Why Does My Vacuum Smell Burnt? Ultimate Fix!

Vacuum giving you a burning smell?

Let’s figure out what’s the reason and how to resolve this problem.

Why Does My Vacuum Smell Burnt? Ultimate Fix!

The air fresh from the vacuum cleaner smells burnt, but there is no musty odor in the room. There’s a possibility the vacuum’s motor is broken if this happens. Because of the high temperatures generated by these defects, dust is very flammable. Furthermore, plastic can get quite heated and emit an unpleasant stench.

Why Does My Vacuum Smell Burnt

Overheating caused by a blocked motor filter

While in use, the electric motors of vacuum cleaners can produce a great deal of heat. To avoid damaging the motor, it is also necessary to dissipate this heat. Sucked air is used to cool the engine. The fan’s primary function is to cool the motor with outside air. 

A filter cleans the air before it is drawn into the engine so that any dust or debris that may have been in the air is kept out of the machine. After a while of use, they may get blocked up, preventing air from reaching the engine and cooling it.

That’s why you need to service or replace the car’s air filter (according to the operating instructions). After that, the vacuum’s overheating issue, and therefore, one potential cause of the burnt smell, should be resolved.

A blocked exhaust filter causes overheating.

A blocked exhaust filter might also affect motor cooling. Therefore, you should also inspect the exhaust filter if the vacuum emits a burning smell. It’s often situated near the unit’s exhaust point at the top of the back.

The role of obstructions in heating issues

Overheating and creating a burnt smell can also be caused by a clog in the hose or the suction nozzle. All current vacuum cleaners with motors costing less than fifty pounds have been made so that, depending on the power mode, they deliver a certain amount of air per minute. The engine will attempt to use more power if the air flow rate is too low (for example, owing to blockage). As a result, more heat is generated than can be effectively dispersed.

So, checking all nozzles, hoses, and connectors is essential to see if any debris has gotten stuck in them. If nothing more can be found, look in the dust bag.

Indicators of motor deterioration include a burning odor

A vacuum cleaner will always smell bad, but if you follow the steps above, you should be able to get rid of the smell quickly and easily. In contrast, if the vacuum still emits a burnt smell after following the steps above, it may be due to (early stages of) motor damage. You shouldn’t keep using the vacuum if you notice any problems that could indicate the motor is broken.

Most motor failures, like overheating, are caused by wear and tear or damage from long-term, inappropriate use. Attempting to repair it is usually not a good idea. Most vacuum cleaners and robot vacuums don’t have spare parts or motors that can be bought separately.

Examination in Broad Terms

Pay attention to the beater bar (the spinning component situated at the bottom of the vacuum) so that dust, hair, and string don’t become tangled up in it and cause the vacuum to run more slowly and with less suction power than it should.

Because a clogged beater bar can be a problem if it isn’t fixed quickly, you should always lift the vacuum and flip it over before using it to see if any blockages could make it harder to clean and cause the smell. Next, ensure your vacuum cleaner can move freely about the room; restriction of this movement could contribute to the smoke odor.

Because the filter can become clogged, another helpful tip for avoiding smoke odor is cleaning it regularly. If you’re unsure how often this should be done, consult the manual for your vacuum to see an acceptable interval between cleanings and when a replacement filter should be purchased.

Replace the Belt Correctly

Changing the belt at least once a year is recommended if your vacuum cleaner uses a rubber belt. The rubber belt loses its elasticity and effectiveness over time. But if your belt is made of metal and is part of the assembly of your vacuum cleaner, you should change it when the instructions say.

Metal belts are more durable than rubber ones.

Conclusion

Is this article helpful to you? We hope that you have got the answer to your query, “Why does my vacuum smell burn?” One tactic for dealing with it is not to use your vacuum. What can prevent this if it occurs in most voids over time? Since vacuum cleaners help us keep our homes clean, it makes sense that they should be checked every so often.
