Abstract: Described herein are systems and methods for modulation based on carbon monoxide sensor data. Specifically, a sensor housing including a sensor may be provided within a heating appliance. The sensor may be configured to measure carbon monoxide levels within the heating appliance. A controller may process the data from the sensor to determine when the carbon monoxide levels rise above a threshold carbon monoxide level. When this condition occurs, the controller adjusts the operation of a component of the heating appliance in an attempt to reduce the carbon monoxide to satisfactory levels. For example, the controller may increase a speed of an inducer or may adjust a gas valve of the heating appliance.

Abstract: Described herein are blower shelf slide rails. The blower shelf slide rails may be universal rails that may be provided within a heating and/or cooling appliance, such as a gas furnace (however, the rails may also be used in other system as well) and are configured to receive a shelf that is used to hold a component of the heating and/or cooling appliance, such as a blower (also referred to as an “inducer,” “inducer fan,” “blower fan,” or the like). The blower shelf slide rails allow for the shelf (and the component held on the shelf) to be easily added to and removed from the heating and/or cooling appliance for maintenance or replacement with another component. The blower shelf slide rails also provide modularity to the heating and/or cooling appliance as they are configured to receive different types of shelves and/or different types of components without any other structural changes to the heating and/or cooling appliance to accommodate the different shelf and/or component.

Abstract: Refrigerant sensor mounting mechanisms are provided herein. The mounting mechanisms allow the refrigerant sensor to be positioned at a bottom portion of a heat exchanger of an air conditioning system such that the refrigerant sensor is proximate to the drain pan of the air conditioning systems. The mounting mechanism may also allow for the refrigerant sensor to be mounted to the top of the drain pan, in some embodiments. By positioning the refrigerant sensor at this location, the refrigerant sensors are more likely to not only detect a refrigerant leak, but also detect the refrigerant leak quickly, as the leaked refrigerant is likely to settle at this location at the bottom of the air conditioning system.
