    Why are the burner flames very large and yellow on my NXR hob?
    • A
      Amanda BarryAug 14, 2025
      If your NXR hob's burner flames are very large and yellow, it could be due to clogged burner bezel ports, improperly positioned burner ports or caps, using the wrong type of gas, or a faulty regulator. Try cleaning the burner bezel ring ports with a straightened paper clip, needle, or wire. Also, remove and carefully reinstall the burner bezel and caps. Ensure that the type of rangetop matches the natural gas supply. Check the installation, replace the regulator, or set the regulator for the proper gas.

      Adam RamosAug 17, 2025
      If the top burners of your NXR hob do not light or burn evenly, ensure the unit is properly connected to the power supply. The issue could stem from the plug not being completely inserted or clogged burner holes. Remove the burner heads and clean them. Also, check the electrode area for any burned-on food or grease.

      If your NXR hob is sparking but there is no flame ignition, check if the gas shut-off valve is in the ‘OFF’ position. If it is, turn the shut-off valve to the ‘ON’ position.

      If the igniters on your NXR hob spark continuously after flame ignition, it could be due to reversed power supply polarity or wet/dirty igniters. Have the polarity corrected, and dry or clean the igniters.

      If nothing works on your NXR hob, the rangetop might not be connected to the electrical power or the power supply is not energized. Have a qualified electrician connect the rangetop to a properly sized electrical power supply and check the power supply, including the house circuit breaker, wiring, and fuses.

    Why does the burner flame go out at low setting on my NXR hob?
    • G
      Gail RodriguezSep 1, 2025
      If the burner flame goes out at a low setting on your NXR hob, it could be due to low gas supply pressure or obstructed air intake holes around the knobs. Contact your gas company to check the gas supply pressure and remove any obstructions around the air intake holes.

    • A
      Amy HughesSep 8, 2025
      The 'cracking' or 'popping' sound you hear from your NXR hob is the sound of metal heating and cooling. This is normal.
