Furnace won't start reason #5 resolved
The gas was turned off so someone could work on the line or other reasons. Now the gas is on, but the furnace won't light. The system went into lockout. It will try to light 3 times then locks out. To reset it turn thermostat off. Turn the breaker to furnace off. It is in the gray panel box where the power is. Turn it all back on. If the furnace doesn't start in 5 minutes, do it again.
