coleman furnace

I have a '96 Coleman Sun Valley with a furnace, and have no idea how to operate the thing.  Can anyone help?  I have the owners manual but there is no discussion of the furnace.

Thanks,
Steve

Hey Steve,
You might want to post the make and model of your furnace so others with similar/same equipment can chime in.

My furnace is much newer but your's may operate similar:

All I have to do is
1) Slide the on/off switch to the on position which is located at the top of the thermostat.
2) Increase the thermostat temperature setting...voila....that's it.

My furnace does not have a pilot light to take care of. There is a process before the burner actually lights but the fan comes on right away. The heat typically follows shortly thereafter.

Hope this gets you started. I'm sure there's better info coming.

take the cover off the furnace and flip any switch to ON, replace cover
switch the thermostat to ON
move the temp control higher

That is how the ?Atwood? furnace in my 1999 Coleman camper works.  Many people don't know that there is a small rocker switch behind the inside cover of the furnace.  I keep mine in the off position so the furnace can not get turned on accidentally.

For the life of me I can't find the thermostat.  The furnace is the factory installed unit in a 1996 Coleman Sun Valley camper.  Any help would be greatly appreciated.

You might want to post a photo of the exterior and of the interior, behind the metal grille.

Here is a picture of the thermostat that are in Fleetwood/Coleman PUPs. Just serach along the base of the PUP at the same height of the furnace.

Hope this helps.

We have a similar thermostat and our on/off switch is on the bottom. It's just a tiny thing and it's hard to turn ours to the "On" position.

I've identified the furnace as an Atwood Hydro Flame.  I also located the thermostat.  Well, I plugged the trailer in to the electrical outlet and check to make sure the lights, etc. worked.  I then turned the gas on and set the thermostat to 90 F before flipping the off/on switch on the front of the furnace.  Nothing...no ignition and the blower didn't come on.  Can't for the life of me find a place to light a pilot.  You guys are great, and any more advice would be most appreciated.

A Google search for "Atwood Hydro Flame" turned up a group of references, including this one:

You might need to more precisely id the unit you have, but it looks pretty simple.  You also may need to locate the power switch on the thermostat.  As mentioned, it may be on top or on bottom of the thermostat, will just be a small "slider" switch, and may be difficult to move to the on position.

Hope that helps.

Sounds like no power, once turned on (thermostat and front of furnace) and the thermostat set high enough the blower starts to run. Use a volt meter to determine if you getting power to the thermostat, two wires on back.

See page 28 for troubleshooting and page 16 for sequence of operation.

No pilot, it lights its self.

That link that Chip gave you has the right info........

Note......this furnace has an electric ignition. There is NO pilot light.

The switch on the thermostat must be turned to "ON" also.

Thanks to all of you for the good advice!  Turns out it was a loose wire.  

Merry Christmas and happy holidays to all!

Good find........glad you got it working and thanks for letting us know. 90% of the time, it's something simple like that. Finding it..........not so simple.

It's kinda like the old story where a commercial building lost power to all of their air conditioning. Several contractors came out and after hours of labor, couldn't find the problem but left them with a $500 bill for trouble shooting. The last guy came out, walked over to a circuit panel, opened the door, tightened one screw and voila....the A/C was working.

Job took 30 minutes and he left a bill for $800. The building Superintendent called the guy and said, "Hey....why $800 for tightening one screw?". The technician answered, "Oh......it was only $50 for tightening the screw.......it was $750 for knowing which screw to tighten"...
