Samsung Dryer Cool Down Cycle Not Working

When clothes are nearly dry, they fail to complete this circuit and the timer begins to run until the end of the cycle. If these sensors are defective or become coated with fabric softener, then the dryer will shut off before the clothes can dry. How to clean and test a dryer’s moisture sensor: Open your dryer door and locate your moisture. Dryer Won't Heat. That cooling light will normally stay on constantly during the cycle. It will begin blinking at the end of the cycle when the cycle goes into the cool down. If that light begins blinking shortly after starting the dryer in an automatic moisture sensing cycle then you could have a problem with the moisture sensing circuit.

Circuit Description and Operation

Sensor Dry Mode automatically measures the moisture in the load and shuts the dryer off when the proper level of dryness is reached. This sensor dry should not be confused with a temperature sensor, the sensor bars measure moisture and the temperature sensor “thermistor” measures temperature. Sensor dry uses nothing more than two metal bars inside the edge of the drum. These bars do not go bad unless they are physically damaged however it is always a good practice to clean them whenever servicing using some rubbing alcohol, especially when the unit gets older. Never use sand paper or other abrasive methods.

At the start of the cycle an estimated time will be displayed as the Main PCB monitors the sensor circuit for 3 minute after the 3 minutes the estimated time can increase decrease, stay the same or advance to off based upon the moisture detected. The unit will do this assessment multiple times during the auto cycle and can adjust the estimated time as needed.

Diagnostic Procedure:

The sensor dry bars can be checked easily by

placing a coin across both bars and checking for

continuity. Spongebob squarepants all seasons torrent download full.

Being more specific the resistance values are listed

below

Dry Clothes = Infinity

Wet Clothes = ~190 ohms ±10%

The sensor bars can be also tested in diagnostic mode. Place a slightly damp cloth in the dryer, start a normal cycle then press the Temp + Signal buttons for 3 seconds. When there are wet items being dried, data will add up (from 0 to 1200 and repeating) as the wet clothes touch the sensor bars. If the sensor bar value does not increase as wet items contact it the sensor is defective.

NOTE: Select any Auto cycle without clothes hit start unit should run for 3-5 minutes and shut off.

Usage and Customer Education:

Sensor Dry Mode automatically measures the moisture in the load and shuts the dryer off when the proper level of dryness is reached.

At the start of the cycle an estimated time will be displayed as the Main PCB monitors the sensor circuit for 3 minutes. After the 3 minutes the estimated time can increase, decrease, stay the same or advance to off based upon the moisture detected. The unit will sample moisture level multiple times during the auto cycle and can adjust the estimated time as needed.

The length of the dry time will be proportional to the size of the load as well as the moisture in the clothes. However there are several factors that will effect dry time. These can be installation issues such as improper venting or a clogged lint filter. Another reason for clothes not being fully dried is the fabric itself. For example, towels or jeans are very thick and can contain some moisture even though the outward edge is dry. For best results always wash like items such as towels with towels jeans with jeans etc. It is important that loads are large enough to make adequate contact with sensing bars for feature to work properly. The customer complaint for undersized loads would be “clothes not dry at end of cycle”. If consumer has the need to wash and dry just a few articles of clothing recommend using time dry for those loads.

NOTE: Always remember the time being displayed is an estimated time and can increase, decrease, stay the same or advance to off anytime during the cycle.

NOTE: Wrinkle Prevent Feature will extend cycle for 90 minutes. Drum will tumble with no heat and lights in control panel will oscillate.

Wrinkle Prevent is often overlooked as possible cause for long dry times or dryer never shuts off.
