    • A tripped reset button is just one possibility. Other potential causes for a non-functioning pilot light include low gas pressure, clogged burner ports, or a faulty ignition system. If you’re not comfortable troubleshooting further, it’s best to call a professional to diagnose and fix the issue safely.

  1. My Rheem AC requires an occasional red button reset to function, typically after periods of inactivity. The unit appears clean, and restarts remain reliable on the same day, but the frequency varies from weekly to months apart. Where should I look for potential issues, considering there’s no dedicated filter beyond the shared air intake filter that’s already clean?

    • A dirty condenser coil could be contributing to your frequent AC resets. It’s important to have it cleaned regularly to prevent overheating and ensure optimal performance.

      • Could you point me in the right direction? I’m new to understanding how AC units work, and I’m curious about the condenser coil. Would you mind describing where it’s usually located within the system and what it typically looks like? My main unit box looks clean, but maybe the coil is hiding somewhere else?

        • I understand you’re unfamiliar with AC units, and that’s perfectly okay! The condenser coil is an important part that helps your AC cool your home, but it’s located outside the main unit (the box you pictured). It typically looks like a set of thin metal fins, kind of like a car radiator, and can get dusty or clogged over time, which can cause your AC to overheat and trip the reset button.

          While cleaning the condenser coil is important, it’s more complex than simply wiping the outside box. If you’re not comfortable tackling it yourself, I wouldn’t recommend it. Instead, consider these options: Hire a professional technician: They have the tools and expertise to diagnose the problem and clean the coil effectively. This typically costs around $100 and includes a check to see if the reset issue has been fixed.

          Remember, ignoring frequent resetting can damage your AC, leading to costly repairs. Taking action now can save you money and keep your cool air flowing!

          I hope this information is more helpful and less discouraging. Don’t hesitate to ask if you have any other questions!
