SOURCE: Pilot Light problem

By controler I am guessing you mean gas valve? The next step, and I am not sure the water heater age rates this ,is to replace the gas valve.

The pilot assembly should look similar to the pic above. Depending on where you live, you may be required to hire a certified plumber to replace the parts. If not you can do it your self. Keep in mind if it's not staying lit you also need to check the thermostat and the thermocoupler before replacing the pilot assembly. There is a good chance it is just the thermocoupler going out. It is one of the first things to check when troubleshooting a pilot light problem with a gas water heater. A thermocouple determines if the pilot light is lit. If it's not lit, the gas valve fails. If that's the problem, replace the thermocouple.


  1. Shut off the gas valve on the water heater and the gas valve on the line near the heater. Remove outer and inner doors, and loosen the pilot and supply tubes and the thermocouple connections to remove the burner assembly.
  2. Step 2 Loosen the screw holding the thermocouple to the bracket. Remove old thermocouple. Bring it with you to the store to ensure you are buying the proper replacement.
  3. Step 3 Install the new thermocouple. Position the thermocouple so that the pilot flame heats 1/2 inch of the tip.
  4. Step 4 Reinstall burner assembly in the water heater. Tighten burner supply tube, pilot tube and thermocouple connections. Tighten thermocouple no more than a quarter turn more than hand-tight.
  5. Step 5 Turn on both gas valves. Check supply tube and pilot tube for leaks with soapy water. If soap bubbles, tighten connections to fix leak. Ignite the pilot light, and make sure the thermocouple tip is heating up. Replace inner and outer doors.

SOURCE: pilot stays lite but the burner wont ignite propane unit

the gas is not coming out of the burner, probably due to rust clogging the holes.

SOURCE: pilot light on water heater goes out frequently

Check the following:

See if your heater has a pilot gas adjustment valve. It should be on the gas control valve somewhere. Not all heaters have these. It will be a screw on the valve that can be turned.

Make sure the thermocouple sensing bulb is squarely in the pilot flame and also check that the fitting where the other end of the thermocouple connects to the main gas valve is tight.

Check the pilot gas orifice (where the pilot gas comes out) for carbon build up - you may need to remove the pilot gas line and thermocouple assembly to get to this. This problem is pretty common.

Check the gas pressure to the heater. Run the hot water in the dwelling until the hot water heater starts. Check the flame on the main burner and see what color it is - it should be blue with possibly some yellow-tipped flames. If not, there could be a problem with the gas pressure at the heater or venting. If the heater has a gas pressure regulator, it may be out of adjustment or defective.

Finally, and this isn't very common, the pilot light can be extinguished if there is a draft problem, usually associated with an issue with the flue pipe venting system for the heater or another nearby gas consuming appliance.

SOURCE: water heater pilot

This is more than likely the thermocoupler. The thermo Coupler is a solid cylinder shape with a point on one end and a thick aluminum wire on the other the tip is situated so that it is in the pilot flame. When it reaches a certain temperature from the pilot it sends a signal for the gas valve to stay open and keep the pilot light. If it does not send the signal the valve closes and shuts the gas off for safety. Solution first make sure you hold button long enough to heat Thermocoupler (about 30 sec) if pilot still goes out then replace Thermocoupler. Can purchase at most hardware stores and all plumbing shops.

When I try to light the pilot, the flame light at the small hole on the outside on the pilot burner


You have a plugged pilot orifice. That small hole is basically an air intake for pilot when working properly, and when it gets a spider web or something in it, the pilot flame will burn rich (orange/yellow). When pilot orifice is plugged, that"s the next closest place for propane to escape, thus, flame . You need to either blow compressed air in to pilot tube end where flame is normally at, and hope it cleans debris out, or use a 3/8 and 5/16 wrench and disconnect pilot tube from end and remove orifice in pilot assy, and make sure small pinhole is cleared in center of orifice. Be careful when removing tube, as it is aluminum and can crack very easily, especially if older. The best thing to do would be to stop at RV store and get a new pilot tube and thermocouple assy, and install new. Not very expensive, and troubles should be over for years to come with regular servicing. New assy, comes with new orifice etc.

