Hi,
It could be about three things...

The new thermocouple is bad

The gas valve was bad to start with and the problem was not the thermocouple

Or you didn't get he new thermocouple started into the gas valve right. It is easy to get it cross threaded.
Take the thermocouple back out of the gas valve and try to make sure you get it threaded in straight. and thighten firmly.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

How do u light for hot water? 1992 bounder


Depends on the gas valve on the heater. Early models you have to use a match near the pilot light while holding the red button down. Continue to hold the red button down for 30 seconds or more. Slowly release the red button . If the pilot light goes out then replace the thermocouple. That looks like a small diameter copper tube that goes from the gas valve into the burner to make contact with the flame. If your heater has a piezo spark unit on it. you go thru the same as above but without the need for a match

Why does the flame shut off before a hot to warm temperature can be achieved


I would question the Thermo couple. It pretty much runs the whole show. Inexpensive quick fix. It's the small tubing that is connected to the gas valve. The other end is a bulb that sits over the pilot flame.. Remove the old and match it up at the hardware store. Install new coupler ensuring bulb is directly over the pilot flame Common iten. The thermocoupler alks to the gas valve. If the pilot flame extinguishes (goes out) the bulb cools and shuts down the gas valve so the pilot gas feed doesn't permit raw gas to accumulate, avoiding the need emergency Services. . You will not get the heater to fire until the bulb is good and hot. The red push button ,when depressed will allow the pilot flame to be lit. Hold it down until the heater fires, indicating the T-coupler has reached its operating temp.Good Luck-Ned

you need a new thermocouple. u can either get one from a plumbing store but the can be a bit fiddley to fit or u can get the proper Brivis one it just pulls out and u put the new one in. then u have to re light the pilot light. make sure u hold it down for at least 45 sec to make sure that it is getting hot enough when u release it it will stay alight then turn gas valve to the on position

We dont think our cylinder is on we have just moved in and have no hot water


The question is? I'll assume you cylinder is the water heater, right?
On the heater (water) you will find or see the red controls and a sheet metal cover over a hole. Remove the cover and this is where you light the pilot light. Press down on the red dial and turn it to pilot. In that position you will be able to press the red button . Geyt a long match or bbq lighter, then, holding down the red button dow for a minute or so and place a match or lighter into yhe area where the lines go The flame will catch the gas and lite the pilot if yo simply move your glame around. When the flame catch on the pilot, continue holding the button down for sveral minutes until the buld the flame isheating gets hot. Then release the buton and turn the main dial to on. The main burner should fire up. If not, and the pilot goes out, repeat the process. The bulb in the pilot flame is a thermocoupler that shuts all gas off if it doesn't detect a pilot flame, so hold the button down longer. If the pilot goes out when you release the button, The thermocoupler is no good and needs replacing. Good Luck_Ned_

Water heater will not stay lit even after replacing thermal coupl


The pilot must encompass the thermocouple "bulb" in order for the thermocouple to generate enough current to keep the pilot valve on. You must also hold the red button down for a long enough period to get the thermocouple hot. If the pilot is not large enough, it could be due to a clog in the pilot orifice at the pilot itself. Sometimes a couple of passes over the end of it with fine steel wool is all it takes to clear it.

Hope this helps. Feel free to share what you found. Thanks.

are you holding button down long enough for thermal coupler to warm up? after pilot lights up, don't immediately let go of button for about 15 to 20 seconds then let go and pilot should stay on. If not, you may need a new thermal coupler for that water heater

Thermo coupler on all the time, push in button, shuts off gas


Bad Safety valve. (valve w/red button). Thermocouple keeps the magnet open to keep pilot and so gas can flow to burner. Make sure pilot is clean and strong and hitting thermocouple. If it doesnt stay lit replace Safety Valve.
