lol.. get some pics of this setup and ill have a better idea..

 

Not sure why, but I could only upload two of the pics I took. I didn't take it apart yet, -using plan B. I have a Kerosene heater going, it's taking the nip out the air, but that's about it.





Doing some other stuff, I'll get to it, I need it lol.

 

Replace the thermocouple and that will fix it. Any universal one will work about 5-10 bucks.

 

its not hooked up to the propane thats why!

 

if it has a thermocouple there is no flame sensor. it is the flame sensor. reads in milivolts. other wise it has a electrode/ sparker. clean those with steel wool without chemical on it here you go http://www.cart32hosting.com/estore/...pid=159&page=1

 

try the thermocouple, we burn through a lot of those and the ignitor itself at work because we work in a very wet environment... everythings a target for the guy with the hose.

 

oops

 

Thanks for the reply's!

I wimped out and purchased a new propane heater, - that I have to return lol. Damn thing doesn't work on high , but it gets it up to 60 degrees out their within about an hour, if I use the kerosene heater to assist, that's just on the medium setting.

What I couldn't understand is that I by-passed the thermocouple, -totally disconnected and it worked for awhile ?? Maybe that just left the check valve open for a time which eventually may have shut without away to reopen disconnected..? I'll get a thermocouple for it. I still want to fix that one.

Correction, I didn't by-pass the thermocouple, I by-passed the sensor.

 

That's it, -exactly! Part of it. Then what is the deal that connects to that ? Look to the top of picture two, theres like a sensor their. Suppose I should try to find one of those as well. There's two wires running from that to the thermocouple.

 

steel wool or 220 grit will work .. dont go go crazy just a few swipes should do it. that looks like the flame sensor in the top of the pic take some steel wool or 220 grit to that. a good thermocouple should read around 25 milivolts

 

Yea that turned a couple shades of purple lol. Not sure if that's normal, - it might be, never noticed that before. Thanks for the milivolt number, I'll check that.

I guess it's worth fixing, I priced a 40 thousand btu like that one, -it's twice what I would pay for parts to fix it, so far lol.

 

for future reference dont use sand paper to clean flame sensors. The glue will interact with the sensor when it is glowing hot and can foul up the signal, which should be 1-6 microamps dc.

 

I am perty sure that since you have a thermocouple there wont be a flame sensor. That round thing at the top is a thermodisc limit switch, it prevents overheating

 

Yea, I'm thinking that's burned out, it doesn't look right. I tried to wire wheel the thermocouple to clean it up a bit, that didn't help.

Now that I think about it, I recall last year (last winter) it started acting goofy and I shut it down. The inside and outside shell was glowing red. I let it cool, fired it back up and it worked fine until now. I'll replace both, if I can find that switch.
