I have an SR400HD heater that fires up starts heating but stops after about 30 secs. It will cycle again, start to heat and do the same thing over and over. The only thing i notice different is a stronger smell of Natural Gas than usual. In the past when it was heating properly, I dont remember that strong of smell. Any Help be appreciated. We did change the thermistor on outgoing vent but that didnt work. Thanks , Jack

This was the problem. I had squirrels over the spring use this as a chew toy and a couple pieces of tape fixed it. I will buy new part and replace it. Thanks for help
