Lennox G61MPV-60C-090 Air Pressure Switch
The actual job of this type of switch is to sense if the main blower is running properly. This switch is just one of the many indispensable devices designed to keep everyone in the house safe. Most air pressure switches are designed with a reset that is manual instead of automatic, which, of course, means that it would have to be reset by hand or the entire system will not run.
Common Symptoms of a Bad Pressure Switch
- The correct indoor temperature is almost never attained.
- Incorrect volt range being read.
- The furnace or AC will not run correctly.
