Hello ok if the vent motor comes on it may not be closing the pressure switch. So look for the motor and there should be a hose connected to a pressure switch. Take it off and blow through it. Then use a paper clip to clean the ports where the hose connected. Tell me what happens after this. i will look up a spec on it. Richard

Hello several ignition or gas valves came with this model. So first take the doors off and look for the gas valve see if you can find any numbers on it. Next look to see if you have hot surface ignition or spark ( do you ever hear it spark or click) let me know and we will go from there. Richard
