How much does it cost to replace a gas oven igniter?
For the Magic Chef CGR3760ADW gas range, replacing a gas oven igniter typically costs about $150 to $325 when a technician supplies the part and labor. If you do it yourself, the part is often the main expense; for this model, a common replacement is the oven igniter 12400035.
Costs vary by service rates and how hard the igniter is to access, but these ranges are common for a gas range repair:
- DIY parts-only: about $20 to $100 (model-specific parts can cost more)
- Service call / diagnostic: often $75 to $150
- Labor (if approved repair): often $75 to $175
- Total professional replacement: commonly $150 to $325
| Repair approach | What you pay for | Typical total |
|---|---|---|
| DIY | Part only | $20 to $100 |
| Pro repair | Part + labor + service call | $150 to $325 |
| Complex visit | Extra troubleshooting or access issues | $300+ |
These factors usually move the total up or down:
- Correct part match for CGR3760ADW (igniters are not universal)
- Access time (some ranges require more disassembly)
- Wiring condition (burned connectors can add time and parts)
- After-hours or same-day service pricing
- Additional failures (for example, weak gas flow or temperature sensing issues)
A weak igniter is one of the most common reasons a gas oven will not heat or takes a long time to light. Replacing it restores reliable ignition, helps the burner light consistently, and prevents repeated “clicking” attempts and uneven baking.

How old is my magic chef oven?
Your Magic Chef gas range model CGR3760ADW is as old as the manufacture date encoded in its serial number, not the model number itself. We date it by finding the data plate, recording the serial number, then decoding the date code used by the manufacturer.
Look for a data plate or rating label in one of these common spots:
- Oven frame behind the storage drawer (pull the drawer out)
- Door jamb area (around the oven door opening)
- Under the cooktop (lift-up top on some ranges)
- Back panel of the range
Once you have the serial number, use this process:
- Write down the full serial number exactly as shown (letters and numbers)
- Look for a date code pattern (often the first few characters)
- Compare the code to common formats (week/year or month/year)
- If the label lists a “MFG” date, use that directly
- If the label lists only serial, use the serial to determine the date range
Serial formats vary by manufacturer and era, but these are the most common patterns:
| What you see in the serial | Usually means | Example outcome |
|---|---|---|
| Week + year code | Build week and year | “12 09” = 12th week of 2009 |
| Month letter + year digit | Build month and year | “C7” = March of a year ending in 7 |
| Full “MFG DATE” printed | Exact manufacture date | “MFG 05/2012” |
Knowing the manufacture date helps us match the correct replacement parts and revisions for your CGR3760ADW, especially for ignition and gas components.
If your range is older and showing symptoms like slow ignition or uneven baking, these parts are commonly involved:
- Oven igniter 12400035 (weak igniter can prevent the oven burner from lighting)
- Range surface burner igniter 74004053 (no spark or intermittent spark)
- Oven probe 12001655 (temperature swings or inaccurate baking)

How to fix an igniter on a gas oven?
On the Magic Chef CGR3760ADW gas range, an oven that will not ignite is usually caused by a weak oven igniter, a dirty burner/ignition area, or a gas control issue. Start with safe cleaning and a quick visual check; if the igniter does not glow bright or the burner never lights, replacement is the most common fix.
- Turn the oven control to OFF and let everything cool completely.
- Shut off the gas supply at the range shutoff valve.
- Unplug the range (or switch off the breaker) before touching wiring.
- If you smell gas at any point: stop, ventilate, and do not operate the range.
- Remove the oven bottom panel (if accessible) and clear crumbs and grease around the burner.
- Make sure the burner is seated straight and not blocked at the ports.
- Check the igniter wire connector for looseness, heat damage, or corrosion.
- If the oven igniter glows but the burner lights slowly, clean the burner area and retest.
| What you see | Most likely cause | What we recommend |
|---|---|---|
| No glow from igniter | Failed igniter, broken wire, or no power to igniter | Inspect wiring; replace igniter if wiring is intact |
| Igniter glows dull orange, burner will not light | Weak igniter (common) | Replace igniter |
| Burner lights after a long delay | Weak igniter or restricted burner ports | Clean burner area; replace igniter if delay continues |
| Burner lights but temperature is erratic | Sensor/probe issue | Test/replace oven probe |
- Oven igniter 12400035 (most common fix for no-heat or delayed ignition)
- Oven valve WP74006427 (less common; suspect if igniter is proven good but gas never opens)
- Oven probe 12001655 (helps when heating is inconsistent rather than no-ignite)
A weak igniter can prevent the gas valve from opening correctly, causing no heat or delayed ignition. Fixing ignition problems quickly helps restore normal baking performance and reduces repeated clicking, delays, and uneven cooking.
