Understanding the Problem
What this part is: The DC47-00019A is the heating element (heating assembly) used in many Samsung electric dryers. It produces the heat that dries clothes. If the element is open, burned, or the housing is damaged, the dryer may run normally (drum turns) but produce little or no heat. Diagnostics & repair steps (step-by-step): 1) Safety first: Unplug the dryer and move it away from the wall so you can access the back or front. Turn off gas at the supply if you have a gas dryer (this part is for electric models). Allow the dryer to cool if recently used. 2) Inspect venting & lint: Before opening the dryer, remove the lint screen and check airflow. Disconnect the vent hose from the back and feel for airflow while running a short test cycle (unplug first, then reconnect power only when safe to test briefly) — restricted airflow can cause overheating and other failures. 3) Access the heating element: On many Samsung models the heater is accessed by removing the back panel or the lower front panel. Remove the screws holding the panel and carefully pull it off to expose the heating assembly and wiring. 4) Visual check: Inspect the heating coils/element for visible breaks, burn marks, or melted insulation. Also inspect the element housing and mounting for damage. 5) Test for continuity: Set a multimeter to the ohms (Ω) setting. With the dryer unplugged, test continuity across the heating element terminals — a good element typically shows a low resistance (tens of ohms depending on model). An open circuit (infinite/OL) means the element is bad. Also test related safety devices (thermal fuse, high-limit thermostat) for continuity — these commonly fail when element problems occur. 6) Inspect & test thermal fuse and thermostats: The thermal fuse (often mounted on the blower housing or heater housing) and high-limit thermostat(s) must have continuity. If the thermal fuse is blown (OL), replace it — replacing only the heating element without replacing a blown thermal fuse can leave the dryer non-heating. 7) Replace the heating element (if faulty): Remove and label/disconnect all wires from the element housing and any attached sensors or thermostats. Remove mounting screws/brackets and pull out the assembly. Install the new DC47-00019A assembly, secure with screws, reconnect all wires exactly as they were, and reattach the panel. 8) Replace any failed safety parts: If the thermal fuse or thermostat tested open, replace them too (they're inexpensive and commonly fail when a dryer overheats). 9) Reassemble & test: Reconnect vent hose, plug dryer back in, run a 10–15 minute empty cycle to confirm the dryer heats. Monitor for proper airflow and that it doesn’t overheat. Check for unusual smells or smoke — if present, stop and re-check wiring and connections. 10) Final steps: Reinstall the dryer in its location, ensure the vent is unobstructed, and run a full test with a towel load to verify drying performance. Safety note: Always disconnect power before opening the dryer. Heating element assemblies have sharp edges — wear gloves. If you are not comfortable working with electrical components, hire a qualified appliance technician.
Common Symptoms
Dryer drum tumbles but no heat or very low heat; long dry times; dryer initially heats then stops (could be thermostat/thermal fuse); visible broken or burned heating coil.
Common Causes
- Broken or burned heating coil inside the DC47-00019A assembly
- Blown thermal fuse or failed high-limit thermostat (safety devices)
- Restricted venting/airflow causing overheating and repeated safety cutouts or element damage

Helpful Repair Tip
Confirm the element is bad by measuring continuity across the heating element terminals with a multimeter; an open (infinite) reading means the element is failed. Also check the thermal fuse — a blown fuse is a very common cause of no heat.
Frequently Asked Questions
How long does it take to replace the DC47-00019A heating element?
For someone with basic tools and experience, removing the panel, swapping the heating element assembly, and reassembling typically takes 30–60 minutes. Allow extra time to diagnose related parts (thermal fuse, thermostats) if needed.
Can I replace the heating element myself or should I call a technician?
You can replace it yourself if you are comfortable with basic electrical safety and using a multimeter. Unplug the dryer, label wiring, and take photos before disconnecting. If you’re unsure, or if the dryer has complex wiring or repeated failures after replacement, call a qualified appliance technician.
