Goodman furnace won't light
 
I have a Goodman gas furnace Model GMP075-3. Electric Ignite. Went to turn it on for the first time this year. When setting temp on the thermostat, you can hear it click, but no fire. Followed instructions on door to turn off all electricity to it, turn gas off, wait 5 minutes, turn gas back on, turn all electricity back on it. Still won't light. The only thing I hear is a humming noise from the unit itself. Checked gas control knob, it is showing it is on. There is no fire, no glow, nothing. It clicks once and then hums.

If it is an outdoor unit check the air flow tube famous getting stopped up with mud dobbers. Will never start if airflow cannot be achieved. If indoor unit let me know and I will try and help you out?

Thanks. We did do that. Come to find out, the vent inducer fan was locked up with rust. Figured this out after 5 days with no heat :) Started manually spinning the fan and felt it tug and then started moving freely. It is working now. A little noisy because of the rust, but it's working. Thanks for the info.

You might want to get a backup motor just incase this motor decides to stop for good on the coldest night off the year.
