 |  "Blower doesnt start"
, posted Fri 24 Oct 18:24:  
I have lennox ugf90. it's about 4 years old. Air filter is new.
The problem that i have is it doesnt blow hot air.
Thermostat initiates the heating sequence, the combustion air inducer does start and spins for a couple of minutes and then shuts off, without blower ever turning on. I get LED1=off LED2=slow flash
which means Blocked inlet/outlet exhaust or condense line blocked or pressure switch closed (according to manual). Can somebody tell me how to check the blockages and the pressure switch?
Also, i dont see any flame inside burner box when the combustion air inducer runs. I tried shutting off gas and turning it back on (like it says in the manual) but i still see no flame.
I tried setting thermostat to cool and the blower motor does come on and blow cool air out of the vents. So perhaps no pipes are blocked, its just the ignition thing that doesnt work? Any other ways to ignite the flame?
