Welcome to the forums.

Do you have any power to your furnace/air handler ?
Did the power/service switch get turned off ?

Does the furnace part (if it has one) work.
Does the inside blower work if you put the thermostat in FAN ON mode ?

As PJ has already posted start with the light switch by the furnace.
If that switch was already on and the indoor fan does not work as well as the outdoor unit, check the low voltage wires outside by the unit for damage.

Many Lennox furnaces have a low voltage circuit breaker instead of a low voltage fuse. Usually pops up when tripped. I wish every brand used them.
