Understanding the Problem
What this part is and what it fixes: The DC47-00019A is the heating element (or part of the heating assembly) used in many Samsung electric dryers. When the element fails the dryer will tumble but produce little or no heat, causing long dry times or no drying at all. Step-by-step diagnostics and repair (practical how-to): 1) Confirm the symptom: dryer runs, drum tumbles, but clothes stay wet or drying times are very long; you may also notice a burnt smell or visible damage in the heater area. 2) Safety first: unplug the dryer or turn OFF the breaker for the dryer circuit (240VAC). Work only on a dead appliance. 3) Verify incoming power (optional, expert): with the dryer plugged back in and a helper starting the dryer, measure across the two hot legs at the terminal block — you should see ~240 VAC. If you only have 120 VAC between either hot and neutral, the dryer won’t heat; troubleshoot house circuit before replacing parts. 4) Access the heating element: most models require removing the rear or front access panel and the heater housing cover. Refer to your model service manual or remove the back panel to reach the element assembly. 5) Visual inspection: look for broken heating coils, burned/melted insulation, scorch marks, or pieces of melted coil. If visible damage exists, the element is bad. 6) Continuity test (element): with power off and element disconnected, use a multimeter set to ohms. Measure between the two element terminals — a working element shows low resistance (usually in the single digits to a few dozen ohms depending on model). Infinite/OL = open element (replace DC47-00019A). 7) Ground short test (element): measure between each element terminal and the metal housing/chassis. You should see no continuity (OL). Any continuity to ground means the element is shorted to the housing and must be replaced. 8) Check the thermal fuse and thermostats: many Samsung dryers use a thermal fuse (commonly referenced as DC96-00887A in service videos) on the blower housing and several thermostats/high-limit cutouts. An open thermal fuse or thermostat will also cause no heat. Test for continuity; an open thermal fuse = replace it. 9) If element and fuses are good but no heat: confirm the dryer’s controls/relay supply 240VAC to the element during a heat cycle (requires measuring voltage at the element terminal with dryer running). No voltage indicates a bad timer/control board, failed relay, wiring fault, or broken cycling thermostat. 10) Replace the heating element (if bad): a) Unplug dryer. Remove access panel to the heater housing. b) Photograph or label wire locations to ensure correct reconnection. c) Disconnect wires and remove mounting screws/clips that hold the DC47-00019A assembly. d) Pull out the old element and install the new DC47-00019A (or full heating assembly if replacing more parts). e) Reconnect wires, reattach housing and panels, restore power and test dryer on a timed cycle. Confirm heat production and that thermostats/thermal fuse do not blow immediately. Safety note: Always disconnect power before opening the dryer. Use insulated tools and a multimeter rated for the voltages you’re testing. Thermal fuses are one-time devices — if they’re open replace them rather than bypassing. If you’re not comfortable testing live voltages, consult a qualified appliance technician.
Common Symptoms
Dryer runs but produces little or no heat; very long drying times; burning smell or visible broken/burnt heating coils; occasional tripping of a breaker or blown thermal fuse.
Common Causes
- Open/broken heating coil inside the DC47-00019A element assembly
- Heating element shorted to the metal housing (grounded element)
- Blown thermal fuse or open high-limit thermostat upstream of the element
- No 240V supply to the element due to a bad control board, relay or wiring fault

Helpful Repair Tip
Quick confirm: with power off, remove the heater wiring and check continuity across the element terminals — open (OL) means replace; also test each terminal to the metal housing — any continuity to ground means the element is shorted.
Frequently Asked Questions
How can I tell if DC47-00019A is the part that needs replacing?
Test the element with a multimeter: disconnect power, remove the element wiring, and check continuity between the two element terminals (low ohms = intact; open = broken). Also test each terminal to the metal housing — any continuity indicates the element is shorted to ground. Visible breaks or burn marks on the coils are another clear sign.
Can I replace the DC47-00019A myself and how long will it take?
Yes — a competent DIYer can replace it. Typical time: 30–60 minutes depending on access and model. Steps: disconnect power, remove access panel, label and disconnect wires, remove mounting screws, swap the element, reconnect wires and panels, then test. If you’re unsure about live-voltage tests or don’t have the right tools, hire a qualified technician.
