Samsung Dryer H01 Error Code: Heater Open Circuit

Quick Answer

Samsung dryer H01 error code means the heater circuit is open. The control board is not detecting any current flow through the heating element, which means the circuit is broken somewhere. Common causes are a physically broken heating element coil, a burned wire connector at the element terminals, or a blown thermal fuse located in the element assembly.

Samsung dryer H01 error code means the heater circuit is open. The control board is not detecting any current flow through the heating element, which means the circuit is broken somewhere. Common causes are a physically broken heating element coil, a burned wire connector at the element terminals, or a blown thermal fuse located in the element assembly. Test the heating element resistance with a multimeter. A good element reads 12-20 ohms. OL indicates a broken coil and the element must be replaced.

What Does the H01 Code Mean?

H01 means an open circuit in the heating element assembly. Test element resistance (spec: 12-20 ohms). Replace DC47-00019A if it reads OL.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Broken heating element coil (55%)40%
Blown thermal fuse in element assembly (25%)24%
Loose wiring harness connection (5%)22%
Burned or melted wire connector at element terminals (15%)14%

Symptoms You May Notice

  • H01 displayed on control panel
  • Dryer runs but produces no heat
  • Drum spins normally but clothes remain cold
  • H01 appears at cycle start or shortly after

Can you reset a Samsung dryer to clear the H01 code?

After replacing the failed component, unplug the dryer for 60 seconds, reconnect all wiring, and restore power. The H01 code clears automatically if the heater circuit is complete and reads within spec.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Unplug the dryer and allow it to cool for 15 minutes

Unplug the dryer and allow it to cool for 15 minutes. Inspect the wiring harness connectors at the heating element terminals. Reseat any connectors that appear loose.

2

Remove the rear panel to access the heating element assembly

3

Test for a ground fault

4

If the element tests good

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What resistance should a Samsung dryer heating element read?
A good Samsung dryer heating element reads 12-20 ohms. An OL reading means the element coil is broken and the element must be replaced. A reading near zero means the coil is shorted.
Can a blown thermal fuse cause Samsung dryer H01 code?
Yes. A blown thermal fuse in the heating element assembly creates an open circuit that the control board interprets as a heater fault and displays as H01. Test the thermal fuse for continuity before replacing the more expensive element.
How do I access the heating element on a Samsung dryer?
Remove the rear access panel after unplugging the dryer. The heating element assembly is in a housing at the lower rear of the drum area. Disconnect the wiring harness connections before removing the element bracket.
