Whirlpool ATR1252CPP0 Air Pressure Switch
The reason for the existence of the pressure switch is to figure out if the blower fan is actually running. A lot of switches are constructed with a manual reset, which means it would need to be reset before the system will continue its normal operation. This switch is a very critical piece of the collection of safety devices in place to keep you safe from harm.
How do you Know when the Switch is Going Bad
- The furnace refuses operate at all.
- Wrong voltage running through the pressure switch.
- The right temp is never fully achieved.
