lost my thread; dead propane heater

I have one of those sitting out in my garage even as I type. A year or
so ago I had the same problem you described. I called and they
recommended I use Mr. Heater hoses and gave me several things to try.
Try them I did but to no avail. I called back and they said send it
in. I did that, to the tune of about 20 bucks if I remember correctly.
Well, I got it back some time later and it worked just fine (with my
new Mr. Heater hoses).

Then, as the weather turned colder this year I broke it out again and
... same problem. I tried all the things in the manual etc but decided
not to invest any more time or money on it. The heater is really nice
when it works. But .....

Michael, I didn't know you could crochet an Afghani. Is that why they
don't allow crocheting needles on airplanes?

Hrm. So I'm probably in for fewer headaches in the long run if I just opt
for the sledge hammer and find some better heater instead then?

Pity. Although it never actually got my shop warm anyway. Supposed to have
enough BTUs to do the job in spades, but it never did more than toast my
ankles. Probably wouldda had to leave it on for hours to do any good, and
I was a tightwad with the gas.

Could be.

I didn't use a wire because the manual specifically said not to do that. I
did backflush it with air, and air came out the other end.

Worth a look. Thanks.

That's actually a good idea. I didn't think of that.

I did take it apart. There really is a ruby in there, with an eeeeeency
hole in it. The ruby was gunky. I polished it. That seemed to cure the
heater's woes, and I was getting ready to write up a success story, but
then it just cut off on me a bit ago.

I damn near just hurled it, cylinder and all, out into the street.

I think it's either the thermocoupler or the tip switch.

Try blowing out the pilot area with brake cleanner. It'll turn to
gas as it "dries" and will remove grease, dirt and generalised
crud.

1. maybe trash in the pilot jet. I would disconnect it from
the controller and reverse flush it with air. Maybe use a
wire to dislodge it from the orifice first, as someone else
has suggested.

2. Don't know about this machine, but some controllers have
an adjustment for the pilot. It is often underneath a screw
cover which has to be removed first. Look for a largish
screw near the pilot line.

Sounds like the pilot orfice is partly blocked/restricted. You
might try to clear it with a fine wire.
