Aprilaire 4739 Female Disconnect Assembly
The Aprilaire 4739 Female Disconnect Assembly is an essential OEM replacement component designed specifically for modern Aprilaire 700 series humidifiers. This relay wiring harness facilitates a secure electrical connection between the motor board and the internal components of models such as the Aprilaire 700A and Aprilaire 700M. Engineered for HVAC system maintenance, the assembly features 10-inch brown and yellow wires equipped with 3/16-inch spade connectors for a precise fit. It is designed to snap directly into the motor board orifice plate, ensuring a stable interface with the 4240 male wiring harness. This humidifier repair part is specifically compatible with newer power humidifiers featuring the blue or gray housing. By replacing a worn Aprilaire 4739 assembly, technicians can restore proper fan operation and electrical signal integrity, maintaining the peak efficiency of the whole-home humidification system through durable, high-quality HVAC connectors.
Key Benefits:
- OEM Compatibility: Precision-engineered for perfect integration with Aprilaire Model 700, 700A, and 700M units.
- Secure Electrical Interface: Features 3/16-inch spade connectors to ensure a reliable connection that prevents accidental disconnects during operation.
- Easy Installation: Designed as a snap-in component for the motor board orifice plate, reducing labor time during repairs.
- Durable Construction: Built with high-grade wiring and heat-resistant connectors to withstand the internal environment of a powered humidifier.
Common Questions:
Will this part fit my older almond-colored Aprilaire 700?
No, the Aprilaire 4739 is designed specifically for newer models with blue or gray cases. Older almond-colored units typically require the 4239 assembly.
Does this assembly include the male wiring harness?
This is the female disconnect assembly only. It is designed to mate with the Aprilaire 4240 (RP-4740) male wiring harness, which may need to be purchased separately if also damaged.
What is the length of the lead wires?
The assembly includes two color-coded wires (brown and yellow) that are 10 inches in length, providing ample reach for standard motor board configurations.