My 606 reliance gas water heater run for 5min and pilot goes out


If the pilot will light and stay lit, then ECO is not tripped, and thermocouple is probably good.
If ECO is tripped, then pilot will have no gas.
Usually if thermocouple is bad or installed incorrectly, the pilot goes out immediately after releasing the pilot knob during lighting.
http://waterheatertimer.org/How-to-test-water-heater-thermocouple.html

First thing is to clean water heater air intake and get more fresh air to the water heater and see if that solves problem. Combustion of hydrocarbon requires oxygen that must be pulled into the water heater from surrounding rooms. If water heater is closed off, or located in hot attic that is not correctly vented, or house is tightly sealed, or air intake is clogged, then there is not enough oxygen to support combustion.

Next thing to check is color and size of pilot flame.
If color of flame is NOT clear blue, or if flame is weak, then that says the pilot orifice and burner tubes and burner should be removed and cleaned, along with cleaning combustion chamber.

Additional suspects include combination of things, including: , bad gas control valve, low gas pressure, air in gas line, water dripping down vent and putting out pilot, reverse air flow or backdraft down the vent that blows out pilot, damaged burner parts because of exposure to trace chemicals such as bleach and wax.

Open a nearby window to let in plenty of air and see if problem continues.
Problem might be something simple like vent backflow blowing out pilot, or more complicated like bad gas control, or combination of problems listed below.
Suspects include:
Faulty gas control thermostat.
Air in gas line.
Low gas pressure.
Hot attic air.
Insufficient air, or dirty air intake.
Dirty combustion parts, and tubes.
Thermocouple not sitting in flame.
Thermocouple tightened too much. Finger tight + 1/4 turn. No joint compound or teflon tape.
Bad venting.
Backflow of air down vent pipe caused by tight house and/or other vent fans in house.

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean
Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.

Since pilot light goes out and can be re-lit, problem is probably not thermocouple, gas control valve, or air in gas line. But these things can factor in as contributing factors.
Problem is likely one of following or combination of following including dirty burner parts, tight house, incorrect vent lengths, negative pressure caused by other venting appliances, condensation dripping down into combustion area, and inadequate oxygen supply due to hot or closed-off room or attic location.

Gas water heaters draw air from surrounding area. If water heater is located inside house, then air has to enter home through cracks and when doors and windows are opened. Other gas appliances and vent fans also draw air from same indoor area. When other vent fans turn on, air can be drawn down the water heater vent and blow out pilot light.
Inspect combustion chamber to make sure there is no condensate water dripping down from incorrect vent that is putting out flame. If combustion chamber is dry, then close doors and windows. Turn on all vent fans and gas appliances that vent outdoors, and see if water heater pilot goes out.
Consult with plumber or product manual about proper horizontal and vertical lengths of vent pipe for your model. Have plumber clean combustion parts and inspect vent termination and check gas pressure and bleed gas line.
Add louver opening to outdoors so air can enter room where water heater is located.

Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

Model: 21v30-7p, pilot wont stay lit


You need a new thermocouple - or maybe the Pilot flame is not lined up properly to the thermocouple? The thermocouple is a "sensor" that is heated by the flame - which in turn keeps the gas supply to the pilot light on. It the pilot light goes out, then the thermocouple no longer "senses" the heat of the flame, so it turns the gas supply off to the pilot to prevent buildup and explosion.

I can not get the unit to light.


Make sure the window is big enough. Ok, not funny. Turn the gas on and leave set for 24 hours Light the pilot light and make sure the thermocoupler is at the tip of the flame. hold pilot until the coupler bulb is nice and hot , release the pilot button nice and slow. If the pilot goes out, The thermocoupler is defective. If this sneaking up on it works, then fire up the main burner. Letting the unit sit under the gas pressure for24allows a thorough purging of the main valve. and saturation of any air pockets. Lighting one in cool temperatures is somtimes difficult becase the gas is heavier or more dense than under warm conditions. Sounds dumb, I know. But give it a try and let me know how it goes.Good Luck, Ned
