QUESTION:I've scanned several previous messages on this recurrent subject, but
had a few intricate questions not addressed.
Have a 1983 Magic Chef furnace. The pilot light went out during a big
rain storm...no apparent water in the furnace itself, but some nearby.
Anyway, went through lighting procedures and pilot light will not
light. Realize it may be thermocouple and will change that tomorrow.
But questions:
1. Do I simply unscrew the thermocouple to take it off?
2. The pilot has two flames, one directed more toward the burners and
one directed downward toward the thermocouple..is this normal?
3. My thermocouple is fairly loose, and can be moved up and down the
flame. Is there any one spot in the flame that I want it to hit, and
should only the tip hit this flame or should a large swath of flame hit
a large part of the thermocouple?
Okay, those questions will have to do for now. Must get under covers
before hands freeze in unheated house. Seriously, it's about 48
degrees outside, but it would be nice to have this little situation
behind me..any ideas?
ANSWER: The pilot should light regardless of the thermocouple condition.
If bad, it would just keep the pilot from staying on.
Just the tip od the T/C need get hot. The tip is positioned
just outside of the flame core.
Some T/C just pull out of a spring holder, others are screwed in.
Assuming the gas is turned on, see if you can hear any gas
from the pilot burner when the knob is held down. If not,
the pilot burner may be clogged or (unlikely) the gas control
is bad. If you're more daring, unscrew the pilot burner
line at the gas control to see if gas is available at the port.
