Wall mount propane heater ignites, but won't stay lit

I have a 10,000 BTU Wall Mount Reddy Heater in my fish house. The pilot light will ignite and stay on. When I try to turn up the heat, it will come on momentarily and then go out and blow out the pilot at the same time.

    I also have a wall mounted LP Reddy Heater installed in my garage. The pilot light will stay on; but when turned up the heater runs for 10 to 25 seconds and turns off completely. I have tried opening windows to increase air flow, taken it apart and cleaned it, and had the LP company confirm the gas valve outside the house is functioning properly.

    Any other ideas?

I have a Reddyheat IWH16NLTD with this problem. When the heater fan turns on it blows the pilot light slightly up and away from the thermocouple causing the safety valve to close after the ceramic cools down. The manual says that low gas line pressure can cause the flame to rise too far from the thermocouple causing this problem, so either it is a problem with gas pressure, or it is an assembly plant problem.

SOURCE: Torpedo heater wont stay lit.

Do you have the serial number or the manufacture date? There are some design changes and I would need to know the year of manufacture to assist accurately. Usually it is a relay or the thermocouple connection that will affect the unit staying lit.

SOURCE: The pilot light will not stay lit, I was told

Hi, this heater doesn't have a thermocouple, it uses a pilot generator which is more reliable so I doubt you need to change it out. First thing to check is that you have a clean "sharp" blue pilot, you should be able to hear it quietly roar. If it is yellow and appears "soft", the pilot need to be cleaned. The easiest way is to use a straw or tubing of some sort to blow into the pilot, gently tapping the pilot assembly. That should clean it up and heat the pilot generator properly. Tighten the the screw terminals at the control valve to assure good electrical connections and last but not least turn off the thermostat until you get a standing pilot. Good luck and stay warm.

SOURCE: warm morning propane heater. new thermal couple.

There are basically three things that can go wrong with the Warm Morning .
Sensor shut off. There is a sensor button on the back of the unit with a wire going from it to the thermocouple. This sensor turns the heater off if the flue is blocked, however it will also shut the heater off if the wire contacts are dirty, or if the sensor has gone bad.
You can test this by bypassing the sensor. Disconnect the two wires from the sensor and reconnect them directly together. If the pilot stays on, your problem is here. Try cleaning the wire contacts first.
Pilot orifice. If the pilot flame is small and doesnt look healthy, the pilot orifice may need cleaning. The hole is very small and can get dirty. Disconnect the silver tube and clean with electrical parts cleaner. Never try to clean the hole with an object like a pin, you may damage it. You may have to slide out the burner unit to get at the silver tube. (Always shut off gas before disconnecting lines and after you reassemble, spray joints with soapywater and look for small bubbles which may indicate a gas leak. Dont use parts cleaner around an open flame.)

Thermocouple can go bad but this is not as common as the first two problems.

Pilot won't stay on

Burners don't have anything to do with the problem of pilot not lighting. Is the problem that flame will not 'stay' lit? Or you can't even get a flame to ignite? If former: possible bad pilot generator or bad gas valve. If latter, possible bad gas valve or no fuel to ignite.

Have a Reddy Heater RCP275 propane gas heater. If able to light - the heater will burn for 1-5 min. but then goes out. Sometimes burner will not light at all when the red pilot button is released. At times...

Sounds like the igniter needs to be replaced. It is normal for a heater to run five or so minutes that means the thermostat is working. then restart when the temp calls for heat but if the igniter does not work it will not light up again.

Propane heater wont stay running

is the sensor for the thermocouple located in the right spot in the flame,remove it and if you have access to a propane torch,heat the end till its red hot and leave it connected to the gas valve,then start the unit and this will tell you if the sensor is properly positioned in the pilot flame on the unit itself,if not you could have a defective new thermocouple or another safety device keeping it from staying lit or the gas valve is faulty

Won't stay lit..

I contacted and talked with their support department (866-883-9312). They instantly stated "your thermal coupler is bad". They had 1 in stock for 19.99 + shipping. I ordered it and plan to have it installed and tested by next weekend. The model I have is Reddy Heater Propane 35k to 55k (RLP55V).

Forced air propane heater won't stay lit

two items come into play here - 1) the hot surface cutout and 2) the flame detect Cd cell. Check alignment of the Cd cell or just replace it. The hot surface cutout has two terminals that plug into the two tabs on the millivolt generator.
