How to Test the Ignitor in a LGR7646EQ2 Gas Dryer

The Whirlpool LGR7646EQ2 is a residential gas or electric dryer with multiple drying cycle and temperature setting options. Whirlpool LGR7646EQ2 gas dryer models contain an internal component, known as an ignitor, that lights the gas that is, in turn, used to warm the air that dries your clothing. If there's a problem with the ignitor, your gas dryer may produce little or no heat. Fortunately, you can perform a simple test to determine whether the ignitor needs to be replaced.

Things You'll Need

  • Flat-blade screwdriver
  • Needlenose pliers, optional
  • Digital multimeter

Instructions

    • 1

      Slide a flat-blade screwdriver into the space between the dryer's front and bottom toe panels. Locate the metal retaining clips approximately 4 inches in from each side of the toe panel. Use the tip of the screwdriver to apply pressure to the clips until they release. Set the removed toe panel to the side.

    • 2

      Turn the cycle control knob to the "Automatic" setting. Set the temperature selector knob to "High Heat." Press the "Start" button to begin the drying cycle.

    • 3

      Locate the burner assembly below the drum, on the left side of the dryer cabinet. Check to see if the ignitor is glowing; this indicates a properly functioning component.

    • 4

      Test the ignitor with a digital multimeter if it doesn't glow. Unplug the dryer from the wall outlet before testing to prevent serious injury.

    • 5

      Disconnect the two wires from the ignitor component. Pull firmly on the wire connectors to free them from their terminals; use needlenose pliers if necessary.

    • 6

      Turn on the digital multimeter and set it to measure RX1 resistance. Touch one multimeter lead to each of the two terminals. Make a note of the reading; ideal readings are between 50 and 600 ohms. Replace the ignitor if the multimeter registers zero or infinity.
