🔨 Pro Tip from Drew

When troubleshooting no-ignition on the DVG45BB6900H, don’t overlook the radiant sensor (Samsung part DC47-00019A). Many techs replace the igniter first and miss this. A tricky aspect of this model is that the sensor can test fine at room temperature but fail under heat, so I recommend replacing both the igniter and the sensor together to avoid any repeat visits.

Common Symptoms & Causes

If your Samsung DVG45BB6900H isn’t igniting, you might notice one or more of the following symptoms before or during a cycle:

The dryer drum spins, but no heat is produced throughout the cycle.
You hear a faint clicking sound, but the burner never lights.
The dryer displays error code HE or HC, indicating a heating failure.
Clothes remain cold and damp after a full drying cycle.

These signs typically point to a failed igniter, a faulty gas valve coil, or a worn thermal fuse interrupting the ignition circuit.

Safety First

Unplug the dryer from the power outlet before starting any repair — never work on a live appliance.
Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
Take photos with your phone before disconnecting any wiring harnesses or connectors.
Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

First, unplug the dryer and shut off the gas supply valve at the wall. Wait a few minutes and check for any lingering gas odor before proceeding — it’s crucial that no gas is present before opening the cabinet. If you smell gas, leave the area immediately and contact your gas utility. Open windows and doors to ventilate the laundry room as you prepare your tools.

Step 2

Remove the rear panel by backing out the six ¼-inch hex screws around its perimeter. Set the panel aside to expose the gas burner assembly mounted at the bottom rear of the cabinet. This area contains all the ignition components — igniter, flame sensor, and gas valve — so a visual inspection can often reveal burn marks, cracked igniters, or corroded terminals.

Step 3

Next, test the glow-bar igniter by disconnecting its harness connector and setting your multimeter to Rx1 (resistance). A healthy igniter will read between 50–400Ω. If you see a reading above 600Ω or an open (OL) circuit, the element is too weak to reach ignition temperature or has failed entirely and needs replacement. The igniter is the most common cause of no-ignition issues on this model, as it also acts as a current-sensing switch, signaling the gas valve to open. If it glows dimly or not at all, gas will never flow. Be careful handling the glow bar; don’t touch the ceramic element, as skin oils can create hot spots that shorten its lifespan.

Step 4

Disconnect the flame sensor harness and test the bi-metal sensor on Rx1 continuity. At room temperature, you should hear a beep or see near-zero resistance, confirming the contacts are closed and the circuit is complete. An open reading at room temperature indicates the sensor has failed in the open position, preventing the control board from ever allowing a heat cycle to complete, so it should be replaced. This sensor is a safety device that shuts off gas if the dryer overheats, so never bypass it.

Step 5

With the gas supply valve still closed, disconnect the wiring leads from the two solenoid coil caps on the gas valve body and test each coil individually on Rx1. The primary coil should read around 1,300Ω, while the secondary coil should fall between 90–600Ω. An open reading on either coil means the solenoid cannot pull the valve plunger open, preventing gas flow even if the igniter glows. You can replace the solenoid coil kit instead of the entire valve, which saves you significant money. Label or photograph the wiring positions before removing any leads to ensure correct reassembly.

Step 6

Reassemble the rear panel, then slowly reopen the gas supply valve. Listen for any hissing sounds that could indicate a disturbed fitting; if you hear one, shut the valve immediately and check your connections. Plug the dryer back in and run a heated cycle, watching through the burner opening if possible. The igniter should glow bright orange within about 30–45 seconds, and the gas should ignite within 90 seconds of the cycle starting. If the igniter glows but gas doesn’t light, the issue is likely with the gas valve solenoids. If it doesn’t glow at all, recheck your igniter resistance and harness connections.

When to Call a Professional

If the issue persists after you’ve completed all the steps above, there may be a problem with the main control board, a defective heating element, or wiring that requires specialized diagnostic equipment. At that point, it’s best to contact a licensed appliance technician. And remember, on gas dryers, any work on the gas valve or supply line should only be handled by a licensed gas fitter in most jurisdictions.

How Much Does This Repair Cost?

DIY parts for fixing no ignition on a Samsung DVG45BB6900H typically cost between $20 and $80, depending on whether you need an igniter, valve coils, or a control board. A professional service call for the same repair usually runs $150 to $300, including labor. Tackling this repair yourself can save you $100 or more.

Frequently Asked Questions

Why is my Samsung DVG45BB6900H not igniting even though the gas supply is on?

The most common culprit is a faulty igniter. It can weaken over time and may no longer generate enough heat to light the burner. Test the igniter with a multimeter and replace it if it shows no continuity.

How do I know if the gas valve or the igniter is causing the no-ignition problem?

If the igniter glows but the burner never lights, the gas valve coils are likely the issue and need replacing. An igniter that never glows at all usually indicates a failed igniter or a broken igniter circuit.

Is it safe to repair the ignition system on my Samsung gas dryer myself?

Yes, but remember to unplug the dryer and shut off the gas supply before starting any repair. If you smell gas at any point during the process, stop immediately and contact a licensed technician.

The Igniter That Fixes Most No-Ignition Calls on This Samsung Model

On the DVG45BB6900H, a dead igniter is responsible for the majority of no-ignition complaints I see. If your dryer’s burner won’t light but you’re hearing the gas valve click, the igniter is almost always your first stop—and honestly, it’s the easiest of the common culprits to swap out yourself.

What works

Igniter glow is immediate and visible once you fire up the dryer after install—you’ll see that telltale orange glow right away, so diagnosis is instant.
The mounting bracket on this model is straightforward; two screws and a connector plug mean you’re in and out in under 10 minutes.
OEM-spec fit means no fumbling with adapters or worrying about clearance near the burner box.

What doesn’t

If your no-ignition symptom is actually a flame sensor failure, swapping the igniter first will leave you chasing your tail—the burner will light but shut off within seconds.
You’ll need to let the dryer cool for at least 15 minutes before touching the old igniter, or you’ll burn yourself; the element stays hot long after the last cycle.

I’ve had homeowners order this igniter only to find out the real problem was a faulty flame sensor—so always do a quick click-and-spark test at the burner before pulling parts. That said, if you hear the gas valve solenoid click but see no spark or glow, this is your part. Grab the igniter and test it as soon as it arrives.
