In response to Re: Gas furnace and Pilot light
: I have a gas furnace that the pilot light will not stay lit. In the pilot lighting mode, plenty of gas pressure to the pilot and it stays lit as long as i hold the manual pushbutton down. When I release even after holding for a long time, the pilot goes out.
: I understand that the thermocoupler is supposed to heat up, generate a voltage which then should pull a solenoid to allow gas to continue to flow. Is there a way to measure the voltage produced from the thermocoupler
: to see if it's the coupler itself or the solinoid within the control unit ?
: thanks

in order for the thermocouple to work it must be in the hottest part of the flame. this is the first check, if it is not replace it. it's easy and cheap.
