Understanding the Problem
The DC47-00019A is the heating element (or heating assembly) used in many Samsung electric dryers. When the element fails the dryer will run but produce little or no heat. This guide shows how to diagnose the element, check related safety parts, and replace the assembly. 1) Brief diagnosis overview: 1.1) Symptom check: dryer tumbles but doesn't heat, or takes very long to dry. 1.2) Quick checks: confirm proper power (240V for electric dryers), ensure the circuit breaker hasn't tripped, and verify the vent is not blocked. 2) Parts to check first (in this order): 2.1) Thermal fuse (common failure that mimics element failure). If the fuse is open, the dryer won't heat even if the element is good. 2.2) Heating element DC47-00019A (look for visible breaks, burn marks, or shorts to housing). 2.3) High-limit thermostat(s) and cycling thermostat(s). 2.4) Wiring and connectors for burned or loose connections. 3) How to test the heating element (step-by-step): 3.1) Safety first: unplug the dryer or turn off the breaker before starting any work. 3.2) Access the element: on many Samsung models remove the back panel (or front panel on some designs) to reach the heating assembly. 3.3) Visually inspect the element coils for breaks, sagging, or burning. 3.4) Set a multimeter to ohms (continuity). Disconnect the element wiring and measure resistance between the element terminals. A typical reading is a low resistance (single or double digit ohms). An open (OL) reading means the element is burned out. 3.5) Check for short to ground: measure between each element terminal and the metal housing; you should see no continuity. Continuity to housing = shorted element. 4) How to replace the DC47-00019A element (basic steps): 4.1) Unplug the dryer and shut off power. 4.2) Move the dryer away from the wall and remove the appropriate access panel (usually the back panel or front depending on model). 4.3) Take photos of wiring before disconnecting. Label wires if needed. 4.4) Disconnect the wiring from the element and remove mounting screws/clips, then slide the old element assembly out. 4.5) Install the new DC47-00019A element: position it, secure with screws, reconnect all wires using your photos/labels, and ensure gaskets/seals are seated correctly. 4.6) Reinstall panels, reconnect power, and run a short cycle to confirm heat. 5) Check related parts after replacement: 5.1) If the element was shorted, also inspect/replace the thermal fuse (e.g., DC96-00887A) and any thermostats as they can be damaged by failures. 5.2) Clean or replace the venting if it was restricted; restricted airflow contributes to overheating and element failure. Safety note: Always disconnect power before testing or working on the dryer. Heating elements and internal parts can retain heat and present shock hazards. If you are not comfortable working with electrical components, hire a qualified appliance technician.
Common Symptoms
Dryer tumbles but has no heat or very weak heat; loads take a very long time to dry; sometimes burning smell or tripped breaker if the element is shorting.
Common Causes
- Broken/burned heating coil inside the DC47-00019A assembly (open circuit).
- Heating element shorted to the metal housing (causes breaker trips or no heat).
- Blown thermal fuse or failed thermostat caused by overheating or restricted venting (results in no heat even if the element is good).

Helpful Repair Tip
Use a multimeter: continuity across the element terminals should show low resistance. If you get 'open' (OL) or continuity to the metal housing, replace the DC47-00019A.
Frequently Asked Questions
How do I know if it's the heating element or the thermal fuse?
Test both. Unplug the dryer, access the parts and use a multimeter. If the thermal fuse is open (no continuity) the dryer will not heat even if the element is good. If the thermal fuse has continuity but the element reads open (OL) or shorts to the housing, the element is bad. Always test element terminals for continuity and to the housing for shorts.
Can I replace the DC47-00019A myself and how long does it take?
Yes — a competent DIYer with basic tools and a multimeter can replace it. Typical time is 30–90 minutes depending on model and access (some models require removing the front or back panel). Always disconnect power, photograph wiring before removal, and verify you ordered the correct part for your exact model number.
