Trying to get heater working on my 29hfs, not good at reading manuals. But it's 38 degrees outside and I put the Ac button on 90 and still cold inside camper. What am I doing wrong

Suggest you check to be sure you have thermostat in auto to heat mode. Check for tripped breaker? My first trip out dealer was to have lp tanks filled but didn't. Bought an electric heater to get us through the first cold night and filled the tanks, next day-no more troubles. Good luck

Here's a link to the suburban furnace troubleshooting manual in the 'Library' section of the forum... Forest River Forums - Downloads - Furnace - Suburban furnace troubleshooting

If you have the same thermostat as I have, use the mode button to click to HEAT. It has COOL, FAN, HEAT. Choose HEAT.

If your thermostat has different settings, I can't help.

I'm pretty sure it should not be on AC. I have a 2015 24 HFS and can't remember specifically when u click through the options what it should be on for heat

My Domestic thermostat / controller has an On/Off Mode switch. Pressing it steps between Fan Cool Furnace and Off. When it is stepped to Furnace use the + to raise the temp to what you want. The fan should he on Au (auto). If on Hi or Lo the furnace fan (no heat) runs with the AC. Of course you must have gas and it turned on. Test by lighting a stove burner. Tell me, does it seem to try by running the fan? Can you hear the igniter click?
