When you have finished running a cycle in your Samsung Dryer and find that the load hasn't dried properly, even after cleaning the lint filter and vent lines, and also ensuring you have only put in a small load, it could mean that the heat exchanger needs to be cleaned.

It is recommended to clean the heat exchanger at least once a month. Some dryers even have an indicator that lights up to let you know when it needs cleaning. Please note that the indicator alert will continue to light up after each cycle, as it is recommended for you clean the heat exchanger after every cycle. A dirty heat exchanger will hinder the product's performance and should be cleaned regularly.

After a drying cycle, open the dryer door and the heat exchanger cover to maintain the dryer interior more hygienically. The heat exchanger will be wet right after a cycle so it is important to wait a few hours to let it completely dry before cleaning

Below are instructions on how to take out the heat exchanger and clean it.
