Upon Arrival found that everything was in sequence of operation but the gas valve was not turning on. Found 24 volts going to gas valve but no ignition. Beat on gas valve a few times to get it to unstick and it turned on. While furnace was not running found hot surface igniter with burnt off silicone and whiting. Will follow back up to install new gas valve once it comes in and also install new hot surface igniter. Due to the situation we will contact the realtor for access to home considering they are putting it on the market. Refer to picture for realtors number. Any questions please call Brandon 602-736-3077
