Furnace not working first time out.

simple easy test is there is 2 wires from stat to furnace. wire goes up to stat, makes circuit on call for heat then sends back to furnace. Check for 24v from stat. You can actually wire nut those wires together to bypass stat. if you have 24 v feeding furnace it has a board or other issue in the furnace.

Has to be 12V.

Sounds good. I can't imagine it would take that long for parts on a new unit. Should be less than a week to see parts, unless it is a new model furnace. In the meantime carry a small electric/ceramic heater with you and run he A/C fan to circulate the heat. That's what I do when it gets cold! One 30 lb LP tank lasts me almost 2 years.

My original post stated the blower did not come on. Maybe if you read it carefully my information wouldn't seem so "vague".

Sorry I missed that. Good luck with your troubleshooting.

I appreciate your help. Sorry I replied back the way I did. I didn't realize how it sounded until I read it back. I just spoke to the service guy. Other than a loose wire at the thermostat or the furnace, it would require removal of the furnace to troubleshoot. Not a difficult task but it is brand new and under warranty. If I do not find a loose wire this weekend it will go back to the dealer next week. He says 4-6 weeks is typical for parts so I am hoping for the best. If it needs parts I will take the unit until the parts come in. I wouldn't want it just sitting there waiting for parts. I have trips planned for November, December and January, hopefully with a working furnace. Thanks all for your help. I'll follow up once the problem is located.

OK.....

It works as explained in prior post
RV Furnace (Suburban/Atwood) basically work the same....same type of components, same safety features, same circuit paths. Not much difference regardless of WHAT trailer they are installed in.



Turn it ON
Highest setting on t-stat (warmer)

DC goes from DC Dist Panel where the fuses are to furnace and to t-stat

When t-stat Clicks DC goes from t-stat to furnace circuit board and allows the DC from fuse to go to fan motor.

Until fan comes on NOTHING else will happen

Furnace is directly opposite the furnace vents on drivers side of trailer.

You need DC to furnace.....simple as that

What is inside that panel below fridge?
Is it the AC Circuit breakers/DC fuse Panel or is it the furnace access?
What Suburban Furnace MODEL??????

Answer question and help can be provided.

Otherwise.take it to dealer for warranty work

The trailer is in storage but I am pretty sure the furnace is behind one of two service panels below fridge and stove. I checked the fuse for the furnace at the power center and it is good. I will try your suggestions this weekend and see if I can save a warranty trip. Thanks for your help.

Sorry...It's been a long day.

I am not really asking for a diagnosis. I asked if I was missing something. Maybe a simple solution because I did not get the operation explained on the walk through. I don't want to haul it back to the dealer if I missed something simple. This is the first unit I have owned that did not have the heat blow right from the furnace cover. Maybe another owner of the Salem 261BHXL (or similar)could let me know how theirs works? Thanks again!

There's too many variables to diagnose it over the internet. And we'd need you to actually try some of the suggestions and report back what happened.

Or.....you could just take it back since it's brand new and have it repaired/replaced under warranty.

If you don't want to do that, fine. But lose the attitude. Yes, people often miss things while reading through posts. But you're the one asking for help. A little patience would be appropriate on your part. Especially if you have an easy option you refuse to take

In order to get assistance you are going to have to try things and report back. Your description of the problem is a little vague. When you turn the thermostat to heat does the fan come on?

Normal operation is turn thermostat to "ON", turn thermostat to "HEAT" set fan to "AUTO". Adjust temperature to a point where it should call for heat. After a few seconds the fan should come on but no heat will be produced. After about 30 seconds of just fan operation the furnace will ignite. It will still take several seconds before you will actually feel heat being produced as the interior of the furnace and the duct work will have to come up to temperature before warm air will come out of the ducts.

You really need to give us some clues if you want help. I don't even know what "high heat" means. Most thermostats have a numerical setting that approximates the desired temperature. Perhaps you mean you have the fan speed set to high??

My original post stated the blower did not come on. Maybe if you read it carefully my information wouldn't seem so "vague". Here is what the thermostat looks like.


There are no other visible furnace controls. The furnace is not even visible.
When I slide the lever from the off position it clicks. This does not seem to be anything but the switch clicking to the "on position". High heat meant the warmer position of the switch.
