Heater lit but blowing cold air

[Fixed_Sight_Tra]

Good Morning,
As it says the heater in my TT, an '01 Keystone Tailgator is blowing cold air. It gets used regularly as it is the office/ classroom at my shooting range. I have a solar panel which was producing so I know I had 13+ volts. I changed tanks and lit a burner to make sure gas was flowing with no problem. I recycled the T stat and went outside, heard the ignitor come on and felt warm air come out of the heater exhaust. It was warm but not as warm as usual I think. I let it run for a while but it continued to blow cold air. I have another class this am so I am going to take the front off and see if there is anything I can get to but any help is appreciated.
TIA

I might be a long shot but I had a similar situation once a few years back.

Turned out that when I filled the bottle and put it back on I somehow managed to trigger the built in shutoff in the manner I hooked it up and turned the valve on. There was flow but not much.
My solution was to disconnect the tank, hook it back up and slowly open the valve.

Worth a try I guess.

Tried this and it worked. I thought lighting a burner would do essentially the same thing but I was wrong. It still doesn't seem to be as hot as usual. I think I'll take a compressor out and blow it out and see if it has some dust built up inside.

Thanks for the advise.

Cool! Once in a while it's nice to find a simple fix.
I always do the lighting a burner thing too and one would think all is well but sometimes not.
Glad it worked.

Another thing.. Back when I was a working stiff first part of job we had a big Computer Room HEVAC system, it controlled both heat and humidity most of the time and did a very poor job of it.

Now, having some training in science and engineering And having watched Technicians work on it I knew the thing and how it worked.> But I'd turn it on cause it was a bit chilly and the others in the room would be like "WHat did you turn that on for do you know how cold it is outside?" (Uh, what does "how cold it is outside" have to do with anything?) or "It's blowing cold air... I really liked that one
I'd open the desk drawer, Take out the Thermometer and hand it to 'em
It was blowing 72 Degrees F... Exactly what it was supposed to do.

sO WHY DID THEY THINK IT WAS BLOWING COLD?

It was blowing that's why.. 72 degree air STILL, is comfortable, but blowing the way this turkey blew it felt quite cool..

Same with my furnace.. I can detect the heat when it's blowing.. But it is far easier to detect with a probe than my hand. The Dry Bulb probe is not affected by wind speed like my moist hand is.

Thanks.
I'm on my out to the range. I'll give this a try.
