DRYER MAKES NOISES.



A loose or worn BELT can make funny noises

Or the idler pulley that puts tension on the dryer drum drive belt could be worn out. If the pulley is bad we recommend also replacing the belt.



The glides on drum worn and making metal to metal contact.

The drum slides or glides support the front of the drum. As the drum rotates over the years, the glides wear out and then the dryer makes noise. Replace all of the glides as a set if they are worn out.



CHECK FOR LOOSE BELLOES inside the drum



Sometimes an item can get stuck inbetween the drum and the housing and scrape and grind making funny noises, things like coins, bra wire, nails, hair pins, etc sometimes u can just remove the cabinet and observe by turning the drum by hand or looking for scratch or scrape marks on housing.



The blower:



Clumps of lint, socks, and other small articles of clothing can get past the lint filter and into the blower wheel. If the dryer makes noise, and the noise seems to be at a very fast pace, there might be something caught in the blower wheel. In addition, the blower wheel sleeve might be worn out, allowing the blower wheel to wobble on the motor shaft. If this happens, replace the blower wheel.



The bearings:

The drum bearing supports the rear of the dryer drum. If the dryer makes noise this bearing might be worn out. Replace the bearing if it is worn out. Do not lubricate the bearing, the lubrication will attract lint and dirt and accelerate the wearing process.

The bearings TEST by moving drum by hand u may be able to feel loose or rough movement. And listen to sounds when turning it.



The drum rollers or castors:



It is very common for dryer drum rollers to wear out. If the dryer makes noise, particularly a loud rumbling noise, one or more of the rollers may be worn out. After removing the drum from the dryer, inspect the rollers.

Check for cracks, dryness, or damage and not engaging drum properly. Sometimes u can use high density LITHIUM BASE gear grease to re oil/grease them.

see this steps and fix it. God bless you

Drive Belt

If the dryer makes noise, the belt may be frayed or damaged. If the belt is damaged, it will make noise every time it travels around the pulleys. The drive belt is a long, narrow band that wraps around the entire drum, then around a tension pulley and the motor pulley.

Drum Roller

It is very common for dryer drum rollers to wear out. If the dryer makes noise, particularly a loud rumbling noise, one or more of the rollers may be worn out. After removing the drum from the dryer, inspect the rollers. If one is worn out replace all of them at the same time as a preventative measure.

Drum Roller Axle

Over time the drum roller axles can wear out, causing the rollers to wobble. If this happens the dryer makes noise. If the dryer is making a rumbling noise, check the rollers and axles. If any are worn out, replace them all at the same time.

Blower Wheel

Clumps of lint, socks, and other small articles of clothing can get past the lint filter and into the blower wheel. If the dryer makes noise, and the noise seems to be at a very fast pace, there might be something caught in the blower wheel. In addition, the blower wheel sleeve might be worn out, allowing the blower wheel to wobble on the motor shaft. If this happens, replace the blower wheel.

Drum Bearing

The drum bearing supports the rear of the dryer drum. If the dryer makes noise this bearing might be worn out. Replace the bearing if it is worn out. Do not lubricate the bearing, the lubrication will attract lint and dirt and accelerate the wearing process.

Drum Support Roller & Axle

It is very common for dryer drum rollers to wear out. If the dryer makes noise, particularly a loud rumbling noise, one or more of the rollers or axles may be worn out. After removing the drum from the dryer, inspect the rollers and axles. If one is worn out replace all of them at the same time as a preventative measure.

Drum Support Bearing

The drum support bearing is at the rear of the drum. If the dryer makes noise check this bearing. If it is worn out, replace the entire bearing.

Drum Slide, Glide, or Pad

The drum slides or glides support the front of the drum. As the drum rotates over the years, the glides wear out and then the dryer makes noise. Replace all of the glides as a set if they are worn out.

Drive Motor

Although not very common, if the dryer makes noise the drive motor may be worn out and the motor bearings can become noisy. If this happens the drive motor must be replaced. The bearings are permanently sealed and cannot be lubricated.

Hello,
The problem with it not drying is most likely going to be a worn out blower wheel thats slipping and not moving the warm air through the clothes to dry them properly. Always a pretty good sign the blower is slipping is,if you hear a rumble noise from the dryer at start up and also that same rumbling noise when the power stops. So if you hear it at start up...wait 30 seconds and open the door and listen for the rumble noise as drum stops. also you can check where the vent exits the house and see if their is air flow when the dryer is running.

GENE

That model of neptune dryer had a problem with the blower housings cracking. When the housing cracks, it binds forward into the blower wheel making a loud "rumble" noise and vibration. If you open the door and manually turn the drum and you hear a rubbing noise and feel alot of resistance, then you have a cracked blower housing and need to replace it. It is not an easy job to replace, so if your not familiar with dryers, you should have a technician replace it. Let me know if you have any further questions. shane

This sounds like a typical blower malfunction.
The links below, provided by www.repairclinic.com, will show you how to locate the blower and disassemble the dryer to replace the blower.
Some special tools may be required.

If you remove the front cover and access the blower fan and see if it is still tight on the shaft. if it isn't it makes a rumble sound when started due to vibrating and after a while it makes more noise as it goes. Now I removed the fan and placed a shim in the flat area and matched the flat area of the shaft and replace it back on the shaft and it should solve it.

Check the motor coil..
