How to Replace DG94-00520A Oven Burner Igniter on Samsung Gas Range — Step-by-Step

Your Samsung oven stopped heating, but you can hear the gas flowing and see the igniter glowing orange. That's the classic sign of a failing burner igniter — it's drawing current but not getting hot enough to ignite the gas. On models like the NX58H5600SS or NX58F5500SS, this DG94-00520A igniter typically lasts 5-7 years before needing replacement.

The good news? This repair takes about 30 minutes and doesn't require specialized tools. You'll save $200-300 in service call fees by doing it yourself.

What You Need Before Starting

• Phillips screwdriver
• 1/4" nut driver or socket wrench
• Flashlight or work light
• Work gloves (optional but recommended)

Repair Time: 25-35 minutes
Difficulty: Easy — Perfect for first-time DIYers

Safety First

Gas appliances demand respect. Turn off the gas supply valve behind the range before you start — it's usually a yellow or red valve on the floor or wall. Unplug the range or flip the circuit breaker to kill electrical power. Even though you're only working with the igniter, eliminating both hazards is the smart move. Let the oven cool completely if you've recently used it.

Step 1: Access the Igniter Location

Open the oven door fully and remove the oven racks — they'll just be in your way. Look at the bottom of the oven cavity. You'll see either a metal panel covering the burner assembly or direct access to it depending on your model. On the NX58H9500WS and similar models, there's a single metal panel held by four screws. Remove those screws and lift the panel out carefully.

Step 2: Locate and Document the Wiring

Shine your flashlight into the burner area. The igniter sits at the back or side of the burner tube — it's a ceramic piece with two wires attached. Before disconnecting anything, snap a quick photo with your phone. You're looking at a simple two-wire connection, but that photo will save you five minutes of confusion during reassembly.

Common Issue: Contaminated Igniter Surface

While you're here, inspect the old igniter. Food spills and grease buildup reduce its effectiveness over time. Even if the igniter glows, contamination prevents it from reaching ignition temperature. That's why your oven runs but won't heat — the gas safety valve never opens because the igniter can't draw enough current.

Step 3: Remove the Old Igniter

Disconnect the two wires by gently pulling apart the spade connectors. Don't yank — if they're stuck from heat cycling, wiggle them side to side while pulling. The igniter mounts with two screws through a metal bracket. Remove those screws with your nut driver. The old igniter will come free along with its bracket. Handle it gently even though it's toast — that ceramic material is brittle and can create sharp fragments.

Step 4: Install the New DG94-00520A Igniter

Position the new igniter exactly where the old one sat. The ceramic portion should align parallel to the burner tube for optimal gas ignition. Thread the mounting screws through the bracket and tighten them snug — not gorilla-tight, just firm. Over-torquing can crack the ceramic base. Connect the two wires to the spade terminals on the igniter. They only fit one way, but double-check against your photo to be sure.

Step 5: Reassemble and Test

Replace the bottom panel and secure it with the screws you removed earlier. Slide the oven racks back in. Now for the moment of truth: turn the gas supply back on and restore power. Set the oven to 350°F and listen. Within 60-90 seconds, you should hear the igniter click and the gas whoosh as it lights. The igniter will glow bright white or orange for about 30-40 seconds before the burner flames up.

Testing After Installation

Let the oven run through one complete heating cycle. It should reach 350°F within 10-12 minutes — that's normal preheat time. Watch through the door window during the first ignition to confirm the flame spreads evenly across the burner. If you smell gas or the igniter glows but won't light after two minutes, shut everything off immediately and recheck your connections. A properly installed igniter should work flawlessly on the first try.

Frequently Asked Questions

Why does my igniter glow but the oven won't heat?

The igniter draws current through the gas valve safety circuit. When it's weak or contaminated, it glows but doesn't pull enough amperage to open the valve. The valve needs 3.2-3.6 amps to open — a failing igniter might only draw 2.8 amps. Your oven sees the glow and thinks everything's fine, but the gas never flows. That's why replacing the igniter fixes the "little to no heat when baking" symptom immediately.

Will this igniter fit my Samsung model number?

The DG94-00520A works across dozens of Samsung gas ranges made between 2013-2020, including the NX58H5650WS, NX58J7750SS, NX58K9850SS, and NX58M6630SS series. Check the compatible models list on the product page — if your full model number (including the letters after the slash) appears there, you're good to go. This igniter replaces Samsung part numbers AP5577941, PS4241428, and several others.

How long does a Samsung oven igniter typically last?

Expect 5-7 years with normal use, but heavy bakers might see failure sooner. Each heating cycle stresses the igniter as it heats from room temperature to 2500°F in seconds, then cools back down. Food spills accelerate wear because they create hot spots on the ceramic surface. If your range is approaching the 5-year mark and you're seeing slow preheat times or intermittent failures, the igniter's probably on its way out.
