Got in our 1991 Hi Lo to test the heater baecause this is the first cold day so far. Fan kicks on, blows fine, just no warm air. Gas is on. Took seat cushion panel off and can see heater, but there does not seem to be a way to check the igniter. Any suggestions?

Check out the manual for your make and model of furnace. I believe some may have a troubleshooting chart.

There is a switch on the furnace itself under the cover and also one on the bottom of the thermostat. Seems like mine will blow but not ignite if the one on the furnace is off.
Of course the manual would say. I poked around for an hour or two before I resorted to that. LOL.

Be sure the Stove works ans water heater works in the gas mode first so you know the gas is getting into the gas system. If those do not work it would be a regulator issue most likely. Just a thought! Skyking.

Thanks for the ideas. The only manual on the forum for my model is an install manual, but the effort yeilded good results. Upon looking for the potential of a switch on the unit itself, I found that the ductwork for the forward part of the trailer was installed on the end panel and with the help of my camera phone under the duct discovered the startup and shutdown procedures stamped on the end panel.

Got it going and heating well.
