New Maytag dryer model mgdc400vw makes loud humming noise

have a service technician come and look the start/run capacitor for the motor
blowing a fuse then humming indicates a capacitator problem

People, the first words the poster said were that the dryer was "brand new". All of your suggestions assume the dryer had extensive use. This sounds like a factory defect issue!!!! My brand new Maytag Cabrio gas dryer is also making an obnoxious buzzing sound that seems to cycle on and off as the gas ignites. The buzzing sounds electronic not mechanical. What would buzz when the burner is active?

Hi,

The motor is going bad and this will make that loud humming when it is running...

replace the drive motor,its going bad.

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

Sounds like you need new drum rollers installed, when they get old they squeak,squeal, and make loud bumping noises.

the humming noise is most likely your motor. does it overheat or shut down on you? do you smell anykind of burning? Joe
