There is problem with the unit. the 2 flash codes indicates a problem.

i am just not sure what it is.

it could be a low voltage alarm,
a high voltage alarm
freezing evaporator alarm.
not cooling alarm.

reset it by un pluging the unit for 1 minute then plug it back and run it. observe if the compressor would start.
if it start, check if it is cooling,

if it starts to cool, check the coil of the evaporator if it is freezing..

you could trace from there what is wrong with the unit.

pls keep me posted..

kindly use the ask me button,

tnx 4 using fixya,

Furnace blows cold air, ignitor won't glow.


ok this is going to sound funny but it seems as though the polarity is reversed going into your furnance. to correct this proiblem you first need to unplug the unit and where the cord goes into the furnance at that connection disconnect the two wires. Once theses are disconnected switch the wires .All you are doing is reversing the way the electricity flows into the circut board. I would wager that is the problem
