As Steve reminds you, there are many reasons why a furnace would fail
to fire. If you just go replacing parts, it could easily cost more
than having the repair guy out.

You tried thermostat, and that didn't help. The next part(s) you
replace may be both expensive and unnecessary. At this point in time,
best to call the repairman. Before the weather gets colder, and the
rate schedule goes from "fall" to "winter".

It could also be one of the many safeties that is keeping the furnace
from
firing.
Sure you don't want to call a tech and get it properly checked and
serviced??
