The Lennox 104772-01 Delay Relay is a high-performance electrical component designed to optimize the operation of HVAC systems, including residential air handlers and furnaces. This time delay relay is engineered to manage the timing of the blower motor, ensuring that the fan continues to circulate air for a set period after the heating or cooling cycle ends. By clearing the ducts of remaining conditioned air, this part significantly improves energy efficiency and indoor comfort levels. If your HVAC system is experiencing issues with fan sequencing or the blower is cutting off prematurely, this relay is a vital replacement part to restore proper system logic. Built with durable materials for long-term reliability, it ensures precise electrical switching and helps protect other sensitive system components from unnecessary wear and tear.
Type: Time Delay Relay
Size: Small
Application: Used in HVAC air handlers and furnaces to regulate blower fan timing and improve heat exchange efficiency.
Specifications: Standard low-voltage control circuit compatibility; features precise time-delay sequencing for fan-off cycles.
