Repeated tripping of the 626465R is typically symptomatic of underlying system issues such as a dirty air filter

a trip is a diagnostic indicator that airflow or combustion gas removal is compromised

these components integrate directly into the actuator housing

How do I verify if the 4520-0015-000 is failing

MARS 33242 Relay Repeated tripping of the 626465RThe MARS 33242 Relay is a specialized 24V SPST NO time delay relay engineered for precise control in HVACR systems. As a veteran grade HVAC compressor time delay solution, this component utilizes a solid state PTC (Positive Temperature Coefficient) device. When current flows through the control circuit, the PTC element heats an internal snap acting disc, facilitating a reliable make or break contact transition. This thermal time delay relay is
