Are all stove igniters universal?
No. Stove igniters are not universal; your Magic Chef CGR3742CDC gas range can use different igniter styles, mounts, and wire connectors depending on whether you’re lighting a surface burner or the oven burner. For the correct fit and safe ignition, match the igniter to your exact model and application using the CGR3742CDC owner's manual.
Even when two igniters look similar, small differences can prevent reliable lighting.
- Mounting hole pattern and bracket shape vary by range design
- Connector type can be plug-in or bare leads (splicing changes the repair)
- Igniter position and length affect how the gas lights
- Electrical characteristics (resistance and current draw) affect ignition timing
- Some ranges use spark ignition at the cooktop and a glow-bar style igniter in the oven
On many gas ranges, the cooktop uses a spark system (you hear clicking), while the oven uses a hot-surface igniter to open the gas valve and light the burner.
| Location | What you typically notice | Common related parts |
|---|---|---|
| Surface burner | Clicking spark at the burner | Surface burner igniter, spark module, igniter switch |
| Oven burner | Oven takes time to ignite, may not heat | Oven burner igniter, oven sensor |
If you need a model-matched replacement, use the parts list for CGR3742CDC and choose the correct style for your symptom, such as the igniter 74007498 (oven burner ignition) or the range surface burner igniter 74004053 (cooktop spark ignition).
- Confirm whether the problem is on the cooktop, in the oven, or both
- Look for visible cracks, heavy white oxidation, or a loose mounting bracket
- If the cooktop clicks but won’t light, clean and dry the burner cap and ports first
- If the oven won’t heat, allow for a normal ignition delay (many ovens pause briefly before lighting)
- Shut off power to the range before inspecting wiring or connectors
Using the wrong “universal” igniter can cause hard starts, delayed ignition, or repeated clicking because the igniter may not sit in the correct position or draw the correct current for your range’s gas ignition system.

How do I tell if my gas oven igniter is bad?
A bad oven igniter on your Magic Chef CGR3742CDC usually glows but stays too weak to open the gas safety valve, so the oven burner lights very slowly or not at all. If preheat stalls and you never get a steady flame, the igniter is the first part we check.
Turn the oven off and let it cool before you start.
- Set the oven to Bake and watch from a safe distance.
- If the igniter never glows, suspect the igniter, wiring, or a control issue.
- If the igniter glows but the burner does not light within about 45 seconds, the igniter is weak in most cases (a short delay is normal). See operating details in the owner's manual.
- If the burner lights but baking temperatures swing widely, also check the oven sensor.
- If you smell gas, turn the oven off and stop troubleshooting.
| What you see | Most likely cause | Next step |
|---|---|---|
| No glow at all | Open igniter or wiring problem | Inspect connections; test circuit |
| Dull red glow, no flame | Weak igniter | Replace igniter |
| Late ignition | Weak igniter or dirty burner | Clean burner area; replace if delay continues |
| Ignites but temps are off | Sensor issue | Test/replace sensor |
- Igniter 74007498 (oven burner igniter)
- Oven sensor 12001655 (for inaccurate or unstable temperatures)
A weak igniter can glow and still fail to open the safety valve, causing long preheat times or no heat. Replacing the correct igniter restores normal ignition and more consistent baking.

How much does it cost to replace an igniter on a gas stove?
For the Magic Chef CGR3742CDC gas range, igniter replacement cost is usually the price of the part plus labor if you hire service. On this model, common igniter-related parts run about $29 to $67 for the part itself; professional installation typically brings the total into the $150 to $300+ range.
- DIY (part only): typically $25 to $90
- Professional repair (parts + labor): typically $150 to $300+
- Higher totals happen when: multiple burners are affected, wiring is damaged, or the spark system needs more than one part
| Scenario | What you pay for | Typical total |
|---|---|---|
| Surface burner won’t spark | Surface igniter/electrode | $25 to $90 |
| Oven won’t heat (glow-bar style) | Oven burner igniter | $40 to $120 |
| Clicking or no spark on multiple burners | Spark module or switch issues | $150 to $350+ |
These are examples of ignition-related parts available for CGR3742CDC:
- Range surface burner igniter 74004053 (often used when one top burner will not spark)
- Igniter 74007498 (commonly tied to oven ignition problems)
- Spark module 8215557 (often involved when multiple burners click or stop sparking)
- Confirm whether the problem is surface ignition or oven ignition. Surface burners use a spark at the burner; the oven may use an igniter system depending on configuration.
- Look for simple causes: dirty burner ports, a wet igniter area after cleaning, or a loose wire connection.
- Match symptoms to the right component: one burner failing usually points to that burner’s igniter; multiple burners failing often points to the spark module or switch.
- Use the lighting and operation guidance in the Owner's manual to verify normal ignition behavior and safety steps.
An igniter that is weak or not sparking can prevent proper gas ignition, which leads to delayed lighting, no-heat conditions, or repeated clicking. Fixing the correct ignition component restores reliable burner lighting and normal cooking performance.
