Hi my name is Robert.....

What is the make and model of the furnace? When you turn the thermostat on and raise the temp do you hear anything at all? Does the fan come on or do you hear a click at the thermostat or furnace?

Hi, don't see a name on the furnace but the thermostat is a dometic. there is no clicking. I also switched over gas bottles. Looked in the furnace area and there is a red light blinking. tried shutting it off and starting it again, still nothing. Mike

That red blinking light could be coming from the circuit board for the furnace, if that is the circuit board unplug the connector and then plug it back in and tell me what happens, normally there will be a sticker on the fan motor housing with the make and model of the furnace, some RV'S will have an outside access panel and some will not, they just have an intake/exhaust port. IF you have just the exhaust port it will be harder to troubleshoot. How many times if the red light blinking?

Basically as soon as you turn the thermostat ON and raise the temp the T-stat will send a signal down to the circuit board and the fan should kick ON, if the fan is not kicking on then it could be an issue with the T-stat, circuit board for the furnace or blower motor. Being a 2015 I might have it looked at under warranty OR if you remove the circuit board I would have a RV shop/store check it to make sure it is not the problem. Most shops/stores will have a special board tester for these, also some furnace will have an on/off switch or circuit breaker near the motor housing......
