Samsung oven won’t light: check gas supply, igniter heat, burner cap seating, and power; replace a weak igniter if current is low.
If the cooktop fires but the cavity stays cold, use this guide to work safely, make fast checks, and confirm the likely failed part.
Quick Safety And Basics
If you smell gas, hear hissing, or a detector alarms, shut off the supply, ventilate, leave the area, and call your gas emergency line. Do not relight. When unsure, call a licensed tech.
Gas ovens still need electricity. Verify the plug, breaker, and outlet, and reset as needed. A dark or rebooting display points to a power issue.
Common Causes And Fast Checks
Start with simple observations, then test.
| Symptom | Likely Cause | What To Try |
|---|---|---|
| Igniter glows, no flame | Weak hot-surface bar | Measure amps; replace if low |
| No glow, no click | No power or control fault | Check outlet and breaker |
| Cooktop fine, oven silent | Open igniter circuit | Test continuity; inspect harness |
| Lights then goes out | Dirty ports or cap misaligned | Clean burner; reseat spreader |
| Only broil lights | Weak bake igniter | Replace bake assembly |
| Random lighting | Loose connectors | Power off; reseat plugs |
| No oven flame, others OK | Oven gas valve stuck | If amps in spec, replace valve |
Why The Glow-Bar Causes Most No-Light Cases
The glow bar and the oven safety valve sit in one series circuit. As the bar heats, current rises. When it reaches the valve’s threshold, the valve opens and the burner lights. A worn bar still glows orange but never draws enough current to open the valve.
Power And Gas Supply Checks
Open the manual shutoff fully. Straighten any kinked connector. If the range was moved, the handle may be left partway closed. Set it parallel with the pipe and retry. Samsung’s guide on burners that do not ignite covers supply checks you can apply to the oven, too.
On dual-fuel units, test the outlet with a lamp. Reset a tripped GFCI upstream. If the display flickers, solve power quality before chasing parts.
Taking Amp Readings On The Igniter
Clamp an ammeter around one igniter lead. Start Bake and watch the draw climb. Readings that stall low mean the bar is worn. Readings on target without flame point to a sticky valve or blocked ports.
Tip: No rise at all signals an open bar or broken lead. A rise that never reaches the threshold points to a weak bar.
Testing Numbers To Know
Hot-surface designs are tuned so that a healthy bar reaches a specific current range when hot. That is the signal that opens the safety valve. If your meter never gets there, the valve will stay closed even though the bar glows. Matching your readings to the spec sheet for your model removes the guesswork.
Burner, Cap, And Airflow
Pull the bottom panel and lift the flame spreader. Vacuum crumbs and brush the burner ports. Refit the spreader and cap fully seated and centered. This keeps the flame where the sensor expects it.
Model Differences Matter
Across model years you’ll see hot-surface bars for Bake and Broil, spark on the cooktop, and a few older pilots. Check the model code inside the door and grab the matching manual before you order parts. Samsung’s manual finder makes this simple: open the official user manual lookup and enter your model code.

Follow this clean workflow with basic tools.
Tools You’ll Need
A clamp ammeter, a #2 screwdriver, a nut driver set, a nylon brush, a flashlight, and leak-check solution. Gloves help when working near the burner and spreader.
Step 1: Safe Reset
Unplug for one minute, then power up. Set Bake to 350°F. Listen for the relay click. If the display crashes or the breaker trips, address power first.
Step 2: Confirm Gas
Locate the shutoff behind the range. Parallel with the pipe means open. After a cylinder change or service, run a cooktop burner for a minute to purge air, then retry Bake with the hood on.
Step 3: Clean And Reseat
Remove the oven floor, lift the spreader, clean ports, and reassemble flat with no wobble.
Step 4: Watch The Glow
A healthy bar reaches bright orange fast and the flame follows. A dull or flickering glow points to a failing part.
Step 5: Measure Amps
With Bake calling, clamp and read. Low, steady numbers confirm a worn bar. Replace with the exact assembly for your model.
Step 6: Inspect Wiring
Power off. Trace the harness from the bar to the valve and board. Look for browned insulation, loose crimps, or cracked ceramic. Reseat every connector.
Step 7: Judge The Valve
If amps meet spec yet no flame appears, test the valve coil against the service sheet. Replace the valve only after proving the bar is healthy.
When Broil Works But Bake Doesn’t
That split result usually means the bake bar is weak. Power and gas are present. Swap bars only if connectors and brackets match and only as a test. If the fault follows the bar, install a new bake assembly.
Spark Systems And Pilots
Some ovens light by spark. You should hear a crisp tick and see spark at the burner. Clean the electrode and set the gap. If you have a pilot, verify a steady blue tip touching the thermocouple.
Parts You May Need
Match parts by model number.
| Part | What It Does | When To Replace |
|---|---|---|
| Bake igniter assembly | Heats and signals valve | Glows but no flame; low amps |
| Broil igniter assembly | Lights the broiler | Broil won’t light; low amps |
| Oven safety valve | Opens at target draw | Igniter in spec but no flow |
| Control board/relay | Feeds the circuit | No output on call for heat |
| Wiring harness | Carries power | Open lead or burnt connector |
Specs And Manuals
Find the model tag inside the door frame or on the cabinet frame behind the drawer. Use that code to pull the exact manual and wiring sheet so you can match specs and diagrams while you test. Keep the sheet handy while you trace wires and record meter readings. Label connectors before pulling, carefully.
If the control is dark or resets, Samsung’s page on ranges that will not stay on is a handy reference when you chase power issues. That page explains display resets, breaker trips, and outlet tests. Use it to confirm basics.
Pro Help And Safety
If you smell gas during attempts to light, stop work, ventilate, and call your supplier’s emergency line. National bodies publish clear steps for emergencies and alarms; see the NFPA overview of residential fuel gas alarms for background on detection in homes.
After A Move Or Remodel
Two patterns are common. The shutoff gets left partly closed, which starves the oven while the cooktop still lights. Or the connector gets kinked. Open the valve fully, straighten the line, and retest. If symptoms remain, measure igniter draw.
Care Habits That Keep It Lighting
Wipe spills before they bake onto the burner. Keep foil off the floor and away from the spreader. Avoid banging heavy pans on the plate. Once a year, pull the bottom panel, brush the burner, and vacuum crumbs.
When Replacement Makes Sense
Glow bars are wear items. If you’ve had repeat failures, check line voltage and connector fit. Chronic low voltage or loose plugs shorten life. If the board shows heat damage, replacing the range can beat stacking parts.
Bottom Line
Most no-light complaints trace to a glow bar that still glows but won’t draw enough current to open the valve. Work the steps: power, gas, burner clean-up, then an amp test. With the right replacement matched to your model, Bake should fire reliably again.
