Sounds more like a failure to light. Make sure you have a bottle full of gas, and it is turned on. You will also need a fully charged battery, or plugged in to shore power. After that, search the threads on here for furnace problems. Plenty of descriptions of operations, and some trouble shooting info. Sorry to direct you to a search, but there are circuit boards, various switches, ignition, and a whole sequence of events that must happen, in the correct order, before your furnace will work. Too much for me to remember.
May also get get the furnace model number and go the furnace manufacturer website, and see if they have a troubleshooting guide.
