Pilot light on heater

We have had the heater for three years and this is first problem. Before, the pilot lit on first click and never went out. Now, it takes several clicks (sometimes I even manually light it). Then when the heat comes on and cycles off, the pilot light will remain on for a while then just go off. How can I keep the pilot light lit (and a bonus would be to make it easier to light)?

Thanks,
Tom Thornell

Check the millivolt generator is working. this is the copper colored tube in the flame path. for spark perhaps the gap is too wide. the flame sensor electrically keeps the pilot valve open.

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.

The pilot light will not stay lit. A new


Try cleaning the orfice for the pilot light. You will have to dis-assemble the fuel lines from the thermostat to the burner to get at it. The orfice has an extremly small hole in it, do not make it any larger, just clean it out.

You should the value there should be a pilot ajustment screw
some times it is hidden under another screw but should be close to where the pilot light line hooks to the gas value

My 1.5 yr old gas water heater has a pilot light problem


YOUR WATER HEATER HAS WHAT IS CALLED A STANDING PILOT-STAYS LIT ALWAYS WHEN THE PILOT GOES OUT YOU LOOSE EVERYTHING. YOU HAVE TO REPLACE THE THERMOCOUPLE WHICH KEEP THE PILOT LIT. ONCE THE PILOT IS LIT THE THERMOCOUPLE SENDS IN MILLIVOLTS TO THE BURNER TO SAY ITS READY FOR BURNING
IF YOU ARE NOT FAMILURE WITH THIS REPLACEMENT PLEASE FIND SOME ONE WHO CAN. IT IS NOT HARD TO DO ASK A NABOR OR FRIENDS SOME HAS TO KNOW HOW. SERVICE COMPANYS ARE OUT FOR THE MONEY FOR A 10 MINUTE JOB

GWN10T pilot blows itself out


You must clean the pilot regularly to ensure it burns properly. Use a small can of air for cleaning computers and blow air through the pilot to remove dust and small particles that accumulate in the pilot barrel. Use several burst being that it is 2 years old and has not been blown out. THe manual references cleaning the pilot in the maintenance section.
