Samsung Dryer Error Code Hr — What It Means & How to Fix It

What Does This Error Mean?

The Hr error means your Samsung dryer has detected dangerously high heat inside the drum. The dryer shuts itself down as a safety measure to prevent a fire. The most common cause is a blocked dryer vent that traps heat and causes temperatures to spike.

Common Causes

A severely clogged dryer vent hose or exterior vent cap is trapping heat
The lint trap has not been cleaned and is heavily blocked
The high-limit thermostat has failed and is allowing temperatures to rise too high
The heating element is stuck in the 'on' position and not cycling off
The dryer is installed in a very small enclosed space with no air circulation

How to Fix It

Let the dryer cool down completely before doing anything — at least 30 minutes.

The dryer has just overheated. Do not restart it immediately.
Clean the lint trap thoroughly.

Remove all visible lint. Rinse the lint screen under running water if it looks coated — fabric softener residue can clog the mesh.
Disconnect and clean the entire dryer vent hose from the back of the dryer to the wall.

Use a dryer vent cleaning brush (available at hardware stores for $15–$25). Remove all lint from the hose.
Go outside and check the vent cap on the exterior wall.

Make sure the flap opens freely and is not packed with lint, debris, or blocked by a pest nest.
Plug the dryer back in, run a short cycle, and monitor for the Hr error.

If the error returns immediately after cleaning the vent, the thermostat or heating element needs professional inspection.

When to Call a Professional

If vent cleaning does not resolve the Hr error, the high-limit thermostat or heating element may need replacement. These repairs require disassembly of the dryer cabinet. A technician can diagnose and repair for $150–$350. Do not continue using the dryer until the issue is resolved — overheating is a fire risk.

Frequently Asked Questions

Is the Hr error dangerous?

Yes — overheating is one of the leading causes of dryer fires. If your dryer shows Hr, stop using it until the cause is fixed. A clogged vent is the most common reason and is easy to clean yourself. But if the thermostat or heating element is faulty, a technician is needed.

How often should I clean my dryer vent?

At minimum, clean the full vent hose once a year. If you do many loads per week, clean it every 6 months. The lint trap should be cleaned after every single load. Regular cleaning prevents the Hr error and reduces fire risk.

My dryer vent looks clear but I still get the Hr error. What now?

If the vent is clean, the problem is likely the high-limit thermostat. This part cuts power to the heating element when temps get too high. If it's stuck in the wrong position, the dryer overheats. A technician can test and replace it for $100–$200.
