This sounds like the thermocouple. I would clean the stub end where the pilot flame hits with steel wool. If this does not cure the problem, you may need to replace it. This item can be found at most hardware stores such as Lowes. Be sure to buy the correct length.

Dust build up inside the pilot light burner assembly. A clean pilot makes noise and has a blue flame when it is burning. A dirty pilot has a quiet and smaller flame with an orange tip.

Bending it will ruin it. You need to find out why the pilot flame is not as strong as it should be.

It is usually caused by bugs or spiders having gotten into the small air mix jet of the pilot assembly and died or built a web or, there is some dirt from the fuel that is partially clogging the fuel tube leading up to the pilot assembly, or plugging the orifice.

Yes this is probably the thermocouple connection.

Just remove the end of the thermocouple from where is goes into the gas valve and leave the end that goes into the flame in place.

Clean the end of the thermocouple connect by scraping off just a little metal from the end just about there the nut tightens the thermocouple into the gas valve. After you have exposed some new metal do the same inside the valve where the thermocouple seats into the gas valve.
Use a small pic or similar item to scrape inside the gas valve to expose some new metal there also.

Now reassemble the thermocouple into the gas valve and see if the heater works.

Here is a link with some more instructions.

SOURCE: PILOT FOR EMPIRE WALL HEATER WONT STAY LIT. I HAVE

are you sure the problem is with the thermocouple? is the pilot sharp and blue? it is unconnon for the magnet in a gas valve to go bad but it does happen. place the thermocouple in the valve and with it in front of you heat it with a match or lighter for 30 sec. now try and light the pilot quickly. if it lights the the problem would be the pilot, if not then the valve. is this a milivolt system or hydrolic t stat.

Hold the pilot button down for a full minute after it lights, then release. If this does not work then the thermocouple is not adjusted where the flame is heating it or you just have a faulty new thermocouple.

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.

I have ventless natural gas heater , u can lit the pilot , but when u let up off the button the pilot goes out . have replaced thermocouple the same problem pilot will not stay lit. have also used air...


When you light the pilot, hold the button in about 1 minute to satisfy the thermocouple. Once the thermocouple is hot and satisfied, turn the gas to "ON". You may have to extend the time a bit, but 1 minute is usually enough.

Best regards, --W/D--

Natural gas hot water heater not stying lit


Probably a bad solenoid in the gas valve. Higher voltage of a new thermocouple keeps it open longer but it still fails over a period of time. Look into a new gas valve for the water heater.

Wont stay lit


there is a thermocouple on this heater just like on a water heater. I have this heater and have to do this periodically. You will have to take a few screws loose but it is an easy repair. There is a tube that delivers the gas to this thermocouple and inside there is an orfice that meters the gas. Take a safety pin and clean out the end and it should stay lit for you

Sounds like the thermocouple is not working or the flame is not hitting the thermocouple. It may take 30 seconds of flame or longer to keep it on. Check for a loose connection at the gas valve.

Either a 30# or 110# tank of propane will work. You might even get by for a short period of time using a gas grill tank, depending upon how cold it is outside.
