Furnace turns on the igniter glows but does not ignite (the gas valve is not turning on) it does this 3 times before turning off the circuit board blinks 1 time.. I replaced the flame sensor and it still does the same thing checked the gas valve and its not getting 24volts to it.. anybody have any ideas??

There are some safety relays in different places on the furnace, look for them and reset them if needed.

How do you reset those safety relays?
