Jenn-Air Range JDS8850BDB Won't start or doesn't start

The Top Burner Igniter is an OEM part for Whirlpool gas cooktops and ranges. This thin metal coil provides the spark to light the burner flames during startup. It is a spark electrode with a male spade connection.

Causes involve cracking of fragile ceramic insulator casings allowing moisture ingress, compromised electrical connections cutting off sparking ability, or general wear reducing spark output strength.

Symptoms of failure consist of:

• Inability to light one or more front gas burners
• Click sounds but no flame present when turning burner knob
• Safety issues arising from unlit gas accumulating

This is a genuine Whirlpool OEM replacement this part is also compatible with Maytag, Jenn-Air and some Kenmore models.

This surface burner head is a genuine Whirlpool part, sold individually. It can be used as a replacement part for a gas range. This surface burner head provides structure and support for the surface burner cap and the ignition, which all work in conjunction to ignite the spark plugs and power on the burner.Signs of damage to this part will include a gas ignition that glows but will not ignite, a gas range that will not start at all, or a heating element that will not heat up the appliance. If any of these signs of damage occur and are directly attributable to the surface burner head, the component should be removed and replaced with this genuine OEM replacement part.This is an OEM part sourced directly from the manufacturer. It is sold individually. This surface burner head is compatible with the following appliance brands: Whirlpool, Jenn Air, and KitchenAid.

The Large Burner Head is an OEM part for Whirlpool gas ranges and cooktops. It is designed to fit over the burner base and distribute the gas evenly for efficient and consistent heating.

Causes of a bad burner head can include blockages from food debris or residue buildup, warping or damage from high heat exposure, or general wear and tear over time.

Symptoms of a bad Large Burner Head include:

• Uneven heating or hot spots on the burner
• Yellow or irregular flame patterns
• Difficulty igniting the burner or keeping it lit
• Loud popping or hissing noises during operation

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

This dual-burner surface spark igniter lights two adjacent gas burners on your range or cooktop. Replacing a worn or cracked igniter restores quick, reliable ignition and consistent lighting across the pair, reducing long clicking or failed starts.

• Generates a high-voltage spark at two electrodes to ignite gas at both burners in the pair
• Helps resolve: surface burner won't light, only one of the two lights, intermittent/weak spark, or excessive clicking before ignition
• Often needed when ceramic insulators are cracked, tips are damaged, or the igniter is shorting to ground
• Designed for units that use a shared dual-burner igniter assembly

• Disconnect electrical power and shut off gas before servicing
• Remove grates, burner caps, and bases to access; lift the cooktop or burner deck as required
• Transfer any mounting hardware and align electrodes with burner ports; avoid stressing the ceramic
• Reconnect leads securely, reassemble, and test burner ignition

This small surface burner assembly replaces a worn or damaged top burner on your gas range or cooktop, restoring quick ignition and an even flame so the small burner heats predictably for simmering and everyday cooking.

• Distributes gas through the burner ports to create a steady, controllable flame at the small-burner position
• Works with the igniter/orifice holder to light reliably
• Common symptoms: burner won't light or only clicks, weak or uneven flame, yellow tips, delayed ignition, or flame that sputters out
• Visible cracks, warping, or heavy corrosion on the burner head

• Shut off gas supply and power; allow the cooktop to cool completely before servicing
• Remove grate and cap, then take out the old burner assembly; retain any screws or brackets as required by your model
• Align the new assembly over the orifice and igniter; seat fully and secure per the manufacturer's instructions
• Restore gas and power, then check for proper ignition and flame; verify there are no gas leaks
