Parts for Jenn-Air JDS8850AAB: 03 - Gas Controls Parts

This igniter switch controls power to the oven/range igniter so burners light reliably. It replaces a worn or failed switch to restore normal spark/ignition operation and help the appliance heat safely and consistently. What it does:

• Routes electrical power to the gas igniter when the control calls for heat
• Commonly replaced when the range/oven fails to light or sparks inconsistently
• Helps restore reliable ignition and prevent no-heat or intermittent-lighting symptoms
• Works as the electrical actuation point between the appliance control and igniter

• One igniter switch

• Disconnect power to the appliance before inspecting or replacing the switch
• For gas appliances, also shut off the gas supply and verify no leaks after service
• Inspect wiring and connectors for damage; use matching connectors and secure grounding

This factory screw secures appliance components to their mounting points. Replace missing, worn, or stripped hardware to restore a tight fit, proper alignment, and quieter operation across the affected assembly.

• Fastens panels, brackets, covers, or internal parts to the chassis or frame
• Helps maintain alignment and support, reducing rattle, vibration, or looseness
• Replaces missing or damaged screws that have backed out, broken, or stripped
• Restores secure mounting after service when original hardware is lost

• Disconnect power; shut off water or gas supplies before servicing
• Use the correct driver; start threads by hand to avoid cross-threading
• Match length and thread to the original location; do not substitute with longer hardware
• Tighten snugly; do not overtighten into plastic or thin metal

This spark module controls ignition for four surface burners and provides automatic reignition if a flame goes out. It generates the high-voltage spark and monitors flame for dependable lighting and consistent cooktop performance.

• Generates high-voltage pulses to ignite up to four surface burners
• Senses flame presence and automatically re-sparks if a flame is lost
• Helps stop sparking once flame is detected to reduce clicking
• Symptoms this part is involved with include: no spark on any burner, intermittent or weak spark, or continuous clicking after lighting

• Disconnect power and shut off gas before servicing
• Access is typically under the cooktop or behind a panel; mount the module securely away from heat and moisture
• Transfer wires one at a time to matching terminals; ensure ground/neutral connections are secure for proper flame sensing
• After reassembly, restore power and test each burner for ignition and that clicking stops when flame is present

This oven igniter is the glow-bar that lights the gas for the bake or broil burner. Replacing a weak or failed igniter restores dependable ignition and consistent oven heat, solving no-heat and long preheat complaints.

• Heats to ignite the gas burner in the oven cavity
• Draws the proper current to open the oven safety valve
• Common symptoms: oven won't heat, igniter glows but no flame, delayed or intermittent ignition, extended preheat times
• Restores reliable burner lighting for baking or broiling

• Disconnect power and shut off gas supply before servicing; allow the oven to cool
• Handle the igniter by the insulated base; avoid touching the fragile element
• Mount using the correct bracket and position the tip near the burner, as on the original
• Restore power and gas, then test for prompt, steady ignition
