I had similar problems with a older Reddy Heater. I bought a 0-15 lb. gauge and removed a plug on the control end of the heater. Turn on or plug it in and set the fuel line pressure as listed on the data sheet (also listed on the heater).

IMPORTANT. This type of heater will not light if the oxygen level is below safe limits. You need more that 14% to support life. Normal is 21%.

Check your propane tanks (are they full?), make sure the valve is on, then check to make sure gas is making its way to the hot water tank, if the pilot lights but won't stay lit your flame sensor is faulty.

Bradford White gas power vent water heater; just replaced power vent motor and fan assembly because a bearing went out. Now the new fan motor runs constantly without igniting. Is there a switch that...


Some how you have disconnected the sensor that tells the main burner that the fan is on. Its trying to light but cant. On some models there is a air pressure switch that reads the pressure inside the vent pipe itself. It will have a small hose on it and if that has cracked or was not replaced it wont light. This is how its supposed to work--- vent fan comes on,sensor confirms fan is on,hot surface ignighter starts to glow red,and main burner is opened,another sensor confirms that main burner is lit,then hot surface ignighter turns off. Hope this helps.

Reliant 501 Natural Gas won't stay lit


Reliance water heater?
Thermocouple is good if the pilot stays lit continuously.

501 is older model. Unknown if this unit has FVIR protection and sealed combustion chamber or open air intake on front of unit.
http://waterheatertimer.org/pdf/Reliance-2006-Service-Handbook.pdf

With FVIR protection:
Get more fresh air to the unit.
Clean the flame arrestor screen.
Test and replace the thermocouple:
http://waterheatertimer.org/How-to-test-water-heater-thermocouple.html
Inspect and clean burner and combustion parts
Test gas pressure, bleed air out of gas line.
Replace gas control valve.
Test draft air by lighting match and see if smoke is pulled into the vent pipe at draft hood on top of tank.

The pilot won't stay lit on gas hot water tank.


Make sure thermocouple tip is seated inside the burner flame.
Make sure thermocouple is not overtightened. Finger-tight + 1/4 turn.
If the pilot lights, then ECO energy cut off is not tripped, but gas control valve might be bad.
Check color of pilot flame: it should be strong and clear blue.
If pilot flame is weak, or color of flame is yellow-orange: Clean pilot orifice and burner and combustion parts on yearly basis.
Clean air intake screen if applicable.
Increase air supply to water heater. Open a window and see what happens.
Check for adequate draft going up chimney using match under vent hood to see if smoke drafts immediately upwards.
Bleed air out of gas line.
Check gas pressure.

I have an old whirlpool gas water heater and the pilot will not stay lit.


Suspects include bad thermocouple, thermocouple slipped down and not in pilot flame, dirty combustion parts and pilot tube, dirty air intake, backdraft caused by other vent fans pulling air down water heater vent, water dripping down vent because of poor venting, air in gas line, low gas pressure, bad gas control valve, hot attic environment, tight house not allowing enough air:

Replace thermocouple:

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

Hot water heater doesn't work 2 years old


First I would check to be sure your propane tank(s) are not empty and valve is not turned off and that the required gas pressure is being delivered to the unit i.e. pressure line tubing is not kinked or leaking - pressure regulator is operating properly.

Another culprit could be the thermocouple is malfunctioning or is not positioned properly, hence not allowing it to sense the flame.
