Dryer displays E16, may run but gas burner does not ignite (gas models)

Safety first: Turn off gas supply and unplug the dryer before servicing. Gas leaks and ignition components can be hazardous.

Step-by-step checks:

• Verify gas supply: Ensure the gas shutoff valve to the dryer is fully open. Check that other gas appliances in the home are working properly.
• Observe ignition sequence: With panels in place but front access open (if possible), restore power and gas. Start a heat cycle and watch through the burner inspection port. You should see the igniter glow, then hear a click and see flame. If not, note what step fails.
• Test igniter: Unplug the dryer and access the burner assembly. Measure igniter resistance; an open circuit indicates a bad igniter that must be replaced.
• Gas valve coils: If the igniter glows but the flame does not light, test or replace the gas valve coils. Coils often fail intermittently when hot.
• Flame sensor: Clean the flame sensor with fine steel wool and test for continuity when cool. Replace if defective.

When to call a technician: If you smell gas, cannot identify the failed component, or are not comfortable working with gas, contact a qualified gas appliance technician immediately.
