Since yesterday Pilot light in furnace was out so i went out bought
thermocouple and replaced it. I wasn't able to light up pilot light
after so many tries I held i down for 15 minutes. Finally it woked and
remains lit. But when I turn on the thermostat(manual) not automatic it
remains on then goes off. Also other thing i noticed it if put the
thermostat to max pilot goes out right away. Could it be Thermostat or
something else? Thanks
