    Why won't the convection fan operate in my Jade Range?
    • E
      eparkerSep 12, 2025
      If the convection fan in your Jade Range will not operate, here are some potential causes: * A failed door switch; perform a door switch test and replace it. * A failed blower AUTO/MANUAL switch; perform a blower switch test and replace it. * A failed motor; perform a motor test and replace it. * A wire short; use a wiring diagram to test for shorts in the motor circuit. * A failed capacitor; replace the capacitor as needed.

    What to do if the top burner on my Jade Range will not light?
    • P
      petersonrobynAug 23, 2025
      If the top burner of your Jade Range won't light, it could be due to several reasons: * The orifice might be the wrong size for the gas type, so verify the orifice size and replace it if needed. * The gas-to-air ratio might be incorrect, requiring an air shutter adjustment. * There might be a blockage in the vent of the pressure regulator; clear any obstructions or replace the regulator. * The pilot might be positioned incorrectly, needing adjustment to intersect the burner ports. * There could be an obstruction in the air shutter or venturi; clear any obstructions. * Water or grease might be in the burner ports, requiring cleaning. * The pilot flame might be too big or too small, needing adjustment to intersect the burner ports.

    Why is the griddle on my Jade Range not achieving the correct temperature?
    • M
      michellesandersAug 27, 2025
      If the griddle on your Jade Range isn't reaching the desired temperature, consider these potential causes: * The thermostat might be out of calibration; calibrate it. * The gas pressure might be low; perform a gas pressure check. * The orifice might be incorrect; verify the orifice size and replace it with the correct one. * The thermostat sensor might not be in the correct position; verify it's out of the factory position and affix it correctly. * The flame might be hitting the thermostat sensor; move the sensor to the correct position and check it for flame damage. * The gas-to-air ratio might be incorrect; perform an air shutter adjustment. * The burner might be obstructed; clean all burners.

    • J
      Jason ShawAug 28, 2025
      If the oven in your Jade Range is slow to heat, there could be several reasons: * The orifice might be wrong; verify the orifice size for the gas type and replace it if needed. * The gas pressure might be low; test for gas pressure and supply pipe sizes. * The vent in the pressure regulator might be blocked; clear obstructions from the pressure regulator or replace it. * The oven door might not be closing properly; check the oven door for obstruction or align the door.

    Why are the burners on my Jade Range not working well (flame is lazy or yellow)?
    • H
      hurleyemilyAug 29, 2025
      If the burners on your Jade Range aren't working well, producing a lazy or yellow flame, it could be due to: * An orifice that is too large; verify the orifice size for the gas type and replace it. * An air shutter closed too much; perform an air shutter adjustment. * Gas pressure that is too high; perform a gas pressure check. * Grease, water, or debris in the burner or deteriorated burner ports; clean all burner ports or replace burners. * Foil on the burner hanger; remove the foil.
