My Sunbeam mixmaster junior model-jc is smelling when it runs


the smell will be burning insulation on the windings of the motor probably from the brushes being too short and arcing on the armature thereby overheating the motor. suggest you take it to an appliance repair shop for quote on repairs.

Car was running fine, parked at grocery for 30 minutes, came out started car and it smelled like something burning and now won't idle and is making a strange noise. where should I start ??


Your first concern should be the engine. If it has suffered any internal damage. Try to identify the strange noise and its source. If the engine is still good, check your engine wiring harness carefully. Was the burning smell of an electrical nature? Some wires may have burned-insulation may be bubbled, burnt looking, wires exposed, plastic melted-look for things like that. There may be no trouble codes set from this event, but you should have an engine computer scan just to be sure. Any codes may indicate the problem.
If nothing obvious, you may need a mechanic to check it out. I would want a cylinder compression test done to gauge engine condition before attempted repairs-with 230K on an escort engine (remarkable!), you should want a good idea of the engine's present condition before proceeding.

MIcrowave emits an electrical smell while cooking. It still cooks, but has started emitting an odor recently when in use.


Is the smell ionized (the outside smell of a cold winter morning air) or more of an electronic component burning??? if it's more of an ionized smell it could be normal, (if the smell is strong) it could be a leaking high voltage cable (electric arching) bad insulator, if it's more of an electronic component burning smell, it could be a overheating component, in both cases you should have it checked by a professional technician...

Maytag Neptune Dryer with strong "burned electrical wiring" smell


Sounds like the motor went out. Before trying to start it it needs to be inspected. If you are not comfortable opening up the cabinet then I would would recommend calling a service tech. If you need further assistance please let me know.

GE TFF22RC Side-by Side refrigerator burning smell and no cooling


Sounds like the compressor has gone out or at least the electricals on it. You can replace the relay if that is all it is but at 26 years I would seriously consider replacement. The newer units are more energy efficient and the insulation in your unit has degraded with the years.

Daewoo kor-861h, electrical smell and will not heat.


Turn if off, and leave it alone, remove it, if you can remove the unit, take it in for service, something is wrong if you smell electrical, most people for some reason can smell and identify correctly electrical or at least insulation burning smells, which means something is burning internally, not safe, fire hazard, unit needs to be repaired by qualified technician or replaced with new unit, take no chances, nothing you can do to repair this, could be a shorting transformer, or shorting power cables, but to attempt to trouble shoot this with email is a long shot, and depends on your experience expertize and testing equipment.

I wish I could give you a short easy answer, but the hazard and your safety is more important than a microwave.

Burning smell from AC Unit


http://www.hannabery.com/faq14.shtml

"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."

Burn Smell (electrical) from my GE WPSE4200A0WW


We have the same problem, and found out the the electric motor is running very hot. Replacing the motor seam to cure the problem, but the motor is not inexpensive. $200 to $350.
