Samsung Dryer Cool Down Cycle Not Working



Check the Drying mode/Moisture sensor

My Samsung dryer is a year and a half old and it has also stopped heating. I've confirmed there are no air flow obstructions and am not looking forward to calling the company to see what they'll do about it. So frustrating, an expensive appliance shouldn't stop working at 18 months. Call us today with you model number and we will make sure you get the right part888-655-8569In most cases we can get you the part the next day if ordered bef. The electric dryer is heating fine except on the Perma press cycle. I’m getting the he code before it’s through the entire cycle, when I open the door it’s really hot so I do believe it’s not getting to the cooling down cycle.

Although not common, if the dryer is slow check the lint filter. The lint filter can get clogged with fabric softener and not allow enough air to pass through. Clean the filter of any residue that might prevent proper air flow. Replace the electronic control board if it's receiving voltage but isn't transmitting it to the dryer components, causing the dryer to not work. The dryer may start but then stop in the middle of the cycle if internal control board components don't detect sensor signals accurately.


Timer on dryer not working If your dryer does NOT start right back up, then it might be the motor overheating.
If your dryer starts right back up, then it's not likely an overheating issue as the relay would not allow the motor to start back up.
This could be a few issues:
1) Some dryers have a mode based on dryness like 'less dry' or 'more dry' and uses mist/moisture sensor to determine when to shut off. When you start the dryer, it may state the default time like 50 min. But if it is a smaller load, it may shut off in 10, 20 min or less than the noted time on the display.
To test this, try a TIME DRY mode and set it to the exact time you need and time it on another device like your phone. If the time aligns, then you're probably good and maybe it was set to dryness mode before.
On a DRYNESS mode, set it and sync with another timer to the time the dryer states on the display (example: 50 minutes). When the dryer shuts off, compare the times and check the clothes. If the clothes are dry, it is likely that your dryer is just running in DRYNESS mode and sensing your clothes are dry.
note: I have a Frigadaire Affinity and the button for the mode has less dry, normal, more dry options. If you set it to normal, it should run the full 50 minutes. On the other options, it will stop when the clothes are dry.
2) A bad mother board - this could be a $200+ repair/replacement. Bad boards create all types of strange issues.

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.

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.

Samsung Dryer Cool Down Cycle Not Working Remotely

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.

Samsung Dryer Stays In Cool Down Mode

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