I have a Goodman Model # EG030075-1AB REVC Gas Heater it has been converted to run on LP Gas. Furnace has worked fine for years. Turned the heat on and nothing happens. The LED on the control board is not lit. I checked the voltage at the control board and all the voltages appear to be normal. The voltage to the gas control valve seems to be off though. I thought the valve was supposed to be supplied with 24v from the control module but it is only reading approx 4v when checked. There is no gas flow no fan no nothing happening with this unit. Where do I go from here?

Check to see if the rollout switch it tripped its in front usually between the valve and the burners just above the burners

If the LED isn't on, you likely have control power problems or perhaps a bad board. Where did you check the control voltage? Do you have 24 volts AC between the R and com terminals? If not, check the fuse on the board.
