Burning smell in in dryer

The loud, constant squeak/squeal from your Frigidaire dryer, combined with a burning smell, indicates a serious problem that needs to be addressed. While replacing the drum bearing kit was a good step, it appears that there may be other issues at play.
One possible cause of the squeaking could be a worn or damaged drive belt or idler pulley. If the idler pulley spring came off, it is possible that the belt is not properly tensioned and may be slipping or rubbing against the drum, causing the squeaking noise. Additionally, a slipping belt can generate a burning smell as it heats up from the friction.
Another possible cause of the burning smell could be a malfunctioning heating element, which may be overheating the dryer and causing the burning odor.
It is recommended that you stop using the dryer immediately and unplug it from the power source. It is not safe to continue using a dryer that is producing a burning smell.

Unfortunately, without a picture of the symbol you are describing, it is difficult to give a precise answer. However, based on your description of the symbol and the accompanying burning plastic smell, it is possible that the symbol is indicating an issue with the dryer's motor or belt. The symbol you are describing with the oval and arrows could indicate a rotating part, such as a drum or belt, and the smell of burning plastic suggests that something in the motor or belt may have overheated and melted.
It is important to immediately stop using the dryer and unplug it from the electrical outlet until you can determine the cause of the issue and make any necessary repairs. It may be best to contact a professional technician or LG customer service for further assistance and to avoid causing any further damage to the dryer.

The rubber drive belt is burning up most likely cause by bearing going. The bearings are your ratteling sound and the burning smell is the rubber belt dragging.

scary, is it like rubber or plastic?
rubber would be belt or drum rollers
plastic would be wiring (possible fire hazard)!!!

you got a roller or belt idler not turning and burning the drum belt. you have to take the dryer apart and find the problem. if you need to lubricate a roller or idler use mineral oil or roller oil, do not use wd-40 or 3 in one.

burning rubber smell means the belt is slipping, needs to be replaced

the burning smell may be caused by a belt some have a look at the belt

Your drive belt may have broken if it smelled like rubber burning. If that is the case then your motor bearing are worn out or something has been lodged between your dryer drum and the dryer housing. If the smell was the odor of burning plastic, then your motor is probably burned up.

sounds like you need a new belt for your dryer, the smell of burning rubber is the belt slipping, thats my guess

Sounds like your drier is over loaded. Belt slipping due to : to much weight in drier. The drier motor is an adjustable. Belt test: If you can twist belt more than a half a turn it is to lose. Replace belt.
