Door switches are safety interlock components that interrupt unit operation when an access panel or combustion air door is opened during service or maintenance. This prevents the unit from firing or running while a technician has the enclosure open, protecting against accidental ignition and uncontrolled airflow. The rz116023 is an OEM-style replacement part intended for installation by qualified HVAC technicians familiar with commercial and industrial gas-fired heating equipment.\u003c\/p\u003e\u003cp\u003eThis door switch is used in REZNOR UDAS series gas-fired unit heaters, which are common in commercial and industrial applications such as warehouses, manufacturing facilities, and garages. The switch is typically mounted at an access door or panel on the heater cabinet. When the panel is closed, the switch completes the control circuit and allows normal operation. When the panel is opened, the circuit is interrupted, shutting down the burner and blower as a safety measure. It is a direct replacement for units requiring this interlock function.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM-style door interlock switch for REZNOR UDAS series unit heaters\u003c\/li\u003e\n\u003cli\u003eInterrupts control circuit when access panel is opened for safe servicing\u003c\/li\u003e\n\u003cli\u003eDirect replacement fit for applicable UDAS heater models\u003c\/li\u003e\n\u003cli\u003eSupports proper safety interlock operation required by heating equipment standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement door switch for REZNOR UDAS series unit heaters requiring this safety interlock component.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician.
