Goodman warm air gas furnace. Gas burner would not light.Status code light blinked continuously. Igniter glows red hot. I cleaned flame sensor with fine grade sand paper. Checked transformer line voltage 110 volts in and 26 volts out. Sufficient power to open the gas valve. Gas burner still did not light. I have not checked air filter but I will replace it anyway. Any ideas you may have concerning my dilemma will be greatly appreciated.

    What's the model number? Does the gas valve open? – Tester101 Mar 29 '15 at 13:29
  • There should be chart on the inside of the unit saying what error code the blinking represents. – Mysterfxit Sep 21 '16 at 11:56
  • Have you checked the limit switches that sit around around the burner, there can be as many as 8, also check the condesation trap to the pressure switch – user70085 Oct 20 '18 at 5:52

Try playing with the pressure switch on the inducer blower.

Test all sensors for continuity.

Verify the gas assembly control valve is still functional.

  • Verify that gas flows when the gas valve opens. Do you smell gas? – A. I. Breveleri Jan 24 '16 at 4:08
  • Can you light manually (cig lighter) near the valve? Is your stove level? Gas won't ignite if it's flowing away from the ignitor. – Wayfaring Stranger Feb 23 '16 at 19:03

I had a Goodman that had a continuous blinking light that didn't have a corresponding error code on the chart. I replaced the control board with a new one from Amazon and it fixed it.
