You replaced the thermocouple in your furnace but the pilot light still goes out when button is released?

The pilot flame has to encompass the top half inch of the thermocouple. A dirty pilot will sometimes point the flame away and therefore not heat the thermocouple enough to hold. Take a small rubber hose about two feet long and point it at the pilot orface and blow through the hose to remove the ash on the pilot surface Now relight and try it out.

You replaced the thermocouple on your furnace but pilot still goes out when button released?
control valvue ( relay ) internal on Gas control valvue is not switching, replace gas control valvue, By:Joe Draw1.com
What if your gas furnace will not stay on you push the reset button and that works for an hour or so you had a technician tell you that it needed a filter replaced He did that for 89 dollars but still?
This sounds more like a thermouple or dirty pilot light than a filter. If this reset button has a gold color tube leading down to the pilot light this is the thermocouple and you have to push the reset because it is a safety and is keeping the gas valve from opening. If the pilot light is staying lit but the gas valve will not open until you push the reset then the thermocouple is weak and needs to be replaced. Also, filters are $3-$4 apiece. Order a dozen and learn to do this yourself.
New thermocouple pilot still going out why?
Control valves do go bad, but not that often. The tip of the thermocouple is in the flame? Holding the pilot button down long enough for it to heat? Sometimes the first time you light it, it takes a little longer for the thermocouple to work. Good clean connection on the valve end of the thermocouple? That's all I can come up with at the moment.
Need help about force heater why wont the heater stay running when the blue button is reslease after 30 sec?
You might have to try pushing the button for longer, or you might have a bad thermocouple.
Why does your thermocouple keep going out?
If the pilot flame is too high a thermocouples life could be shortened. Check the specs of the unit supplied by the gas valve for the working pilot pressure. Or put the gas valve in pilot and depress the pilot push button. Keep the button down with a small screwdriver, remove the thermocouple from the gas valve and check the millivolts on the thermocouple. Place one lead on the copper tubing and the other lead on the end of the thermocouple, the silver looking part that touches the inside of the gas valve. With the pilot flame on you should read anywhere from 22-29 millivolts. Anything below that is a sign that your thermocouple is failing. It might work for awhile, but it will probably go out in the middle of a long cold winter night. ;)
When a window is maximized the button replaces the Maximize button on the title bar?
Yes, when full screen the full screen button is replaced with a down size button (and vise versa)
What should I do if my heater does not work after power outage?
I'm not sure why your furnace would shut off after a power outage but first check your breaker in the breaker box to make sure it is in the on position. If this is not the problem remove the cover on furnace and look for a red reset button on the pump. Press this button and hold for a second or two and you furnace should restart. If however it shuts down again you have other problems and will need a furnace repairman.
What causes the gas flow to stop when you let off of valve when lighting pilot?
Pilot light is a safety item; to light the pilot, you need to heat up an internal thermocouple; When hot enough, thermocouple will hold open the gas valve on pilot light. If the pilot shuts off when you release the "button", either (1) you did not hold it in long enough & heat up thermocouple sufficiently -OR- (2) the thermocouple has gone bad. Replacements are standardized, easy to find, and well under $10 each, but, sometimes difficult to install.
How do you change a therm-coupler on a water heater with no opening to the polite light area?
I'm guessing there is a cover over the opening with a small window in it to view the pilot light and you push a sparker button to light it? I haven't changed the thermocouple on one of these but have installed several new ones like this. If this is the type you are working on, the cover plate should be held on with a screw on each side. I think the manufacturer intends for you to take the entire burner assembly out and replace it or buy a new heater. The thermocouple can be replaced once you have the burner assembly out. Disconnect the main gas line that goes to the burner and the smaller one for the pilot light and the thermocouple. The assembly comes straight out of the hole with the cover plate. Put a new thermocouple in place and re-install. Another thought, you are sure it is gas and not electric? Just asking.
