How to make sure you get the right part

Use this quick checklist before you buy:

• Confirm the appliance model number is MGR5770ADW (from the range frame label)
• Match the part by function (bake ignition, surface ignition, oven temperature sensing)
• Compare the part number and description to your symptom
• Check whether you need a related item (mounting screws, gasket, wiring connector)
• For gas components, plan for leak testing after installation

Common MGR5770ADW parts customers replace

Symptom	Likely part type	Example part for this model
Oven will not heat, no ignition	Oven burner igniter	Oven igniter 12400035
Surface burner won’t spark	Surface burner igniter	Range surface burner igniter 74004053
Oven temperature is erratic	Oven temperature sensor	Sensor (part ID 12001655)

Yes. Maytag makes gas ranges, including the Maytag MGR5770ADW gas range family, and they are designed for everyday cooking tasks like baking, broiling, and stovetop simmering. If you are shopping parts for this model, matching the exact model number helps ensure proper fit and safe operation.

What “Maytag gas range” typically includes

Most Maytag gas ranges use a gas cooktop and a gas oven burner system, supported by common service parts such as igniters, sensors, and door seals.

• Gas surface burners with spark ignition
• A gas oven burner that lights using an igniter
• Temperature sensing for bake control
• An oven door gasket to help hold heat in
• Replaceable wear items like bulbs and switches

Common parts customers replace on MGR5770ADW

If you are repairing ignition or heating issues, these are some of the most frequently replaced parts we see for this Maytag gas range:

Symptom	Common part involved	Example part for this model
Oven will not heat or takes too long to ignite	Oven igniter	Oven igniter 12400035
One surface burner will not click or light	Surface burner igniter	Range surface burner igniter 74004053
Oven temperature seems off	Sensor	Sensor 12001655
Heat leaks, uneven baking, or odor from door	Door gasket	Door gasket WPW10162384

Why it matters

Maytag makes multiple gas range designs, and parts are model-specific. Using MGR5770ADW (not just “Maytag range”) helps you avoid ordering the wrong igniter, sensor, or gasket and reduces repeat repairs.

A gas stove (like the Maytag MGR5770ADW gas range) is made up of cooktop burner parts that create and control the flame, plus oven components that ignite, regulate temperature, and vent heat. Knowing the main parts helps you pinpoint what to clean, adjust, or replace when performance changes.

Main parts you will see on the cooktop

• Burner grates (support cookware)
• Burner caps (shape and stabilize the flame)
• Sealed burners or burner bases (mix gas and air)
• Igniters (spark to light the burner)
• Control knobs and valve stems (control gas flow)

Main parts inside the oven

• Bake burner and ignition system (lights the bake flame)
• Temperature sensor (helps regulate oven temperature)
• Oven door gasket (helps seal heat in)
• Door glass and hinges (insulation, visibility, safe opening)
• Oven light and lens (interior visibility)

Common “part to symptom” matches

Symptom	Most likely area	Example part for MGR5770ADW
Oven will not heat	Oven ignition	Oven igniter 12400035
Surface burner will not spark	Cooktop ignition	Range surface burner igniter 74004053
Oven temperature swings	Temperature sensing	Sensor 12001655
Heat leaks around door	Door sealing	Door gasket WPW10162384
Oven light out	Lighting	Oven bulb 8009

Why it matters

When you can name the part group (surface ignition, oven ignition, temperature sensing, door sealing), troubleshooting gets faster and you avoid replacing the wrong component. For example, a weak oven igniter often causes no-heat or slow preheat even when the gas supply is fine.

If your Maytag MGR5770ADW gas range oven will not heat on Bake, the most common cause is a weak or failed oven igniter that cannot pull enough current to open the gas valve. A bad temperature sensor or gas valve can also prevent heating.

Quick checks we recommend first

• Confirm the oven is set to Bake (not Broil) and the temperature is above room temp.
• Watch the igniter through the oven bottom vents: it should glow bright and the burner should light shortly after.
• If the igniter glows but the burner never lights, the igniter is often too weak.
• If nothing glows, check power to the range and wiring connections.
• If the oven heats inconsistently, suspect the sensor.

Parts that most often fix “no heat” on Bake

Symptom	Most likely part	What you’ll notice
Broil works, Bake does not	Oven igniter 12400035	No glow, or a dull glow with no ignition
Oven heats but temp is wrong	Sensor 12001655	Overheats, underheats, or cycles oddly
Igniter glows normally but no gas flow	Oven valve WP74006427	No burner ignition even with a strong glow

Why the igniter matters on a gas oven

On many Maytag gas ranges, the bake igniter is part of the safety circuit. It must draw enough electrical current to open the oven gas valve. When it gets weak, it may still glow but the valve stays closed, so the burner never lights.

Safety and repair tips

• Shut off power at the breaker before accessing wiring.
• Shut off the gas supply before replacing gas-carrying parts.
• Handle the igniter carefully; it can crack if bumped.
• If you smell gas, stop and have the range checked before continuing.
