Error Code Explained

What Does the Samsung Hr Error Code Mean?

The Hr error code on a Samsung dryer signals that the drum temperature has exceeded the maximum safe operating limit. Samsung dryers monitor drum temperature via a thermistor and a thermal limiter. When the temperature exceeds the high-limit threshold, the control board displays Hr and shuts off the heating circuit to prevent damage or fire.

Hr is closely related to Fd (airflow restriction) — a blocked exhaust vent is the most common trigger. With restricted airflow, heat builds up in the drum instead of being carried out through the duct.

Root Causes

Common Causes of the Samsung Hr Error Code

1

Blocked Exhaust Duct

Lint in the exhaust duct traps heat inside the drum, causing temperature to spike past the high-limit threshold.
2

Blown Thermal Fuse

If the temperature spike was severe enough, the thermal fuse on the heating assembly may have blown. A blown thermal fuse disables heating permanently until replaced.
3

Failed High-Limit Thermostat

The high-limit thermostat that cuts power to the heater at the temperature threshold has failed open, allowing continuous heating past safe limits.
4

Cycling Thermostat Failure

The cycling thermostat failed closed, preventing the heater from cycling off between temperature peaks and allowing the drum to overheat.

Step-by-Step Guide

How to Troubleshoot the Hr Error Code

⚠️

Safety First: Always disconnect the Dryer from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Clean the exhaust duct immediately

Disconnect the dryer and clean the full duct run. A completely blocked duct is the root cause in most Hr events. Do not run the dryer again until the duct is clear.
2

Test the thermal fuse

After an overtemperature event, test the thermal fuse for continuity with a multimeter. The fuse is a one-shot device — if it shows no continuity, it must be replaced even if the dryer appears to run.

When to Call a Samsung Technician

⚠ Stop DIY if any of these apply

If the duct is clean and Hr still appears, or if the dryer runs but produces no heat after clearing Hr, the thermal fuse, cycling thermostat, or high-limit thermostat requires replacement. These are moderate repairs requiring access to the heating assembly.

FAQ

Frequently Asked Questions — Samsung Hr

Not necessarily — Hr is triggered when the temperature threshold is first exceeded, which blows the thermal fuse as a safety backup. If the fuse blows, the dryer will subsequently run without heat. Always test the fuse after an Hr event.
A power reset may clear the Hr code from the display, but if the underlying cause (blocked duct or failed thermostat) is not resolved, Hr will return — and the thermal fuse may blow permanently.
