Furnace runs but will not ignite
Our furnace started this last night. It will come on and do the blow out thing and then you can hear it click to ignite but it doesn't ignite. After 3 attempts it turns off. Any suggestions?

When it did run, what did the flame sound like? Do you hear the flame attempt to light? If so, its not the sail switch or gas valve or supply.
Mine used to lock out regularly like yours, until I realized when it tried to light or did eventually the flame was noisy, rough & loud. Turned out the fan was blowing the flame off the burner, so I slowly restricted the air intake with tape until it quieted down. Works perfectly now.
