Samsung dryer runs but does not heat

Samsung dryer runs but does not heat: airflow, cycle choice and household power or gas supply should be proved before heater or valve service. Scoped to DVE45T6000*.

If the Samsung DVE45T6000 tumbles but does not heat, the manual's first suspects are not parts. Eco Dry is on by default for Normal and Time Dry and begins with an air-dry stage that uses no heat, so the drum feels cool for a while at the start. Other checks are the breaker or fuse, a clogged lint filter or duct, a cycle that does not use heat, and the cool-down phase at the end of a cycle. Turn Eco Dry off and run Time Dry on High before deciding anything is broken.

Differential

Likely causes of “Samsung dryer runs but does not heat”, and how to tell them apart

  1. 1

    Eco Dry is on and the cycle starts with unheated air

    What separates it The drum is cool for the first stretch and the cycle time is longer

    How to confirm Turn Eco Dry off for Normal or Time Dry and start again

  2. 2

    A tripped breaker or blown fuse on one leg

    What separates it The drum turns but the exhaust stays cool for the whole cycle

    How to confirm Reset the breaker once or replace a fuse with the same rating

  3. 3

    A clogged lint filter or restricted exhaust that trips the heat off

    What separates it Clothes are warm and damp and HC or a check code shows

    How to confirm Clean the lint filter and run the Vent Blockage Test

  4. 4

    A cycle that does not use heat, or the cool-down phase

    What separates it Air Fluff was selected, or the cycle is near its end

    How to confirm Check the selected cycle in the cycle chart and choose a heated cycle

Before you touch a setting

Record this first — changing settings destroys the evidence

  • Whether the dryer is electric or gas from the label inside the door
  • Whether Eco Dry is lit and which cycle was used
  • Whether HC, tC, tC5 or a check code appeared

  1. Turn Eco Dry off

    Reversible

    Samsung says that when Eco Dry is on for NORMAL or TIME DRY, the dryer performs an air dry process at the start to reduce energy use, so you may feel no heat, which is normal. Press Eco Dry to turn it off and start again.

  2. Check the breaker or fuse

    Reversible

    Look at the panel for a tripped breaker on the dryer circuit. Reset it once. If it trips again the manual says nothing further, but an overload needs an electrician.

  3. Clean the lint filter and duct

    Reversible

    Take out the lint filter and clean it. The manual says to clean the lint filter and exhaust duct, use 4 inch rigid metal duct and make sure the outside hood opens and closes freely.

  4. Check the selected cycle

    Reversible

    Some cycles do not require heat. Choose Normal, Heavy Duty or Time Dry with the Temp. button on High, then feel the exhaust after a few minutes.

  5. Read the code

    Reversible

    HC means the dryer detected abnormal temperature in the drum, tC and tC5 mean a thermistor reading is very low or high, and Samsung's fix for all of them starts with the lint filter and the vent.

Model-specific

What is true of this model and not of its siblings

Eco Dry
Eco Dry works with NORMAL and TIME DRY. Drying can take up to three times as long depending on temperature and load, and the function is enabled by default. Samsung's troubleshooting table tells you to switch it off if the dryer seems not to heat.

Stop boundary

When this stops being a self-service repair

  • !If you smell gas at any point, leave and call the gas supplier from outside
  • !If the breaker is fine, Eco Dry is off, the filter and vent are clean and the exhaust is still cool, contact a Samsung service center

Exact questions

Common questions

Why is the drum cool at the start of Normal?+

Eco Dry is enabled by default and starts with an air dry process that uses no heat. Turn it off for a fully heated cycle.

What do tC and tC5 mean?+

Thermistor 1 or 2 resistance is very low or high. Check for a clogged lint screen and a restricted vent, then call service if the code stays.

Could low voltage cause this?+

Samsung notes that low voltage may stop the dryer drying properly and asks you to confirm 240 V between L1 and L2.

Is the end of the cycle cool?+

Yes. The final part of the cycle runs without heat, so warm clothes that cool at the end are normal.
