I have A Goodman furnace that will not ignite. The LED on the control board is stead on (indicating normal operation -- no flashes). When set up the thermostat, a call for heat seems clicking, then inducer fan is on, then seems gas is hissing for a few seconds. But the hot surface ignitor (HSI) will not turn or grow red, and the furnace will not ignite. Any ideas?

I will replace the control board, and check if the voltage to the HSI.

I would hold off on the control board. Check for voltage to igniter first. If your getting power to it and it isn't glowing, then the igniter is bad.

Thanks so much for your advice! I checked voltage to the igniter and it has 120 VAC. No continuity on the igniter. Therefore, the HSI is broken. The control board is OK.

It took three days for me to order the HSI from Ebay. I could not purchase one from local stores as these stores only sell to HVAC contractors.

10 minutes work to change the HSI, and the furnace works fine. Saved hundreds $

I also cleaned the flame sensor while I change the HSI.
