Magic Chef 3110PRW gas range Parts

On the Magic Chef 3110PRW gas range, a bad oven igniter usually shows up as no bake heat, very slow ignition, or an igniter that glows but never lights the burner. In many cases the igniter is weak and cannot draw enough current to open the gas safety valve.

• The igniter glows, but the burner never lights.
• The burner lights after a long delay (often 30 to 90 seconds or more).
• The oven temperature is inconsistent because ignition is intermittent.
• You smell gas briefly before ignition (shut the oven off and ventilate).
• The igniter does not glow at all (could also be wiring, control, or safety valve).
• The igniter looks cracked, chalky, or damaged.

1. Watch the ignition sequence: Set Bake and look through the broiler/bottom access area if your range design allows. A healthy igniter typically glows bright and the burner lights shortly after.
2. Listen and time it: If it takes a long time to light, the igniter is commonly the cause.
3. Inspect the igniter: With power off, look for visible damage and check that the connector is seated.

A weak igniter can glow but still be bad. The most reliable check is measuring igniter current draw with a clamp meter.

For this model, the correct replacement is the oven igniter 12400035. Replacing a weak igniter is the most common fix when the igniter glows but the burner will not light.

A weak igniter can prevent the gas safety valve from opening fully, so the oven will not heat or will heat unpredictably. Fixing ignition restores normal bake performance and helps prevent repeated failed ignition attempts.

Replacing a gas oven igniter on a Magic Chef 3110PRW typically costs $150 to $325 when a technician supplies the part and labor; most jobs land around $185 to $265. If you do the repair yourself, the main cost is the igniter itself (plus basic tools).

Costs vary most by service call rates, how hard the igniter is to access, and whether wiring/connectors are damaged.

• DIY parts-only: usually $20 to $75 for many ranges; OEM-style parts can cost more
• Professional labor: commonly 1 to 2 hours plus a service call
• Total pro repair: often $150 to $325 (higher if extra diagnosis or wiring repair is needed)

These are the most common add-ons we see with gas range igniter repairs:

• A second trip (part not on the truck)
• Brittle or burned wire connectors that need repair
• Seized mounting screws or damaged brackets
• Additional burner issues (weak gas valve, clogged burner tube)
• Aftermarket igniter mismatch (wrong style or connector)

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 promptly helps restore normal bake performance and reduces repeated clicking and delayed ignition.

For the Magic Chef 3110PRW, the model-specific replacement part we commonly see listed is the oven igniter 12400035.

On the Magic Chef 3110PRW gas range, the oven should ignite after you turn the oven control to a bake temperature and the igniter heats up; you typically need to keep the oven knob pushed in for about 5 to 10 seconds so the safety valve stays open and the burner can light.

• Confirm the range has gas: other burners should light normally.
• Set the oven to BAKE (not BROIL) and choose a temperature.
• Push in and hold the oven knob (if your model uses a push-to-hold safety feature) for 5 to 10 seconds.
• Watch and listen: the igniter should glow and you should hear a soft gas “whoosh” when the burner lights.
• If the igniter glows but the burner never lights, the igniter is often weak and needs replacement.

If your oven is not lighting reliably, the most common fix is replacing the oven igniter.

• Oven igniter 12400035

A gas oven relies on the igniter to heat up enough to open the safety gas valve. When the igniter is weak, you can see it glow but still get no flame, long preheat times, or intermittent ignition.

Gas oven igniters on the Magic Chef 3110PRW typically last 3 to 5 years with normal home use. Heavy baking, frequent self-clean cycles, and long preheat times can shorten igniter life; light use and good airflow around the burner can help it last longer.

Most hot-surface igniters fail gradually (slower ignition first, then no ignition). These factors have the biggest impact:

• Oven usage frequency (daily baking vs. occasional use)
• Long preheats and extended bake times
• Grease and food spills that bake onto the burner area
• Power quality (surges can stress the igniter)
• Poor burner ignition that keeps the igniter glowing longer than normal

If your Magic Chef gas range starts acting like this, the igniter is a top suspect:

• Bake or broil takes longer to light than it used to
• You smell gas briefly before ignition (shut it off and ventilate)
• Oven temperature is inconsistent because the burner cycles poorly
• Igniter glows but the burner does not light
• Oven will not heat at all

• Turn off power to the range before inspecting anything.
• Look for visible cracking, white spots, or damage on the igniter.
• If the igniter glows but ignition is slow, replacement is usually the fix.
• Use a meter test only if you are comfortable with electrical checks; our guide how to use a multimeter to test electrical parts video helps.

If you are replacing the igniter for this model, match it by model number and part listing; the common replacement on this page is the oven igniter 12400035.

A weak igniter can keep the gas valve from opening fully or quickly, leading to no-heat problems, long preheats, and unreliable baking results. Replacing it early often restores normal ignition and temperature control.
