I have a Mr Heater infra red propane heater that won't stay lit. It will stay lit for an hour or two then the pilot lit goes out. I have no problem getting it turned back on but at night I can't depend on it to stay on and keep my shop warm.
Your pilot flame should be blue with a small yellow tip, and it should cover the thermocouple (a small rod in front of the pilot light). If the flame is too small and doesn't cover the thermocouple, it may be adjusted too low, or you have low gas pressure or you have a leak in your gas line coming in to the heater. If the flame looks like a lazy yellow flame, you are probably not getting enough air to the flame. Check that your air openings around the pilot are not clogged up. If the flame looks like a waving blue flame then you probably have excessive draft at the pilot. If the pilot flame looks good and covers the thermocouple, then the thermocouple might be bad. Best of luck. I hope I have helped.

The thermocouple connection had to be tightened securely. i found out that it is an electrical connnection.

Hi,
I,d suggest that you have either a case seal Damaged, allowing air into the casing.
Also possible fault may lie within the Flue air pressure Valve/Switch If applicable.
The heater/Boiler will have certain conditions to meet.
The Fan/flue switch ( Pressure switch. Will be designed to speed up the fan, before firing the main Burner.
As for the Noises, i,d suggest that the boiler is whats commonly known or reffered to As Kettling. Which usually indicates Overheating. This would cause the main-burner to distinguish as a fail safe.
Recommendations:- De-scale the heater, with a commercial descaler. Thoroughly flush the System. Then re-fill with required Amount Of Commisioning Fluid. i.e Fernox Or Sentinel et,c.
Also get the Fan/flue checked out for correct running speeds.

sounds like the thermocouple is going out this is the part the flame from the pilot burns on and tells the gas valve to stay open by producing a small amount of electrical current in milli-amps these can be purchased @ a good hardware store and you must position as it is when it comes out , and must be the same length , make sure to connect to gas valve clean and tight , also is there a moisture trap in the line if so you might need to turn off gas and make sure it is free of moisture , this is a good place to start with these items

Hi Cindy,
It seems that your heater is not sensing the flame is lit and is shutting gas supply off. There should be what is called a flame sensor, it is a thin pc. of metal that sticks out into where the flame when lit.
This usually gets charred and dirty, if you unscrew it and clean it with a soft cloth then re-insert it, it will get you by. You should get a new sensor when you have a chance.
Good luck and be sure to disconnect from any power source or turn unit completely off when orking on it.
Thanks,
Paul

On your thermostat - R is the power in terminal. Y is the cooling out. W is the heating out. (G is fan out). It does not matter which wire goes to R, the other should go to W - if no heat with a call, the thermostat is bad.
