Magic Chef CGR3742CDW range Parts

For the Magic Chef CGR3742CDW gas range, replacing a gas oven igniter typically costs about $150 to $325 when a technician supplies the part and labor. If you do the repair yourself, the part is often the main cost, plus basic tools and time; use the CGR3742CDW owner’s manual for safety and access steps.

Typical cost breakdown

• DIY (part only): commonly $20 to $100+ depending on style and availability
• Professional service call + labor: commonly $100 to $250+
• Total installed cost: commonly $150 to $325 (higher if additional issues are found)

Scenario	What you pay for	Typical total
DIY replacement	Igniter + your time	$20 to $100+
Pro replacement	Igniter + labor + trip	$150 to $325
Complex diagnosis	Igniter plus extra troubleshooting/parts	$250 to $400+

What can raise the price

• The igniter is not the only failure (for example, weak spark/ignition system issues)
• Wiring damage or loose connections that need repair
• Multiple parts replaced during the same visit
• After-hours or expedited service

Before you buy an igniter

We recommend confirming symptoms so you do not replace the wrong part.

• If the oven won’t heat and you smell gas, the igniter can be weak or failed
• If the oven takes a long time to light, the igniter can be drawing too little current
• If the surface burners click normally but the oven does not light, focus on the oven ignition circuit

For this model, a common replacement is the igniter 74007498.

Why it matters

A weak igniter can prevent the oven burner from lighting reliably, which affects preheat time, baking temperature stability, and overall safety. The manual also emphasizes safe servicing practices and using proper replacement parts.

If your Magic Chef CGR3742CDW gas range oven will not turn on, the most common causes are an oven control setting issue, a power supply problem (needed for ignition), or an ignition system problem such as a weak igniter. Start with the basic checks in the CGR3742CDW owner's manual.

Quick checks first (fastest fixes)

• Confirm the oven selector (if your model has one) is set to Bake and the thermostat is set to a temperature.
• Allow for normal ignition delay; many gas ovens have about a 45-second delay before the main burner lights.
• Verify the range has power (plug seated, breaker not tripped, fuses OK). Even gas ranges need electricity for controls and electric ignition.
• Make sure any clock or timer knobs are in the correct positions; some ranges will not heat if the timer is set incorrectly.
• If your model uses a standing pilot, relight the pilot following the manual steps.

What to look for based on symptoms

What you notice	Most likely cause	What to do next
No heat and no ignition sounds	Control/timer setting or no power	Recheck settings and power supply
Clicking but no flame	Gas not reaching burner or ignition issue	Check gas supply; inspect ignition components
Smell of gas but no ignition	Ignition failure	Stop, ventilate, and have ignition serviced
Oven starts sometimes, then fails	Weak igniter or intermittent electrical connection	Inspect wiring and ignition parts

Parts that commonly fix “oven won’t turn on”

If the oven is not igniting reliably, these model-compatible parts are common repair paths:

• Igniter 74007498 (oven burner ignition)
• Oven sensor 12001655 (temperature sensing and control feedback)
• Spark module 8215557 (spark generation on models that use a spark system)

Why it matters

When the oven does not ignite, it is usually either not being allowed to run (settings, timer, power) or it cannot light the gas (pilot/igniter/spark). Checking the simple items first prevents unnecessary parts replacement and gets you to a safe, accurate repair faster.

On the Magic Chef CGR3742CDW gas range, the igniter location depends on what you are lighting: surface burners use a spark igniter at each burner, while the oven uses an ignition system at the oven burner under the oven bottom panel. See the CGR3742CDW owner's manual for the exact access steps.

Quick locations (surface vs. oven)

• Cooktop (surface burners): the igniter is at each sealed burner, right next to the burner head where the spark jumps to light the gas.
• Oven (bake burner): the igniter is mounted at the oven burner assembly, typically accessed by removing oven racks and lifting out the oven bottom panel.
• Broil area (if equipped): ignition components are in the broiler compartment area, separate from the bake burner.

How to access the oven igniter (common steps)

Before you start, let the range cool completely.

• Shut off electrical power to the range at the breaker (the manual calls out disconnecting power for service tasks).
• Remove oven racks.
• Remove the oven bottom panel (many ranges use rear catches or fasteners; lift the rear edge and slide to release).
• Locate the oven burner; the igniter mounts on or beside the burner where gas first lights.
• If you are replacing it, match the part by model and mounting style.

If you are replacing the oven igniter for this model, the listed part is the igniter 74007498.

What you will see (at a glance)

Area	What the igniter looks like	Typical symptom when it fails
Surface burner	Small spark electrode near burner	Clicking but no flame, or delayed ignition
Oven bake burner	Hot-surface igniter or ignition device at burner	Long preheat, no bake heat, gas smell without ignition

Why it matters

Finding the correct igniter location helps you troubleshoot the right system. A surface ignition problem usually points to a burner electrode, spark module, or switch, while an oven no-heat problem often points to the oven igniter or oven burner ignition circuit.
