How do I get my gas oven to ignite?
On the Magic Chef CGS1740ADH, the oven uses a pilotless ignition system (a glow bar igniter). After you set Bake, it’s normal for the burner to ignite after about 45 seconds; the range will not ignite the oven during a power failure.
- Confirm the range has electrical power (the igniter needs electricity to heat up).
- Set the oven to Bake and a temperature; wait at least 45 seconds for ignition.
- Make sure the oven door is closed during preheat.
- If you smell gas, turn the oven off and wait 5 minutes before trying again.
- Do not try to manually light the oven burner on this pilotless system.
Most “no-ignite” problems come down to power, the igniter, or gas flow.
| Symptom | Most likely cause | What we recommend |
|---|---|---|
| No heat and no ignition after 60 to 90 seconds | Weak or failed igniter | Replace the igniter 74007498 |
| Oven will not work at all during an outage | No power to igniter | Restore power; check breaker/fuse |
| Strong gas odor | Gas accumulated | Turn off, ventilate, wait 5 minutes |
| Surface burners spark but oven won’t light | Oven ignition circuit issue | Check wiring connections; service if needed |
A pilotless (glow bar) ignition system is designed to delay ignition briefly while the igniter heats up. Waiting the full ignition delay and ensuring proper power prevents nuisance “no heat” complaints and helps avoid unsafe gas buildup.
Use the CGS1740ADH owner’s manual for the exact bake/broil operating steps, safety cautions, and normal ignition timing for your range.

How much does it cost to repair a gas oven igniter?
For the Magic Chef CGS1740ADH gas range, repairing an oven igniter usually means replacing the igniter; total cost is typically $150 to $325 with a service technician (parts plus labor). DIY cost is usually $50 to $120 when you only buy the part.
- Igniter part: commonly $50 to $100 for this style of range igniter
- Service call / diagnostic: commonly $75 to $150
- Labor (replacement): commonly $75 to $175
- Total professional repair: commonly $150 to $325
| Repair approach | What you pay for | Typical total cost |
|---|---|---|
| DIY replacement | Part only (plus basic tools) | $50 to $120 |
| Professional repair | Part + trip/diagnostic + labor | $150 to $325 |
- Whether the igniter is the real failure (sometimes the issue is wiring, a control, or gas flow)
- Access time (some ranges require more disassembly)
- Local labor rates and minimum trip charges
- Related parts needed (for example, damaged connectors or mounting hardware)
Before buying parts, we use these practical checks that match how pilotless ignition ranges operate:
- The oven is slow to light (often longer than the normal short delay)
- You smell gas briefly but the burner does not light promptly
- The igniter glows but the burner flame is weak or delayed
- The oven will not heat at all even though the control is set to bake
- Power issues: this range will not operate during a power failure (ignition needs electricity)
For model-specific access and safety steps, follow the CGS1740ADH owner’s manual.
If the diagnosis points to the igniter, the correct replacement is the igniter 74007498. If the oven still will not light after igniter replacement, a gas flow component such as the oven valve can also be involved.
| Symptom | Most common fix |
|---|---|
| No heat, no ignition | Replace igniter |
| Igniter works but burner never opens | Check gas valve and wiring |
A weak igniter can prevent the oven burner from opening correctly, causing long preheat times, temperature swings, and unreliable baking performance.

How to tell if a gas igniter is bad?
A bad gas igniter on our Magic Chef CGS1740ADH range usually shows up as delayed ignition (long preheat), no ignition, or repeated clicking with no flame. If the igniter is cracked, stays dim, or the burner never lights, replacement is typically the fix.
- Oven takes much longer than normal to heat, or never reaches temperature
- You hear ignition activity but the burner does not light
- Igniter does not glow at all, or glows weakly instead of bright
- You smell gas without ignition; stop and follow the safety steps in the CGS1740ADH owner’s manual
- Surface burner will not light when the ignitor is wet, soiled, damaged, or the small port under it is blocked (common on sealed burners)
- Power and settings: Confirm the range has power and the control is set to Bake or Broil.
- Visual inspection: Look for cracks, white spots, or a broken igniter tip.
- Clean and dry (surface burners): The manual notes burners may not light if the ignitor is soiled or wet, or if the small port beneath the ignitor is blocked. Clean carefully and let everything dry fully.
- Watch the ignition sequence: A properly adjusted, clean burner should light within a few seconds.
| What you see | Most likely cause | What to do next |
|---|---|---|
| No glow at all | Failed igniter, wiring issue, control issue | Inspect wiring; consider replacing igniter |
| Weak/dull glow, slow ignition | Worn igniter (common) | Replace igniter |
| Clicking continues until knob moved off LITE | Normal surface-burner behavior | Turn knob from LITE after ignition |
| Burner will not light after cleaning | Bad igniter or blocked port | Recheck port; replace igniter if needed |
- For oven ignition issues, the oven burner igniter is a common fix: igniter 74007498
- For surface burner spark issues, the igniter at the burner can be the culprit: range surface burner igniter 74004053
A weak igniter can delay ignition and cause gas to flow longer before lighting. That creates poor performance and a safety concern, so addressing ignition problems promptly keeps baking and broiling consistent and safer.
