Description
The Lennox 18L07 Blower Relay is an electrical switching component used to control and protect blower motor operation by managing power flow based on current conditions. It is designed with a 1.6–2.5A operating range, a 690V rating, and a single-phase configuration for compatibility with select control circuits. The relay responds to overload or abnormal current conditions by interrupting power to prevent motor stress and support controlled restart behavior. In HVAC systems it is fitted inside air handling control panels to regulate blower motor activation, ensuring coordinated airflow delivery through ducted during system operation.
