I have a Ruud Silhouette II Gas Furnace. The whole unit is turned off/on by a light like switch.
The AC is working, but the heater is not. It appears that no gas is flowing to the burner.
The PWR light is on, steady. The OK light is flashing; three times on, then off.
The Flame light is off in the Circuit Board.
The thermotast is not doing anything. Not sending any signal at all.
Any suggestion... anybody?
George.
