Join us on an insightful journey through HVAC troubleshooting as we uncover the mystery behind a burnt contactor that halted a condenser fan motor operation. Witness the stepbystep process of diagnosing and resolving this issue, revealing the underlying culprit causing the malfunction.

Upon getting the condenser fan motor back in action, our diagnostic exploration led us to discover intermittent cycling in the pressure switches. This rapid cycling likely contributed to the demise of the contactor. To combat this issue and ensure optimal functionality in low ambient conditions, we opted for a simple yet effective solution the installation of a new ICM 334 universal head pressure control system.

In this video, we showcase the entire process of replacing the conventional setup with the ICM 334, highlighting its features, functionality, and how it tackles the challenges posed by fluctuating ambient conditions. Witness firsthand how this upgrade provides stability and efficiency, preventing future contactor burnouts and optimizing the performance of the cooling system.

Whether you're an HVAC professional seeking practical solutions or an enthusiast eager to learn about troubleshooting and innovative solutions for low ambient issues, this video offers insights and a detailed guide to implementing the ICM 334 control for enhanced system reliability.
