Heatcraft 71994035 Fan Delay Relay 1/2" Refrigeration Control Component

The Heatcraft 71994035 is a Fan Delay Relay designed for use in commercial refrigeration systems. This relay controls the timing of evaporator fan motor operation, ensuring fans engage and disengage at the correct intervals during defrost cycles to protect system components and improve efficiency.

Key Features:

• OEM Heatcraft replacement fan delay relay
• 1/2" connection size for compatibility with standard refrigeration system configurations
• Controls evaporator fan operation during and after defrost cycles
• Helps prevent warm air circulation immediately following defrost
• Designed as a direct OEM replacement for Heatcraft refrigeration units
• Ensures proper fan sequencing to protect product temperature integrity

The fan delay relay is a critical control component in commercial refrigeration evaporator coil assemblies. By delaying fan motor restart after a defrost cycle, it allows the coil to return to proper operating temperature before resuming airflow — reducing energy waste and preventing warm spots in refrigerated spaces. The Heatcraft 71994035 is the correct OEM part for compatible Heatcraft unit coolers and evaporators.
