Question about Heating & Cooling

Strong ''burning plastic'' type smell coming through heating ducts.

Almost an identical problem to stbarresi although flow doesn't appear to be affected. Strong smell coming from the ducts is like a burning plastic smell. Unit seems to be working ok otherwise.

It sounds like you have a main air movement system motor that is burning out. it will probably quit on you in the next few days. likely cost to repair from company 375-700 somtimes more if you have a variable speed furnace, in which case you should consider replacing the whole furnace for what it would cost for the motor on one of those.

My BaByliss blow dryer smells like burnt when I turn it on and I seen like a spark is it going to work anymore


DRYER SMELLS LIKE BURNING:

Answer:First, Stop using your dryer until this problem is resolved. This is a fire hazard and could cause a fire.
Your issue is more than likely alint build up problem. The lint that comes off of your clothes as you dry them becomes trapped in the dryer itself and in the venting duct that connects from the back of the dryer to the wall.
The first thing to do is todisconnect powerby unplugging the dryer cord from the wall. Slide the dryer away from the wall slowly.Remove the hose ductthat attaches to the back of the dryer. Look inside the hose duct and if you see heavy lint build up, that is most likely your problem. If you have a shop vac vacuum or similar, use the long wand attachment tovacuum out the lintthat is in the duct. The best way to do this is to completely remove the vent duct from the wall and dryer.Vacuum the inside of the ductto clean it out. Alsovacuum in the vent hole in the wallwhere the duct attaches to the wall and remove any lint that may be blocking air flow. Put everything back together and test your dryer to see if the burning smell has been resolved.


NOTE: There may be heavy build up of lint deep in the wall. You can purchase aDryer Vent Cleaning Kitthat may make your job of cleaning the vent much easier. However, it may be best to call a Dryer Vent Cleaning Company as they have the equipment that is needed to remove all lint in the wall that could cause a fire. We know everyone wants to save money and "do it yourself" but when it comes to safety, money should not be an issue.
If the burning smell is still present, you cantake the dryer apartandtry vacuuming out any lintthat may be built up on the inside of the dryer. Do a search for your dryer model name and number onGoogleto see how your particular dryer model is disassembled. If you are not comfortable taking your dryer apart then it is advised to call an appliance repair company as your issue can cause a fire.
There are other reasons for your dryer to have a burning smell. There could be an electrical issue inside your dryer. This may mean that a certain part or electrical board is going bad or is bad. Another common reason for this issue is something is near the heating element inside the dryer and causing the burning smell. If you have an older clothes dryer, it may be possible that the components are past its life span and it is time to purchase a new dryer. If you want your dryer to be looked at by a professional, it may be time to call an appliance repair company to come out and check your dryer.
There are plenty of videos that can help you to determine what may be wrong with your dryer. There are a few videos below that may assist you with troubleshooting and disassembling your dryer.
The belt
In some dryers, a belt turns the drum. This belt can slip off, which can cause it to start melting. Because it is usually made of rubber, it will then produce a very strong, unpleasant burning odor. If your drum is not turning smoothly or properly, and you notice a bad burning smell, your belt is probably damaged.
THE MOTOR
Dryers have motors, and as they age, they can burn out just like any other motor. This causes a very strong burning smell, and your dryer will either not run at all, or it will run poorly and with a lot of noise.

There's a slight burning smell coming from the dryer drum.


Some item may have gotten between the drum that rotates and the housing and during the rolling of the drum this item may be heating up from the friction. Check closely to see if you can find anything rubbing on the drum.

Burning plastic smell from under hood


You will need to check where the liquid is coming from, It may be anything from Air Con, Fuel, Transmission Fluid etc..

The fact you smell burning plastic could be 3 things..

1, Brake pads could smell and burn down if they are on too tight (Had this problem with a trailer). Hence when you apply the brakes it could be squirting brake fluid out due to too much pressure.
- Check brake fluid

2, If the smell and liquid is inside the car (front pass side) it could be the air ducts. Under the dashboard you have air ducts etc for the fans and in car cooling (brother had issue with this)

3, Whatever the fluid is, it could possibly drip onto something hot, unusual for liquid to smell like plastic though, Auto transmission oil smells like fish.

Best bet would be the brakes. Next time you smell it just smell in the wheel mag and see if you can smell it, check the engine fluids often and dont use A/C (Air Con) as that does drip fluid (normal). If it is the brakes smelling you will need to have the lines bled out, tyre places may be able to do this, and possibly new brake pads

Good luck

My hotpoint washing machine won't turn on and when turning knob to on position a strong odor of burning plastic comes out from under it


The burning plastic smell sounds like your belt is worn and the drive motor is heating up to the point where it is melting the plastic. You should make sure the power is off and check the belts, transmission, clutch, and drive motor.

Replaced bad thermal cutoff on Whirlpool dryer LEC6848an with new kit FSP 279769 (cutoff & t-stat). Also, cleaned duct, vent, chute, etc. Heats now, but had to shut it off after a few seconds due to...


It is common to have a slight burning smell in the dryer immediately following a clean and inspect of the cabinet. Although you may have cleaned the dryer cabinet interior and the ventilation ducting, dust particles often get stirred up and will settle on the heating element. These small particles will eventually burn off and should not create any hazards to the operation of the appliance. Allow to run for a few minutes and monitor. The smell should go away.

When I turn on the heat there is a strong smell coming through the vents, though the smell is not there when the heat is off.


Assuming it's not a chemical smell, it sounds like a mouse crawled up in your heater and die or made a nest and the young died or you had a slight leak and it's molding. The reason you wouldn't smell it with the heat off is the duct is closed off completely when the heat is off. Unfortunately the only way I know to fix this is to pull the heater core and duct work and clean it out. If you do it yourself is quite a job. If you have a shop do it, it will be expensive.

Strong odor coming from dryer


Usually when there is a strong heat (burn) smell from the heat element, it is telling you that there is poor air flow. This has nothing to do with the model. It is a blocked or restricted vent line, or an internal blower wheel malfunction or a lint blockage further in the machine that is restricting the air flow. WHEN AIR MOVES CORRECTLY, THE ELEMENT HEATS NORMALLY AND DOES NOT GIVE ANY OVERHEAT ODER.

Not getting hot


Check the following to address this issue.




1. No power to the dryer
Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Heating element
A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.

3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.
