Most likely it's time to replace the thermocouple, the safety device that makes sure the pilot is lit. New thermocouples are cheap and you can find them at most hardware stores and the big-box places (Home Depot, etc.)

Here is a site with basic information to get you going.

SOURCE: Rheem 40 gallon gas hot water heater, pilot light

To make a short story long (I need to include all details, sry)…

I got up one morning and realized that we did not have hot water. I re-lit the pilot light and as soon as the burner went out from heating the water up, the pilot light would go out. After reading several posts regarding this issue, it seemed apparent that the thermo-coupler was the problem. Since I am a little bit handy around the house and very tight when it comes to opening my wallet, I bought the device from Lowe’s ($8.98) that was recommended by my online advisors and after a few googles, figured out how to change it. No help. The pilot light still goes out.

I gave up and went to Home Depot to purchase and schedule the installation of a new hot water heater.

STICKER SHOCK

A new Direct Vent type water heater costs around $800 with an additional $450 for “special” installation. Add a few fees to that and the grand total came to about $1450.

I felt like I had no choice since my wife and 2 daughters refused to live their life without hot water and I had no clue about how to fix the dam thing.

The plumber assigned to the installation stopped by to evaluate the site conditions and quickly noted to me that the 8 year old water heater tank was in good condition and that the gas controller was probably faulty, which could be purchased online from the manufacturer. I quickly cancelled the Home Depot order and purchased the controller for about $120 after shipping and tax. Immediately after the installation it seemed that the problem had been solved. A few days later the pilot light went out.

I called the plumber and explained the situation and he recommended that I purchase another controller because the one that was shipped to me was probably bad. I searched around town and found a plumbing supply company that had the correct model in stock. Two days later the pilot light was out. I cleaned up the controller and returned it to the store and asked the plumber to please schedule a visit to repair this dam thing.

When the plumber arrived, he hooked up a gauge in several locations and confirmed that the correct amount of gas (cfm) was being delivered to the controller, pilot light and burner. He then proceeded to remove the fire box to make sure that the igniter, thermo-coupler and pilot tip were set properly. He inspected the pilot light tip and said that he found the problem. Using about a 1/64” tip drill (can be purchased at a welding supply store), he cleaned the tiny hole that releases gas to the pilot light. I felt a sigh of relief because I was certain that the problem had been solved. $65 dollars (plumber’s fee for an hour of work) and 4 days later the pilot light went out.

I called the plumber and he said that the controller that I purchased online must be bad. Too embarrassed to return to the first plumbing supply store, I found another one in a different town that had the correct model in stock. Three days after changing the controller the pilot light went out. I returned the controller and a six pack later I decided to do some extensive googling.

The key term here is “DIRECT VENT”. This seems to be a very common problem with direct vent water heaters and I was about to find out the reason for this phenomenon. I read a post by an individual who wrote that if the vent becomes detached that the inflow of air can become contaminated and extinguish the pilot light. I decided that before I spent any more money on a plumber that I was going to take the vent apart and find out what makes it tick.

My direct vent system has 2 parts to the venting, an inner pipe (3” nominal diameter) that serves as the exhaust and the outer pipe (5” nominal diameter) that serves as the internal flow of air which supplies the pilot light and burner with oxygen. On the outside of the house a vent hood helps to segregate the two by extending the exhaust about 3” beyond the intake. I looked into the hood at the end of the pipes and discovered that the internal pipe which consisted of a 2 piece slip joint had come loose from the elbow that sets on top of the water heater. This slip joint pipe was not attached at any point with screws or clamps and was loosely setting over the elbow on one end and into the hood on the other end, allowing it to detach. Apparently, when atmospheric conditions were right, the burner idled down from heating up the water and extinguished the pilot light because the intake was saturated with CO2 from the connection failure.

I purchased a section of 3” pipe that was long enough to be installed in one piece. I connected it to the elbow using a stainless steel hose clamp. I had to disassemble the pipe 3 times to make adjustments to the length and position before I got it right, but I should not have any more problems with the pilot light.

The problem here is time. It takes a lot of time to get this right. When the plumbing contractors installed this unit during the construction of the house, there was no one around to make sure that they got it right. It is probably common to use a 2 piece slip joint type connection, but I feel like it should be attached with screws or clamps. In my opinion it is not rigid enough and can detach easily, especially if it is not installed properly. A one piece connection that is attached at one end with a hose clamp and then held in place at the other end by the hood is fool proof.

SOURCE: 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.

SOURCE: pilot light on water heater wont stay lit

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

Sw6p suburban won't stay lit. My 6 gallon hot water heat on my 2007 camper won't stay lit, I go and light the pilot light and it lights but I turn the gas up and it blows out please help


the thermal couple is likely bad .
when you release does pilot stay lit or only as long as you hold the button .

if it stays lit then the thermal couple is good
if it only blows out as you turn on the heat then its draft issue.

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.

Lowe's hot water heater pilot light will not stay


Hi,

If it is one of the new ones with the fancy gas control and the blinking light... does the light blink?? or not??
If it is blinking then the pilot should stay lit...
If it will not blink then the sensor is bad or not in the right place...

Or... the gas control is bad... this is happening alot...

If it is brand new... take it back...

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.
