Vent free wall mounted LP heater

[Streetbu]

So I'm having issues with my heater. Was working fine, then suddenly it shut off, pilot and everything. Figured the thermocouple went bad, so I just installed a new one 20 minutes ago. Same issue. Obviously that wasn't the problem. Only thing I can figure is the valve assembly has failed and it thinks there isn't enough oxygen so it's shutting itself off. Mind you, this has been installed and working fine for the last 6 or 7 years. Nothing has changed. Any bright idea's?

Make and model would help us help you.

I had to clean the pilot sensor this fall to keep the flame going and I cleaned out the oriface in the pilot, damn spiders were laying eggs inside during the summer.
Open up the unit, fire up the compressor and blow everything out. Clean the sensor, and using a small bristle brush clean the tubes.

Glo-Warm blue flame wall mount heater. I believe it's the 15k btu model. Don't really want to unbolt it from the wall to get the actual model number. The pilot sensor is the thermocouple so unless the new one is bad out of the box that's not the problem. It also worked fine since we fired it up in September. This problem just started last week.

Trash in the LP tank or line??

Same tank we've been using, matter of fact, same tank that has been hooked up for the last few weeks and it was working fine. We're not out, hot water and stove still work fine, tank is about half full.

you must be the worlds luckiest sob to get 6 years out of a wall heater. they last 2 years on avg here 3 if im super lucky before they **** the bed and i have to get a new one. there so cheap i feel better with a new one hanging on the wall any way.

Take air comp or air tank and blow the dust out of the pilot and nozzle assembly. The thermal couple was fine.

The only thing left in it is the control knob assembly. I wont replace that, I'd buy a new heater first. Just surprised that would've failed and thought I'd ask here first.

That was going to be myy next step, but didnt have much faith it would fix it...

I have one in my office for 20 yrs and another in a house for 15. The one in the house needs to be blown out on occasion. It fails to start like the one the OP has. Gets a little flake of sheet in it one may not even see and they are fussy, rightly so.
I blow the screens off lightly before season. Never replaced a part on one.

Its hard to remember its so simple.

Wow, you guys nailed it as usual. Blew it out, immediately noticed a difference in the color of the flame. Seems to be working great so far. I think we got it! Thanks again!

LOL! Wish all the fixes were that easy!

I know! Of course the wife was giving me a hard time, "didn't I tell you that yesterday? " Yes dear... LOL
