No heat!!!! RV guy help!

[qepv25a]

We are camping in Mississippi. Temp going to 37 tonight. I put the furnace on, and the AC came on. Propane is full, Thermostat set on furnace, temp set on 72. Air starts blowing out the ducted ac. No air flow in the floor vents. Air is slightly warm from ac vents. What is going on? We have a tracer 2800rld. Thanks Bob Fears.

If your heater is clicking when you turn thermostat on you have a propane issue.

turn tank off and wait a few seconds then SLOWLY turn tank valve back on .

you may have "poped" you protection valve.

The heat is now blowing, but the AC is still running with a small amount of air is coming out of the AC vent. It is not hot, just room temp out of the AC vent. Is this normal? Thanks Bob The heat is coming out of the floor as it should.

Is your "Fan" set to "ON" or "AUTO"?

Just try this... turn the heat on if the A/C comes on go to your breaker panel and flip the breaker off to the A/C and see what happens.....Now I will tell you with a digtal t-stat if your set point of the a/c is with in two degrees of the heat set point both a/c and furnace will come on at the same time if the t-stat is set on "AUTO".

Sounds like you have the fan set to Lo. If it's set to Lo or Hi the A/C fan will run when the furnace is ON (but the A/C won't be cooling).

Set the fan to Auto and hot air will only blow from the floor vents.

The guy that designed that thermostat needs his head examined.

Maybe so QEP. An extra labeled switch for the fan wouldn't hurt, but that adds weight. (and also a few pennies). I went through the same key learning the first time we put the heat on..I was able to figure it out because my home T-Stat is similar.

Another observation btw...in the matter of the "Dometic T-Stat hidden Fan Speed Control" feature. We see this problem on this forum maybe like once a week. If not a redesign..you'd think there would at least be a hand written Post®it stuck on the wall next top the T-Stat of every FR unit coming off the line!

My learning curve on this was exactly like yours.

Easy to understand ... once you understand!

It's like getting the inside temp to display ... you can only check it in the off mode by pressing the + or the -. Why don't they have a display that all the time??!!?? The display should show current temp and depending on the mode the temp & fan setting.

My $9.00 digital travel alarm has a slightly larger display and shows me like 10 different things/settings. So honestly it shouldn't be a cost thing.
