just burned out the fan motor. The smell shouldn't be harmful as long a your home is well ventilate. For more AC tips and advice visit Air Conditioning Fort Lauderdale

"Odor problems can be as serious as a gas leak or as simple as a dirty air filter. But remember, a good mechanic doesn't just use his hands. He uses his ears and nose. Unusual odors could indicate a serious problem and should not be ignored. 

We will go through each of the five categories and list the possible causes and things to check.


1. Electrical odor - Electrical odors are usually caused by parts overheating. Indoor blower motors are a common example. If there is a mechanical failure such as the bearings seizing up, the motor over-heats and the insulation on the wires and the motor windings themselves start to melt, causing the odor. 
Sometimes loose electrical connections cause wires or plastic relays to overheat causing electrical odors. 

It is possible for a very dirty air filter to cause the odor. If the airflow is restricted enough, it could cause electric resistance heaters to overheat, even burn-out. 

If you smell an electrical odor, check your air filter. If it is not blocked, shut off equipment at the breaker if possible and call for service. 


2. Burning odor - This is similar to an electrical odor only worse. It is also sometimes accompanied by smoke. Once again, this can be caused by parts or wiring burning-up. 

It can also be debri such as plastic getting into the ductwork and melting on the electric resistance heaters or heat exchanger. 

If you smell a burning odor, check your air filter. If it is not blocked, shut off equipment at the breaker if possible and call for service.



3. Gas odor - First of all, if you really smell gas and suspect a gas leak, you should open the windows, get out of the house, then call the gas company. 

Now excluding that "worse-case" scenario, if you notice an odor that smells like gas and it seems to be coming out of the supply vents, it usually isn't gas. Sometimes dust that settles on the heat exchanger during the summer months burns off at the beginning of each heating season and it smell just like gas. 

If the odor doesn't seem to be coming from the vents, try to pinpoint where the smell is coming from. Use your nose. If it is gas, it usually would be from a leak in a pipe fitting or at the equipment itself. 

Gas odor is the one that causes the most fear. People think of gas explosions or carbon-monoxide poisoning. Well, gas explosions are very rare and carbon-monoxide for the most part is odorless. 

Having said that though, don't take a gas odor lightly. If you can't locate the source of the odor and you are worried you have a gas leak, remember, open the windows, get out of the house, then call the gas company. 


4. Oil odor - Oil odors are usually caused by one of two things. An oil leak/drip or an oil burner that is not working properly. 

The oil leak is usually easy to spot. Just look for oil. Check the burner itself, the oil tank, filter and oil line. Sometimes it is just a matter of tightening a fitting. If there are no signs of an oil leak then it is most likely a burner problem. 

This can be caused by many things, too many to list. It could be a minor adjustment to the burner to a faulty or blocked chimney. From a bad fuel pump to a plugged oil nozzle. Listen for any unusual rumbling or banging sounds or smoke or soot while the burner is running. If you notice any of these things and/or you have an oil odor, you should call for service immediately. 

One other common problem today is that new houses are insulated so well and are built so tight that they run out of combustion air, causing odor problems. In this case it is just a matter of bringing in a fresh air for the burner. Call your local Heating Company to assist in a proper diagnosis. 


5. Damp and musty odor - This is more common in the air conditioning mode. Sometimes attic units or very damp basements have this problem. Check for air leaks in the return ducts. Check for water damage to the ducts or air handler itself. Possibly consider having your ducts cleaned. Run a dehumidifier and see if the odor goes away. 

But this odor problem is almost never due to a problem with your equipment. 

 


Final Tips:

Keep in mind that almost all heating systems cause an odor the first time they are fired-up. And the first few times at the beginning of each heating season. Brand new furnaces are coated with oil to keep the heat exchangers from rusting. This burns off, creating a bad odor - even smoke. But it usually only lasts for about 20 minutes. Opening the windows usually solves the problem. And the first few times the backup heat on a heat pump kicks on, it smells like an electrical smell. This might last for a few days but isn't that bad. If you are worried, call for service. 

Remember to check for a clean air filter and that your vents are opened. Check to see if the fan is working which mean your motor hasn't burned-up. 

Check for air leaks in damp areas, oil stains or rumbling sounds, strong gas odors - these all indicate problems. Do not ignore them. 

Hope this helps, remember - these are just rough guidelines and not all possible situations are covered."

To make sure that there is not a problem with your blower test it on cool. if it runs good. then start the heater on auto and it should be okay. but still supervise the operation for about 5 mins. if you still smell something burning . then call an AC Technician for help.

You should be able to take the information you have (on the capacitor) to Air Conditioning Supply House and purchase an exact replacement.

As to the diagram. There should be a schematic on the unit - somewhere. Usually located on an 'inside' panel.

Unless someone has removed it - the AC will have a schematic on it.

RV AC unit won't cool, blows chuncks of ice


It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

I would have a tech come out and check the voltage going into the fan relay and fan itself. The smell being as how it is coming through the vents in the house tells me that the problem has got to be at the blower or in the area at the blower fan which leads me to the possibilty that the smell could be the windings on the motor. This could be because the voltage may be to high. Good luck on repairs

Since you have a knob, I am assuming that this unit has manual controls that are mounted directly below the air conditioner on a ceiling pack. If you smell burned wiring, remove the inside shroud to access the 120VAC connections in the unit. Check these connections for OK, if they look burnt, cut them back and reattach them (be sure to turn the breaker off first). Try the AC again.

If those connections look fine, then remove the upper cover from the unit. Access the capacitors on the side of the unit and check them for ok. If any one of them looks burnt, replace it. These two places are usually the only place that you will get a burned plastic smell.

Hope this helps,

Jeff

Bad smell from ac unit in my house


does it smell like literally , dirty socks?if so it is dirty sock syndrome, a plague of heat pumps for years. if it smells like an electrical melting or burning of wires then time to call a pro.it could be a weak capacitor or a weak fan motor. if it is dirty sock syndrome then its the microbes that thrive when temps are middle temps and reproduce when temps are hot and cold in intermittent days. hot one day and cold the next equals call for cool then call for heat and hot steam from heated coils cause s bacteria to grow and microbes to spread across coil. when you switch back it causes the smell.if the coil is clean you can spend a chunk of money on sanitizers but best bet is to run it cool for hot weather and hot for cool weather. the transitional periods are what create the smell. avoid semi cool and semi hot periods. this condition is common to acs from all brands . lots of stuff on the internet about dirty sock syndrome

It sounds like the blower motor has burnt up.(the one inside) The unit running for a few minutes then shutting off, is due to the high pressure/temperature safeties. When you removed the panels, did you notice any fan running?
