Trane Furnace's red light flashing 3 times tells you either there is an issue with your furnace pressure switch or a fault with the ventilation. Plus, clogged inducer fans, blocked condensate drain and pumping lines are also responsible for the red light blinking 3 times. To fix your furnace's 3 blinking instantly, check and validate. I was hoping someone could help me. I have a 6 year old Trane XR90 Furnace that blinks 3 red lights when it calls for heat, then it shuts down. 3 Red Lights means "Pressure Switch Error". This is what I have tried to fix this. · I have unhooked the hose that runs from the switch to the gas valve and to the burner box and cleaned the hose.
