I utilized the HVAC Hero app to locate the manual and troubleshoot the issue, which provided me with a detailed description of the limit alarm and the necessary tools for verification. I plan to replace the pen limit switch to get the boiler back up and running. I encourage viewers to check their limit sensor wiring if they face similar issues. Overall, HVAC Hero was instrumental in guiding me through this process.
