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.
When I pull up to a house and see H01 on a Samsung dryer, I already know what I'm grabbing from the truck. Nine times out of ten it's a snapped heater coil or a blown thermal fuse. Ignore it and you've got an expensive laundry tumbler with zero heat. And it won't fix itself, so the longer you wait the bigger the pile of wet clothes gets.

What Does the H01 Code Mean?
Samsung heater coils sag and snap after a few years, honestly it's just what they do. H01 is the board saying it tried to send power to the heater but got nothing back. I replaced three of these last month alone, mostly on DVE45 models. Before you order parts though, go check your vent duct first. A clogged vent is usually what killed the last heater, and it'll kill the new one too if you don't deal with it.
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 flashing on the display right at cycle start, or sometimes about 5 minutes in after the control board checks the heater circuit
Drum spinning and motor running fine, but you open the door mid-cycle and the clothes feel exactly as cold as when you loaded them
A full 45-minute cycle completes like nothing's wrong, but everything comes out wet and cold. Zero heat the whole time.
The code clears when you reset power but comes right back within a few minutes of the next cycle starting
Can you reset a Samsung dryer to clear the H01 code?
Once you have swapped the failed element or fuse, a simple power cycle usually clears the error. Unplug the unit for a full minute to let the capacitors on the board discharge. When you restore power, the H01 should stay gone. If it returns immediately, you likely have a loose harness connection or a grounded element coil.

Frequently Asked Questions
What resistance should a Samsung dryer heating element read?
A healthy Samsung element sits right around 17 ohms at room temperature. Anything over 50 ohms means the coil has a partial break somewhere in the wire. A full OL reading means it's completely snapped. And if you see 0 ohms, the coil is shorted and touching the metal housing, which is a fire hazard. Both the OL and the 0 reading mean you need a new DC47-00019A heater assembly. Budget about $35-45 for the part online, and it's a pretty straightforward swap once you've got the back panel off.
Can a blown thermal fuse cause Samsung dryer H01 code?
Absolutely, and honestly I see this way more often than a broken element in houses with older flex vent hose. The thermal fuse is a one-time safety link in the heater circuit. When internal temps spike too high, it breaks the circuit permanently. Since H01 monitors the whole heater loop, a blown fuse looks identical to a broken element from the board's perspective. Always test that fuse before you toss the whole heater assembly. The fuse itself is about $8 versus $35-45 for the full element assembly, so it's worth the two minutes to check it first.
How do I access the heating element on a Samsung dryer?
Pull the dryer away from the wall and remove the entire back panel using a Phillips screwdriver or 5/16-inch nut driver. There are usually 8 to 10 screws running around the perimeter. The heater is tucked into a galvanized metal box at the bottom right of the cabinet. While you've got the back off, vacuum out all the loose lint that's collected in the bottom. Takes two extra minutes and cuts your chances of seeing this code again way down. Don't skip that step.
How long does it take to replace a Samsung dryer heating element?
First time doing it, budget about 90 minutes and don't rush. If you've done it before you're probably looking at 45 minutes to an hour. Back panel has 8-10 screws, disconnect the two wires off the element, unbolt the heater box from the frame (usually two screws), swap the assembly, reconnect everything, put the panel back. The part runs $35-45 online. Way cheaper than a service call. Just don't over-tighten the panel screws going back in or the thin sheet metal warps and you'll have gaps around the edge.
Why does the H01 code keep coming back after I replaced the heating element?
If it came back, one of three things is going on. Either your vent is still restricted and you're cooking the new element the exact same way you killed the last one, a wire connector is intermittently losing contact because the terminal is loose or corroded, or your replacement element has a ground fault. Go back and re-test the new element before anything else. Put one probe on the terminal and one on the housing. Should read OL. If it doesn't, the new part is either defective or the coil got bumped during installation and is now touching the housing. I've seen it happen.
