Hi,
I have a water heater made by A.O. Smith model FPS that will not produce flame to heat the hot water. The pilot stays light, and the blower motor is running, but the flame will not kick in to heat the water. I had already tried vacuum all the rust and dust out of the bottom of the screen thinking it might be an issue with the air flow. But, that didn't make any difference. I took out the Thermocouple and clean it with sand paper but didn't help either. It seems like there was no gas coming out of the burner tube. Any idea what could be the problem here? Please advise. Thanks.
