Maytag CHG9830BAE gas freestanding range Parts

On the Maytag gas freestanding range model CHG9830BAE, 5Ab indicates Sabbath mode is turned on. In this mode, the range limits certain display and control functions; using Cancel/Off exits Sabbath mode and returns the oven to normal operation.

What to do when you see 5Ab

• Press Cancel/Off once and wait a few seconds to see if the display returns to the normal clock or idle screen.
• If the oven was running, confirm the burner shuts off and the oven begins cooling.
• Try starting Bake again and verify the oven ignites and heats normally.
• If the display returns to 5Ab after power flickers, reset the range by turning off the breaker for 1 minute, then restore power.
• If the oven still will not heat after exiting Sabbath mode, troubleshoot ignition and temperature sensing.

If the oven will not heat after Sabbath mode is off

Sabbath mode can look like a heating problem, but if the oven still will not ignite, these parts are common causes on gas ranges:

Symptom	Most likely area	Example part for CHG9830BAE
No glow/ignition, no heat	Oven ignition circuit	Oven igniter 12400035
Ignites sometimes, weak heat	Igniter getting weak	Oven igniter 12400035
Temperature is inaccurate	Sensor/probe issue	Oven probe 12001655

Why it matters

Sabbath mode is designed to change how the range responds to button presses and display updates. If it is enabled accidentally, it can prevent normal day-to-day cooking behavior and make the oven seem unresponsive.

To take your Maytag CHG9830BAE gas freestanding range out of lock mode, press and hold the Lock or Key pad for about 3 to 5 seconds until the lock indicator turns off. Once the indicator clears, the cooktop and oven controls should work normally.

Quick unlock steps (most common)

• Make sure the control panel is powered on (display lit).
• Press and hold Lock, Control Lock, or the Key symbol.
• Keep holding for 3 to 5 seconds.
• Wait for a beep or for the lock icon/light to turn off.
• Test a simple function (for example, turn on the oven light).

If it still will not unlock

Lock behavior varies by range control style, so use these checks that apply to CHG9830BAE-STYLE controls:

• Try a different pad name: some panels label it Lock, others show a key icon.
• Cancel first: press Cancel/Off, then press and hold the lock pad again.
• Power reset: unplug the range or switch the breaker off for 1 minute, restore power, then try the lock pad again.
• Stuck key: wipe the keypad area with a barely damp cloth and dry it; a stuck or wet pad can keep the lock engaged.

When a part is likely involved

If the lock will not toggle after a power reset and the keypad seems unresponsive, the issue is usually in the control interface (not a burner or igniter). Use this table to narrow it down.

What you see	Most likely cause	What we recommend
Lock icon stays on, most keys do nothing	Keypad/control not registering input	Try cleaning and power reset; if unchanged, schedule service
Only oven light will not respond	Failed light switch or bulb circuit	Check oven bulb 8009 and the light switch wiring
Display works but oven will not heat (not a lock issue)	Ignition or gas/temperature sensing problem	Follow oven wont heat troubleshooting gas range problems video

Why it matters

Control lock is a safety feature that prevents accidental starts and unwanted temperature changes. If the lock will not release, it can also point to a keypad or control problem that affects normal oven operation.

Replacing an igniter on a Maytag gas range like model CHG9830BAE typically costs $100 to $350 total (part plus labor). If you do it yourself, the cost is usually the igniter price only, plus basic supplies; a service call adds most of the expense.

Typical cost breakdown

Costs vary by whether you mean the oven igniter (for bake/broil) or a surface burner igniter (for the cooktop).

• DIY parts-only: usually $25 to $120
• Professional labor: commonly $75 to $200
• Service call / trip charge (if applicable): commonly $75 to $150
• Total installed cost: usually $100 to $350

Replacement type	What it affects	Typical DIY cost	Typical installed cost
Oven igniter	Oven won’t heat, slow preheat, no flame	$25 to $120	$150 to $350
Surface burner igniter	Burner won’t spark/clicks but won’t light	$20 to $90	$100 to $250

Parts that commonly apply to CHG9830BAE

If your oven is not lighting or takes a long time to ignite, the oven igniter is a common fix for this model.

• Oven igniter 12400035 (common for oven not heating or delayed ignition)
• Range surface burner igniter 74004053 (common for a cooktop burner that won’t spark)
• Spark module 12001596 (common when multiple burners stop sparking)

What changes the price the most

These factors usually determine whether you land near the low end or high end of the range:

• Which igniter failed: oven igniters often take longer to access than a single cooktop igniter
• How many burners are affected: one burner vs. multiple burners (spark module or switch issues)
• Access and disassembly time: seized screws, heavy cooktop, or tight wiring
• Diagnosis time: confirming igniter vs. gas valve, wiring, or control issue

Why it matters

A weak igniter can prevent the gas valve from opening fully, leading to no heat or very slow preheating. Replacing the correct ignition component restores normal oven temperature control and reliable burner lighting.

On a Maytag gas freestanding range model CHG9830BAE, a bad oven igniter usually shows up as an oven that will not heat, heats very slowly, or never reaches set temperature even though the igniter glows. The most reliable sign is delayed ignition (often 60 to 90+ seconds) or no ignition at all.

Quick checks you can do safely

• Watch the igniter during a bake start: it should glow bright and the burner should light shortly after.
• Time the ignition: if it takes longer than about 60 to 90 seconds to light, the igniter is typically weak.
• Look for a dull glow: a weak igniter often glows, but not bright enough to open the gas valve fully.
• Notice temperature symptoms: long preheat, uneven baking, or the oven cycling off before reaching temp.
• Smell check: if you smell gas without ignition, stop the test, turn the oven off, and ventilate the area.

What “bad igniter” symptoms look like vs other problems

Symptom	Most common cause	What to check next
Igniter glows, burner never lights	Weak igniter	Replace oven igniter 12400035
No glow at all	Igniter open, wiring issue, control issue	Inspect wiring connections; test igniter continuity
Burner lights after a long delay	Weak igniter	Replace oven igniter 12400035
Oven heats but temperature is inaccurate	Sensor/probe issue more likely	Consider oven probe 12001655

Why it matters

A weak hot surface igniter can glow but still fail to draw enough current to open the oven safety gas valve properly. That leads to slow ignition, poor heating performance, and unreliable baking results.

When replacement is the right next step

Replace the igniter when you see one or more of these conditions:

• Igniter glows but the burner does not light
• Ignition is consistently delayed (roughly 60 to 90+ seconds)
• Oven struggles to reach temperature or preheats much longer than normal
