• Can resolve ignition issues caused by physical damage or buildup on the ignitor area

• One cover ignitor

• Disconnect power (and gas supply on gas appliances) before starting any repair
• Handle the ignitor assembly carefully; avoid touching the ceramic or ignitor tip
• Use basic hand tools; ensure the cover seats properly without forcing or cracking it
• After installation, restore power/gas and test the burner or oven according to the appliance manual

This small threaded component controls gas flow to LP gas burners and is located within the burner assembly. Replace when burners produce yellow flames, won't ignite properly, or have uneven flame patterns.

Weak or uneven flames on your gas range? A clogged or damaged orifice spud restricts gas flow to the burner. Simple replacement restores proper flame size.

Burner orifice spud regulates gas flow to the burner on your range or cooktop. Replace if missing, damaged, or when converting between LP and natural gas.

Weak or uneven flames on LP gas? This range burner orifice spud meters propane flow for steady, consistent flames. Restores proper gas delivery.

This surface burner control valve regulates gas flow from the manifold to a cooktop burner. The 270-degree rotation provides smooth flame adjustment. Replace a worn valve to restore reliable ignition and precise, consistent flame control. What it does:

• Meters gas to one surface burner as you turn the knob (270-degree sweep)
• Supports proper ignition and steady flame across low-to-high settings
• Common fix for a burner that won't light or has weak/inconsistent flame
• Helps when the control knob is stiff, binds, or won't align cleanly at Off

• One surface burner valve (270-degree rotation style)

• Disconnect power and shut off the gas supply before servicing
• Access the manifold; note valve orientation and stem position before removal
• Transfer the burner orifice/spud and any mounting hardware from the original valve; use an approved gas-rated thread sealant where specified
• After reassembly, leak-test all connections with a soap-and-water solution and verify proper burner operation

• This is the 270-degree rotation style; match rotation style and stem/shaft type to your original valve for correct knob alignment and flame control

Replace a faulty range burner valve if your burner won't ignite, has weak flames, or won't turn off. Moderate DIY repair in about 1 hour with basic tools.

Weak or uneven oven flame? This oven orifice spud secures the gas orifice and directs proper gas flow to the burner for consistent heating.

Panel mounting screw secures trim, bezels, and internal components on ranges and cooktops. Replace when stripped, corroded, or missing to restore fit.

Fix an oven that won't heat or takes too long to reach temperature. This igniter glowbar opens the gas valve to ignite the burner. DIY-friendly repair.

The Oven Igniter is an OEM replacement part for GE ovens, designed to ignite the bake igniter to start the heating process. This part is responsible for creating the spark that ignites the gas, providing the heat needed to cook and bake food. Over time, the oven igniter can wear out or become damaged, which can prevent the oven from heating.

Symptoms of a bad Oven Igniter include:

• The oven not heating up at all.
• The oven taking longer than normal to heat.
• Gas smell in the oven due to gas being released without ignition.
• A clicking sound without the oven igniting.

Causes of a bad igniter can include normal wear and tear over time, exposure to excessive heat or moisture, or physical damage from impact or mishandling.

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 

IMPORTANT: The connector plug may need to be cut off and igniter wires connected to range wires using porcelain wire connectors.

Burner deflector guard for gas ranges. Installs around burner assembly to direct heat and protect components. Replace if cracked, warped, or missing.

This broil shield protects the oven interior above the broiler, helping direct heat and shielding the oven cavity from intense broiling temperatures for safer, more consistent broiling results. Durable metal construction resists warping. What it does:

• Shields the oven top and components from direct broiler heat to prevent damage and discoloration
• Helps maintain more even broiling by directing heat where food is placed
• Reduces the risk of flare-ups reaching wiring or insulation behind the oven liner
• Restores proper clearance between the burner and oven liner for safe operation

• One broil shield

• Disconnect power (and gas, if applicable) and allow the oven to cool completely before starting
• Remove oven racks and access the broiler area to unfasten and replace the shield using basic hand tools
• Inspect mounting tabs and surrounding liner; replace any damaged clips or screws as needed

This terminal cover protects the oven/range power connection by covering the appliance's rear terminal block, helping prevent accidental contact and keeping wiring secure. It's a direct-replacement exterior cover for the unit's power terminals. What it does:

• Reduces risk of accidental contact with live terminals when the access panel is opened
• Keeps the terminal area tidier and helps prevent debris buildup around connections
• Commonly replaced when the original cover is cracked, broken, or missing

• One terminal cover

• High-level replacement: remove rear access panel to access the terminal block, then replace the cover and secure with existing screws
• Always disconnect power (unplug or switch off the breaker) before servicing electrical components
• No special tools required beyond a screwdriver; follow OEM instructions if available
