Samsung Ignitor DC47-00022A — What Part Fixes This Problem?

Understanding the Problem

What this part is and why it matters: The DC47-00022A is a glow (hot surface) ignitor used on Samsung gas ovens/ranges. It heats until it glows hot enough to open the gas safety valve and ignite the burner. When the ignitor fails (open, weak, cracked, or draws insufficient current) the oven will not light or will take a long time to light, causing safety shutoff or no heat. Step-by-step diagnostics and repair: 1) Safety first: Turn off the oven at the wall circuit (unplug) and shut off the gas supply to the appliance before you start. Allow the oven to cool completely. 2) Observe behavior: Try to start the oven with the power and gas on (if you performed an initial test before disconnection). Note if the ignitor glows dim/orange/red and gas never flows, or if it doesn't glow at all. 3) Visual inspection: Remove the oven bottom/broiler drawer or access panel to see the ignitor assembly. Look for cracks, broken glass-like surface, burn marks, or loose/corroded wiring/connectors. 4) Electrical test (basic continuity): With power off, disconnect the ignitor wires and check for continuity with a multimeter. Many failed ignitors are open (no continuity). If open, replacement is required. 5) Glow/current test (functional): With the oven powered and gas on (only if you are comfortable and safe), set to bake and watch the ignitor. It should start glowing bright orange within 20–30 seconds and the gas valve should open. If it glows but the oven doesn’t light or it never gets very bright, the ignitor is weak and should be replaced. (If unsure, hire a tech — working with live gas is hazardous.) 6) Check wiring & gas valve: If ignitor tests good, inspect wiring and the safety gas valve. A working ignitor that draws the correct current should open the valve; intermittent wiring or a bad valve can also cause no ignition. Replacement steps (typical for many Samsung ranges): 1) Unplug the range and turn off the gas supply at the shutoff valve. 2) Remove oven racks and the oven bottom/broiler drawer to access the ignitor. 3) Locate the ignitor mounted to the burner/shroud. Remove the mounting screws securing the ignitor and carefully pull it forward. Support the ignitor — the ceramic/glass can be fragile. 4) Disconnect the wire connector at the ignitor. If connectors are corroded, cut and replace or use a new harness. 5) Install the new DC47-00022A ignitor: connect the wire harness (ensure tight, secure connections), position the ignitor in the same orientation and secure with the original screws. Do not overtighten — the ignitor is fragile. 6) Reassemble oven bottom/drawer and racks. Turn on gas and power. 7) Test: Set oven to bake and observe glow and ignition. It should glow bright and the burner should light within 20–30 seconds. Check for proper operation through a full cycle. 8) Final safety check: Smell for gas and check for leaks at any fittings you disturbed. If you suspect a leak, shut off gas and call a professional. Safety note: If you are not comfortable working with live gas or mains voltage, or if you detect a gas leak, stop and call a qualified appliance technician. Incorrect installation can create a fire or explosion hazard.

Common Symptoms

Oven won’t light, oven takes very long to ignite, burner lights intermittently, oven lights only when you manually light it, or no glow from the ignitor.

Common Causes

• Failed/open ignitor filament (ignitor cracked or burned out)
• Weak/glowing but insufficient current draw ignitor (old/weak ignitor)
• Loose/corroded wiring or bad ignitor harness or faulty gas safety valve
