This is a safety sensor that will measure the air pressure inside of the combustion chamber. The vacuum pressure switch allows the auger to run as long as there is sufficient negative pressure present.
This switch is specially made for your stove with
just TWO electric connections and only ONE port for easy replacement.
Some generic switches on the market have three electrical connections and two ports to install the wires and hose; a bit confusing - which one will you use?
Here are a few common reasons for missing negative air pressure:
The exhaust fan fails.
A stove door is not entirely closed. (don't forget - check the ash drawer door).
The exhaust pipe or vent is clogged.
The vacuum switch is easy to identify because he is connected to a tube of about 1/4" diameter. The combustion fan creates a negative pressure at the combustion air intake or exhaust fan housing. A diaphragm located inside the vacuum pressure switch closes the normally open switch if the negative pressure is sufficient.
If the negative pressure drops below the designated range, the switch opens and interrupt the power to the control board, to the feed motor and igniter.
It is a good practice to replace the high limit switches as well:

Auger Safety Switch F250
#80390
High Limit switch L170
