You probably need to go through your under storage to get to it as I’m guessing it sits on top of your water heater and likely only has an exhaust port on the outside of your unit.
That’s how our pinnacle is. If you’re looking for the reset switch, it’s on the top and in the middle of the unit and right next to the outside wall.
Nothing easy about working on a furnace. Clearing out the storage area, removing the complete wall. And all those wires. Take pictures of everything. Always good for later.
