Re: Will not stay lit.

I had the same problem with my RMC-8001SS heater, After about 7-8 minutes the pilot flame would start to sputter and go out. Try this test; Use a flashlight to look through the lower front grate, on the right side. There is a thin silver metal strip on the side of the brass pilot flame orifice. It is fastened with a screw on the top and is free on the bottom where it covers a hole in the brass tube. Get a long enough thin screw driver that you can put through the grate and touch the silver metal strip. Now, remove the screw driver and light the heater. Wait until the pilot flame starts to sputter, then using the thin screw driver, put a little pressure on the lower end of the silver metal strip. The pilot flame should instantly normalize. If it does, then this is your fix....
Remove 4 screws in bottom of unit and remove the center metal plate. The metal back of the heater can now be pulled out and up. There are two metal tabs at the top under the handle. Work the back piece a bit and the tabs will come apart, allowing you access to the inside of the heater. Hold the end of the brass pilot flame tube with a 7/16" wrench and remove the gas line with a 1/2". Take out the 2 screws under the plate that holds the pilot tube and thermo-couple. Now you can get at the silver metal strip on the pilot orifice. Remove the small screw holding the silver strip. Next, gently bend the strip to put a little downward bow into it. When you put it back on and tighten the screw, this will apply more pressure to cover the hole in the brass tube. Re-assemble the unit and it should work fine. I'm happy to have my heater working again!

Re: Will not stay lit.

Sounds like you have a blockage to the main jet. If you have a compressor just blow the jet out from the top and with a bit of luck it will clear it. If not you may need to remove the outer covering and find the pipe to the main jet and again using compressed air just blow it out. Usually not much goes wrong with these apart from blockages every now and then and most of the servicing places just blow them out with compressed air. Just make sure if you remove a pipe you tighten the pipe up properly when re-fitting it. Hope this helps

Why does flame sputter and doesn't stay lit?

Either a lot of air in the lines, or the wrong pressure regulator is installed.

When I press down and turn the know the pilot lights but as soon as you let up on the knob to turn it there is a click and the pilot light goes out.. This is on my Mr. Heater Big Buddy

When the pilot lights continue holding the button down for a full minute and then release. It should stay lit then to allow you to turn it to the on position. If the pilot will not stay lit after holding it for the full minute, then the thermocouple will need to be replaced.
Hope this helps.

Cannot get my pilot to stay lit

Make sure the thermocoupler is about 1/4 in in the flame of pilot. If it persists, as you say it is, the thermocoupler is defefective. It's that bulb in the pilot flame. Good Luck, Ned

Wont stay lit

go to this site www dot desatech dot com. Here you'll find parts to repair your heater. a propane heater uses a millivolt generator to sense the flame. along it's cappilary are two push on spde connectors. these connect to the high limit temperature sensor which is mounted on the flame backplate of your heater. to see if it is the high limit shutting down your heater, jumper across the two spade connectors. if the heater stays on, this is your problem. if the flame still goes out, then the millivolt generator is shot.
