Upon arrival, I diagnosed an issue where the heating system was signaling for heat but was not providing power to the heat strips. After a thorough inspection, it was determined that the sequencer was faulty. I ordered a replacement sequencer and installed it, ensuring all connections were secure and the system was properly calibrated. Post-installation, I tested the system to confirm that the heat strips were receiving power and operating correctly. The client was pleased with the resolution and the restored functionality of their heating system.
