QUESTION:What's most likely possible problem.....
Furnace Sequencer?
Furnace Thermostat? (Not wall unit - it seems to oprerate OK)
Thermal Sensor feeding data to the Furnace Thermostat?
Dirty Ducts?
Can anyone vector me to an on-line site with an illustrated parts
breakdown?
Can find no trace of the part number on-line. Any suggestions?
ANSWER: 80,000 BTU unit....and if I am reading it right, about 6 years old....no
mention of that model in any of the lit that I have from 98 till now.
Closest unit today is the Diamond 80.
Possible cause: Flame sensor, reversed polarity at unit, bad ground.
Could be..but...not after 30 seconds...normally those will go bad, and stay
bad..as in test open each time...IIRC, there are 3 on that unit....
York does not have such avalible to the general public, and the
contractors information is on CD ROM.
What part number are you looking for? You mean the furnace serial number and
model number?
You will hate this, as most do, but the BEST thing for you to do, is to
FORGET trying to fix this yourself.
IF cleaning the flame sensor does not solve the problem, and the unit does
not have a led that flashing a code at you, telling you what is wrong, you
need to call a tech out, as messing with a gas unit is asking for trouble.
Even if you had a LED flashing out a code, its possible that is only part of
the problem.
Try cleaning the flame sensor, if it has one. It will be a silvery rod by
itself that is in the flame front. IF that does not work, you could have a
bad gas valve, or control, and thats best left to someone that can not only
get the right parts, but install them correctly...not saying you cant.
