What other problem besides the thermocouple would cause a heater not to stay lite?

The thermocouple only keeps the pilot light. Temp sensor,gas valve, high limit switch,
safety switch,thermostat, would cause burner not to stay lite. Better to post MFG,model, problem.

Why would it mess up the water heater by running it out of propane the propane ran out and now it will not stay lit the replaced the thermocouple and it didn't fix it?
Did you purge the air out of the gas line? This could cause the problem by air being introduced into the line.
Thermal manifold temperature instability ?
Cause: Poor thermocouple contactSolution: Check the thermocouple
1998 Jeep Grand Cherokee limited 5.9 heater problem?
There are several things that can cause heater problems in your 1998 Jeep Grain Cherokee. The most common cause of heater problems is low fluid in your cooling system.
When you lite your pilot light for your water heater then try and turn the temperature uo the burner stays on for a secnd then goes out along witht he pilot light what is causing this?
The thermocouple has to be maintained hot enough by the pilot flame or it will cause the gas valve to shut down all of the flow of gas. The pilot flame is probably set too low (easily adjusted with a screw driver) to satisfy the thermocouple. If not the thermocouple or the gas valve may be bad. I like to keep the flame just high enough and aimed to satisfy the thermocouple and not make it red hot
How do you jumper a thermocouple?
You don't ! It's unsafe and stupid, you could cause serious damage.
Where is the Heater Unit located in a 1995 Ford Fairmont - and what could possiby cause the heater to only blow cold air?
hi, did you faind an answer, i'm having the same problem, Cheers
What could cause heater not to work in a 98 bravada?
If the problem is that the air never gets warm, it's most likely a stuck-open thermostat. If not that, heater core may be plugged.
Your 2000 blazer started blowing out air that was not warm when the heater was on. It started working after about 15 minutes.?
I am having the same problem.. I have already had to replace the intake manifold gasket cause it was leaking, still no heat. We will be flushing out the heater core to see if that's the problem. I may have to replace the heater core, we will see.
What can cause heat to not work in my es350 Lexus?
While there are a variety of reasons your Lexus ES350 heater is not working, the most common 3 are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.
Why does your gas hot water heater pilot keep going out美國瓦斯熱水器母火會熄滅?
This is usually caused by a bad thermocouple. The thermocouple looks like a thick, solid copper wire screwed into the gas valve on the water heater. The pilot flame heats the tip of the thermocouple, causing it to generate a minute electrical current at low voltage, which provides power to an electric valve that controls the flow of gas to the main burner. If you attempt to relight the pilot burner and it refuses to stay lit when you release the button on the gas valve a minute, or so, after the flame has been lit, the thermocouple is the most likely cause. Replacement thermocouples are readily available from most hardware stores and can be replaced by the homeowner, using simple tools, by following the instructions on the package.Another cause of the problem could be a lack of air to the combustion chamber. Newer water heaters require more volume of air due to the addition of a heat sensitive diode to the thermocouple. Not enough air flowing through the combustion chamber to carry the heat up through the flue causes heat build up, which kills the thermocouple. On my water heater, I could light the pilot and the water heater would burn for 20 minutes or so and shut off. The fix included routing the flue straight through the roof and opening floor to allow more air into the water heater compartment.Another possible culprit may be water-heater vent height above the roof. In some situations this may periodically result in a downdraft that could cause the pilot light to go out. If this is the case adding to the vent height may help. Note: building code states that the B vent required height is based on the roof pitch but it must be 2 feet higher than any portion of the building within 8 feet of the vent.Make sure the vent cap isn't missing or rusted through on the roof, it will cause drafts and wind to blow out the pilot.
How does a thermocouple work in a water heater?
A thermocouple is a safety device that when heated by the pilot light produces a small electoral current that holds the gas valve (to the pilot) open. Should for any reason the pilot light go out, gust of wind, service interruption , water splash....whatever. The thermocouple will cool off, stop producing current and the gas valve will close. For example, your water heater is in your basement. A strong wind blows down the stairs and blows out the pilot. Or a few inch's of water flood you basement over topping the pilot. With nothing to stop the flow of gas to the pilot light pan, gas would continue to flow unburned in to the room. Then any ignition source could cause a catastrophic explosion.
How do you know if the heater core is broken on a 92 cavalier?
you can tell if your heater cooling system/core is broke as the car will not produce heat when you turn on the heat inside the car. if it is not blowing heat there could there is a problem. the heater core itself should look like a small radiater, if that is clogged it could cause a problem. can also possibly fix this by doing a cooling system flush this will clear any blockages or expose the problem. if flush works, consider the thermostat. that also will cause no heat on inside.
