I have a high efficiency YORK FURNACE.
MODEL # P2UUDD12N09501C
SERIAL # EBAM075648

I know what the problem is with my furnace. The flame sensor needs to
be cleaned. I have no idea where it is located. My ex moved out
almost a year now and he is the one who cleaned it before. Can you
please send me detailed instructions on where it is located? Right
now we are heated our enclosed family room with a space heater and
the rest of the house is 50 Degrees and lowering. I have 4 children
and 3 pets to keep warm and Michigan weather today is supposed to be
at their lowest degrees for this winter season. PLEASE HELP?

THANK YOU...
Sincerely Tammy
