Bosch Cooktop NGMP677UC 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.

If your cooktop has weak or uneven flames, this gas pressure regulator controls inlet pressure for consistent burner performance. Moderate DIY repair.
