heater question

I've read thru the link that John sent and will test a couple of the tips in there:
- test the LP pressure  (we were at 9,800 feet and low temp was ~30F when it decided to act up)
- check wire connections on the limit switch (it sounds like it should re-set itself so not sure I can test it)
- run it tonight to see how hot it is getting in the compartment where it sits (not sure how)
- verify that it is really hitting the set temp when it turns off

If none of this tells me anything, I'll start replacing parts, starting with the thermostat.  I'll post what what I find out.

Was able to test the thermostat, it is working fine. Also was able to check the temp in the heater compartment while it was running.  97 degrees with room temp at 72.  Did a little more research and found out that the heater is going into "lockout".

Possible issues:
- regulator
- contaminants in the fuel
- leaking vent pipe
- bad micro switch

LP Fuel and regulator seem like good places to start so will borrow a tank next weekend to check the fuel.  Will get some high temp silicon on the vent pipe to be safe (not sure how to test this).  Will check the micro switch and all connections when it is opened up to get at the vent pipe.

Stay tuned...

Oh, I should have typed +30 not ~30 (tilde).  ~30 and -30 do look alike.   Temps actually got down to about 33... which is too cold for my taste.  I think I would have headed home if it was -30.  I don't like cold temps, the Pod did keep us warm ... I just had to get up 2 or 3 times to reset things.

This one I purchased is a Road Pro model. I looked and it is available on Amazon also. When I have it running, it is usually on the low setting. That is adequate to circulate the air.

You might also want to check and see how the furnace was mounted. I saw that whoever installed the furnace in my R-Pod did not use the furnace's mounting holes, but instead punched new ones that meant that the furnace was not quite in the location for which it was designed. It also was not quite square with the face. I moved it and used the correct mounting holes while squaring it with the face. It meant that the cover plate also fit better.

I don't think you need to make holes in the cabinet. There is an air return, and the gaps around the sides of the faceplate are also cold air returns. It is designed so that cold air is pulled in around the perimeter of the housing to the back of the unit where the fan then blows it through the center heat exchanger part to be pushed out through the grill. The separate square grill face is also a return. It is easy to see if you take the faceplate off. I'll try to get a couple of pictures in the next day or so to illustrate what I have described.
