Bosch Cooktop NGMP077UC Parts

This burner cap is the replaceable top piece for a gas cooktop or range burner that helps shape and protect the flame for reliable cooking. Replaces a worn or damaged cap to restore even heat and stable ignition. What it does:

• Evenly distributes the burner flame for consistent cooking heat
• Protects the burner head from spills, debris, and physical damage
• Helps maintain proper flame shape and prevents erratic ignition
• Can reduce noisy or uneven flames caused by a cracked or warped cap

• Ensure the appliance is turned off and completely cool before handling
• Lift off the old cap and seat the new cap squarely on the burner base; no special tools typically required
• Inspect surrounding burner parts for damage or debris and clean before reinstalling

This thermocouple is the flame-sensing safety switch used on gas ranges/ovens. It detects the pilot or burner flame so the gas valve only stays open when a flame is present, helping restore reliable ignition and safe operation. What it does:

• Senses the presence of a pilot or main burner flame and signals the gas valve to stay open
• Stops gas flow when a flame is not detected to prevent unsafe gas buildup
• Common symptom fix: oven or range won't stay lit or the pilot won't remain lit
• Replaces a worn or damaged flame sensor to restore normal ignition behavior

• Turn off gas supply and electrical power before starting any work
• Position the thermocouple tip so it is properly seated in the pilot flame; avoid excessive bending or kinking of the tube
• Use correct fittings and tighten connections securely; inspect for gas leaks after installation

Replace a worn or leaking burner valve stem to restore reliable gas flow and heat control. Fixes burners that won't light or adjust properly.

This thermocouple is a replacement flame-sensing probe that detects the burner/pilot flame so the gas valve operates correctly, helping restore reliable ignition and safer operation for compatible gas ovens and ranges. What it does:

• Senses presence of the burner/pilot flame and signals the gas valve to stay open.
• Stops gas flow when a flame is not detected, helping prevent unburned gas buildup.
• Replaces a failed probe that can cause the oven or range not to light or the flame to go out unexpectedly.
• Resolves intermittent ignition or no-heat symptoms related to a faulty flame sensor.

• Turn off both the gas supply and electrical power before starting work.
• Verify correct probe orientation and secure connections; do not bend or kink the sensor.
• Tighten fittings to manufacturer torque; avoid overtightening which can damage the probe.
• After installation, check gas connections for leaks and test ignition.

This burner housing is the main support for a gas cooktop's burner assembly, aligning the burner, directing the flame, and securing associated ignition parts for reliable cooking performance. Replaces a damaged or warped housing to restore proper burner operation. What it does:

• Holds and aligns the burner cap and ring so the flame burns evenly across cookware
• Centers the ignition and thermocouple components for consistent lighting
• Protects internal gas and ignition components from spills and heat damage
• Helps prevent uneven heating or unstable flame patterns caused by a warped or broken housing

• Turn off gas supply and electrical power before starting work
• Replacement typically requires removing grates, burner caps, and possibly the cooktop surface
• Inspect gaskets/seals and replace if cracked; ensure parts seat correctly for safe ignition
