Symptom
Samsung dryer not heating
Different from a dryer that runs warm and does not dry. Here there is no heat at all, and the list is short: on an electric machine the element, its thermostats or the supply; on a gas machine the burner sequence; on a heat-pump machine the compressor circuit.

Four ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
Half the supply missing
A double breaker with one side tripped, or a loose connection. Tumbles fine, no heat.
Dryer heating element replacement from $175 -
The heating element
Or its thermostats and the thermal cut-out, which are a circuit and are tested together.
Dryer heating element replacement from $175 -
The burner sequence on gas
Samsung's HC2. Igniter, valve or flame sensor.
Gas dryer igniter replacement from $185 -
A blown thermal cut-out
Which is a symptom of a blocked duct rather than a cause in itself.

01
Confirm it really is cold, not just cool
Feel the exhaust outside. Slightly warm is a different page.
-
02
On electric, have the breaker and the outlet checked
Both legs. This is measured by somebody qualified, not guessed at.
-
03
On gas, listen for the igniter
It glows and then the burner should light with a soft whump.
-
04
Check the duct anyway
A blocked duct takes out thermal cut-outs, so it is often behind an element failure.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.
If there is no code at all
The data plate is inside the cabinet, upper left wall or behind the grille. All models

About Samsung dryer not heating
Check the obvious supply case first
On an electric dryer, a machine that tumbles perfectly and produces no heat at all is very often half its supply — one leg of a 240-volt circuit gone at a breaker or a connection. The motor runs on one leg and the element needs both, which is exactly this symptom. It is an electrician's check, and it is worth doing before an element is bought.
What it usually means, by the kind of Samsung appliance
Samsung sells one appliance in several forms, and the same behavior points at different things on each of them. A built-in side-by-side and an integrated column are not the same service situation, and a dual-fuel range and an induction range fail in different halves.
- Vented electric — Element, thermostats, thermal cut-out and the relay. Half of a 240-volt supply missing gives a dryer that tumbles cold.
- Vented gas — Samsung's HC2. Igniter glows, valve opens, flame sensor confirms — and any one of the three stops it.
- Heat pump — No element at all. A machine that tumbles cold here is the refrigeration circuit and it is a different conversation.
Why the duct is on a heating page
The thermal cut-out in a dryer exists to stop it overheating when air cannot move. When it does its job, the dryer tumbles and does not heat — which looks exactly like a failed element. Replacing the cut-out without clearing the duct gets you a dryer that works for a week. Every heating repair on this site includes checking the airflow for that reason.
The gas sequence
Three parts have to work in order: an igniter that glows red, a gas valve that opens, and a flame sensor that confirms the flame so the valve stays open. Watching one start attempt tells a technician which of the three it is, which is why we ask you not to keep cycling it before the visit.

Before you book
Questions about Samsung dryer not heating
It heats for a while and then goes cold mid-cycle.
That is the classic thermal cut-out or cycling thermostat picture, and it points hard at airflow. Have the duct done before anything is replaced.
Can I use it while I wait?
On an electric machine that tumbles cold, yes, though it will not dry. On a gas machine, or if there is any smell of gas, no — call and stop using it.
