SOURCE: reddy heater won't stay on

sounds like a Thermal Cut-off this is a small sensor that detects if the heater has ignited properly, sounds like this sensor has failed and the heater shuts off to prevent from gassing anyone

Bad flame sensor. Try to clean it with some steel wool

SOURCE: my heat n glow fireplace comes on fine with all

You may have a few sensors, one may be a thermopile that energizes the pilot. It is a very thin but long bulb located in the pilot flame. Then you may have something called a thermopile which is also located in the pilot flame that energizes the main gas valve. It is a larger diameter bulb and will have metal wrapped wireg going to the gas valve. If the pilot stays on but the flame goes out under the logs, change your thermopile and look for a bad connection at the gas valve or switch. If both the main burner and the pilot goes out you may have a gas valve problem or a plugged vent pipe. If the flame just disappears it is most likely a gas valve. If the flame changes colors and lifts from the burner, that is a sign of a plugged vent. Good luck.

SOURCE: Goodman furnace burner ignites then shuts off in about 10 seconds

if you have replaced the flame sensor and it will not stay lit, the draft safety switch may be opening. It works on positive and negative pressure created by the inducer fan motor.You may have a restriction in your heat exchanger or if is a high efficiency furnace, it may not have the drain tube installed properly with a trap. The trap works just like the trap under your sink and if water isnt in the trap, the pressures can be effected enough to open the draft switch(some call it an air pressure switch)

I have two 7 month old Pro Com vent free gas garage heater ( Model Number MD300 TGA Propanr heaters. I use them for emergency heat during power outages in my greenhouses. Last year they worked perfectly...

Are all three now connected to the same source? That might have something to do with it. Anyway a safe and easy solution is to flush the pilot assembly with Rustbuster and allow it to dry . This clears the pilot of dust and cobwebs without disturbing the innards of the vent free safety pilot. Muck that uo and you will have to buy another. Get yourself some rust buster.

LLG325N Larrs heater wont stay running. Replaced the pilot assembly. It fired up for about 10 seconds and then quit.

You should have a flame sensor wire going to your pilot. Make sure that it is hooked up correctly. If the sensor isn't relaying flame to the control box it will think you don't have a flame and will shut off gas flow for safty reasons. So be sure the wire is connected and in good shape. I hope this helps.
