Both electric and gas run dryers contain motors that in turn run both the blower and the dryer drum. If the motor is malfunctioning, it can produce many different types of sounds such as buzzing, humming,, or grinding.
Dryer buzzing can also be caused by problems with a loose or damaged pulley. Careful analysis and troubleshooting can help to determine the cause of your dryer’s annoying and frustrating buzzing sound.
Read on to learn about what is causing your dryer to buzz and how you can resolve the issue.
If your dryer buzzes, disconnect the dryer from its power source. Take off the dryer’s cabinet and locate the drum glides on the front bulkhead. Inspect the drum glides for signs of damage or wear and tear. If the drum glides are worn out, you will have to replace them.
You can also examine the dryer drum’s ball bearings. First, unplug the dryer and make sure that there is no water or any clothing that remains in the dryer drum. Then, go ahead and manually spin the dryer drum and listen to see if there is any buzzing or other noises apparent.
See if you can pull the dryer drum up towards yourself and in all other directions. If you can do this easily, it indicates that you may need to replace the dryer drum bearings.
Also, check to see if your dryer buzzing is caused by defective support rollers and shaft issues. Dryer rollers help support the dryer drum and can eventually wear out from normal wear and tear leading to a constriction of the ability of the dryer drum which causes a loud buzzing, squeaking or thumping sound. If either of the drum rollers or both drum rollers are defective, they probably will need to be replaced.
Dryer Buzzes But Won’t Start
Dryer buzzers are important for giving indications that a drying cycle will be ending soon or that dryer shut off is imminent. If your dryer’s buzzer is simply buzzing but not starting, it is immensely annoying and disturbing because instead of finding nice, clean and dry laundry at the end of a drying cycle, you are left with a nasty, wet mass of soaking wet clothing.
If your dryer buzzes or just buzzes but won’t start, examine the drive belt. Open the access panel and if you put the dryer on its side, you can see if the drive belt has the proper amount of tension or is torn, cracked or is completely broken.
If the drive belt is in good condition, you can tighten it by shifting the motor if necessary.
Dryer Buzzes Then Stops
One of the main reasons for a dryer buzzing and then stopping is a problem with the motor. If the motor has burned out, you can rapidly determine this through several troubleshooting steps.
If your dryer buzzes and then stops, disconnect the power cord and attempt to take off the dryer belt. Then, check the blower fan to see if there are any obstructions. Go ahead and attempt to move the motor shaft with your hands.
If you cannot move the motor shaft manually, you will need to have the dryer motor replaced. This usually will require the services of a qualified and certified dryer service technician.
Dryer Buzzes When Press Start
When you press start and your dryer just buzzes, it can be confusing and disconcerting. Rapid and efficient troubleshooting can usually bring a quick solution as to what is causing this problem and how to fix it.
If your dryer buzzes when you press start, open the dryer door and go ahead and press on the door switch. Then press Start and try to turn the dryer drum with your hand when the dryer begins to buzz. If the dryer starts to run normally, the problem is with the motor.
Dryer Buzzes And Smells Burnt
If your dryer is buzzing at the same time that there is a burning smell, there is most likely a relation between the two things your are experiencing. Your dryer works by the rotation of the dryer drum which is heated. The dryer drum is moved by a rotating drive belt that is connected to the dryer’s motor. If any one of these components are malfunctioning, it could be causing the burning smell and buzzing.
If your dryer buzzes and smells burnt as well, check out the dryer belt to make sure it is not damaged. Also, examine the idler pulley that keeps tension of the dryer belt. You may need to replace the entire idler pulley assembly with a brand new one.
Also examine the dryer drum bearings located on the posterior part of the dryer drum to see if they are worn out and are causing the buzzing noise and burning sensation. If you listen to the back of the dryer, you should be able to identify exactly where the buzzing sound is coming from.
Dryer Making Buzzing Noise While Running
If your dryer is making a buzzing noise while running, it could indicate drum rollers that are simply worn out from use. The drum rollers are located usually on the front or rear or side bulkheads. Examine them carefully to see if this is the cause of this problem.
If your dryer buzzes while running, unplug your dryer and take off the front panel and the drum. Take the drum rollers off from the shaft and check them for any dirt or debris which may be affecting them.
Clean them and if necessary, use some industrial lubricant in order to allow the drum to be able to turn unobstructed. Also check the shaft on which the rollers rotate in order to ensure that they are not damaged or worn out in any way. Both the drum rollers and the shafts on which they rotate can be replaced if need be. This is probably best accomplished by hiring a competent certified dryer technician to reinstall these new component parts.
