Ensure your Line (L1) and Load (T1) connections are torqued to specification. Loose terminals are the #1 cause of localized overheating. If the plastic casing near the terminals looks discolored, high contact resistance is your culprit. 2. Why is your GMR32B running hot?
To prevent "hot" failures and extend the life of your controller, follow this quarterly routine:

If your environment exceeds 40°C (104°F), derate the maximum current by 1.2% for every degree above that threshold. 3. Interpreting Manual Fault Codes
The is a robust controller, but it is not "set and forget." High heat is almost always a symptom of poor thermal dissipation or loose electrical junctions. Ensure your thermal paste is fresh and your cabinet is breathing, and the unit should return to stable operation. Ensure your Line (L1) and Load (T1) connections
The GMR32B must be mounted on a properly sized heatsink. Between the backplate of the controller and the heatsink, you must apply a thin, even layer of . Without it, an air gap acts as an insulator, trapping heat inside the SCRs. B. Inadequate Airflow
This guide serves as a technical supplement to the official GMR32B manual, focusing on setup, wiring, and resolving heat-related issues. 1. Core Specifications & Setup focusing on setup
Phase angle controllers naturally generate heat as a byproduct of switching efficiency. However, "too hot" usually stems from three areas: A. Lack of Heatsink Compound
