Upon inspection, it was determined that the furnace's control board was malfunctioning, causing operational issues. I identified the faulty control board as the root cause and confirmed that the problem was covered under warranty. I proceeded to replace the control board with a new one, ensuring all connections were secure and the system was properly configured. The furnace was tested post-replacement to verify that it was functioning correctly. The parts and labor for this repair are fully covered under the existing warranty.
