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.

You might have to try pushing the button for longer, or you might have a bad thermocouple.


Where is the reset button for Trane XL90?

The reset button for the Trane XL90 furnace is typically located on the control board inside the blower compartment. To access it, you'll need to remove the front panel of the furnace. Once you've located the red reset button, you can press it to reset the system after addressing any issues. Always ensure the furnace is turned off before performing any maintenance.

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. ;)


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.


What if my Laars 2 heater pilot wont stay lit when the button is released?

If your Laars 2 heater pilot won't stay lit after releasing the button, it may indicate a faulty thermocouple or a problem with the gas supply. The thermocouple is responsible for sensing the pilot flame and keeping the gas valve open; if it's defective, it won't allow the pilot to stay lit. Additionally, check for any blockages in the gas line or ensure that the gas is turned on. If troubleshooting doesn't resolve the issue, consider contacting a professional technician for further assistance.
