Systems and methods of for controlling and appliance are provided. A control system for operating a load of an appliance can be provided. The control system includes a processor and memory device. Memory device is configured to store instructions that when executed by processor cause the processor to perform operations. Operations include determining an operational state of a first load control device, generating a first control signal based on the operational state of the first load control device, determining the operational state of a first load control device enable circuit; generating a second control signal based on the operational state of the first load control device enable circuit; generating a first load control signal based on the first control signal and second control signal; and operating a second load control device based on the first load control signal.
