Goodman GMH95 furnace won't ignite
If you are getting voltage to the meter but no gas it is either a bad gas valve or no gas. Check you have gas supply. If it were the pressure switches you would not trigger the igniter. If it were the flame proving system it would light and then go out after 2-3 seconds. If it were the circuit board you wouldn’t get 27 volts at the gas valve. No gas or very low volume or bad gas valve. I have seen where a clogged gas pipe would give me pressure but as soon as the gas valve opens the pressure drops to nothing, restricted line.
