Saved our lives, snowed in blizzard in Missouri Breaks with my niece's trailer. Freezing and no way out, finally watched your video and unable to really see thermostat, was able to get ac mode off so my Beauties and I are okay. Gonna check roads, get these little ones home and retrieve trailer when roads are better. God bless you.

Thanks a million, we were having this dilemma

[bricecastillo]

We're out on our first outing and I was baffled why it was cold out there AC vents. Thanks so much!

[Miguel.C.A.]

Thank you a million. Do you need to have the gas switch on for it to work?

[DonJen]

I have a Alfa Wolf Travel Trailer with an electric fire place. In order for me to heat my camper, I have to turn on the fireplace which only heats up a small area. Never have I figured out how to get the hot air to blow from the ceiling vents. I dont think my travel trailer is setup that way. I maybe wrong so I give this a try and let you know. On my dometic thermostat, it does show a furnace setting but it doest blow out hot air. Only cold air. Help...

Thank u what a great fix for weak programming

[Scumproof]

Thanks i couldnt figure out why my ac was blowing at the same time my furnace was on LOL

My heater quit working in the middle of the night. We heard a pop, and didn't know it wasn't heating anymore. Got up hours later and it was 59 inside with no heat coming out. We had to switch to gas. What is the sail switch??? It hasn't worked since

[jayblack]

Ahhhh thought this might be our fix - it was on HIGH - switched to AUTO but it still just blows cold for 20 seconds then turns off. Dang.

Happened to us once before and it was a sail switch I believe!

YOU WILL NEVER GET ANY WARM AIR OUT OF THE CEILINGS VENTS UNLESS YOU HAVE A HEAT PUMP & AC COMBINATION.
NEVER
