Whitfield Advantage/Quest Pressure Switch Kit

The Pellet Stove Pressure Switch Kit, by Lennox # 12145903.

The stove vacuum switch indicates to the stove that it has an airflow through the venting in the proper direction. If the vacuum switch doesn't register a pressure difference, it will not remain closed. When it opens the auger is stopped, depriving the stove of fuel and leading to shutdown

  • I have a Whitfield Advantage II-TC. The manual which I downloaded here shows the POSITIVE PRESSURE SWITCH pn# 12125903 and that coincides with the switch on the stove. This part number is 12145903 (4 instead of 2). Everything looks correct and I am sure this is the right part, but your thoughts?

    According to the manual this is the correct replacement part for that pellet stove.

  • Does it come with the hose?

    The switch does not come with a hose however the SRV7000-0450 hose fits it well and can be used.

  • I have a Whitfield profile 30-2 pellet stove. I need a pressure switch. Part no. Installed is 16020016. Is 12145903 the replacement? It looks identical. Other manuals I’ve looked up say part number 16050001 is the replacement, but it doesn’t look the same as the original .Thanks for any input

    Whitfield has changed the design of the vacuum switch they originally used at the beginning of manufacturing this pellet stove. Since then they have started installing the vacuum switch seen here: 16050001
