Question Allegro Bus heat issue

Any ideas on what is wrong? Front furnace in Tiffin Allegro Bus heats up (I can feel the heat at the exhaust port) but auto blower never comes on and if I turn the blower to "on" it comes on but no heat comes out.

Hi Jamesds,
I see you are new to the forum. Not being a Tiffin owner, I can't shed much light on your problem.
I would however suggest you give your post a title like "no heat in my Allegro Bus" or something to that effect . This will attract more attention than your handle.
Also, you may try posting in the Tiffin Forum to get folks that are familiar with your coach.

Welcome to irv2. I've moved your post to the Tiffin section to get some owner input. Good luck.

Most LP gas furnaces in an RV starts up in the following sequence: thermostat calls for heat. Fan comes on, moving air pushes a sail switch that then allows ignition to start. Since yours doesn't seem to follow that sequence, I would guess perhaps your heat vents inside the RV are blocked or shut. Closing a few vents can so impede air flow that the sail switch won't allow furnace to fire. The fact that the exhaust is hot, and no heat inside again points to blocked air flow. If you use Google to search for your make and model of furnace, followed by the word 'manual' you'll probably find troubleshooting and ideas of what to do.

Check the vent hose it slips on the output of the heater and there is a screw run thru the end of the hose into the output vent of the heater to hold the hose on, find the heater on the outsidw, locate it on the inside, pull a drawer or cbinet open you will feel the heat, mine heated up the silverware drawer
And the knives were too hot to hold.... good luck...

What year is your Bus? Most late model Allegro Buses are equiped with Aqua Hot which is a bit more complicated than a propane furnace.

If you have Aqua Hot, I suggest you give them (or Tiffin Service) a call a find a service technician near you.

If you have propane furnaces, I would agree that a hose is disconnected somewhere.
