Abstract: A level sensing device (10) for a drain pan (50) which collects fluid from a source of fluid (40) in an associated HVAC unit (39). The drain pan (50) has at least one side wall (55). The device (50) has a bracket (12) having agenerally U-shaped portion with first and second legs (16, 18). The generally U-shaped portion serves to mount the device (10) to the at least one side wall (55) of the drain pan (50). A shelf (20) extends from the second leg (16) of the bracket (12). A switch (24) is secured to the bracket (12). The switch (24) is triggered when the fluid level (65) rises above a predetermined level causing electrical power to the associated HVAC unit (39) to be shut off. An HVAC unit (39) employing this device is also disclosed.
