LG DLG3421W Quiet Dryer Repair

LG dryer

Most common issues on this model

  1. New noise on a dryer designed for quiet operation
  2. AI Sensor Dry cycle ending
  3. Burner igniter and gas valve
  4. ThinQ app connection

The DLG3421W is a current LG front load gas dryer with a 7.4 cu. ft. ultra large capacity. It is designed for quiet operation and adds AI Sensor Dry, FlowSense duct clogging and lint filter indicators, and ThinQ app support with ThinQ UP features.

On a quiet dryer, a new thump, squeal or rattle is easy to notice, and it usually comes from the rollers, the belt or the idler. We also check the blower area for a lint clump. When heat is the problem, we test the igniter and gas valve coils after confirming the shutoff.

App and cycle questions begin with the network and the airflow. We read the model and serial from the label before ordering parts and give you the written price first.

DLG3421WDLG3421W questions
My quiet dryer got loud. What changed?

Worn rollers, a belt or the idler are the usual causes, and a lint clump in the blower area can add rattling. We find the source with the drum off its supports.

What is AI Sensor Dry?

It selects dry settings based on what it senses in the load. If clothes come out damp, we clean the sensor contacts, check airflow and then test the board.

Does ThinQ UP matter for repairs?

Not for the heat and drive parts. It matters if features will not download, in which case we check the network connection and the dryer settings.
