Does your controller have a yellow PTC fuse? It’s known that in some cases when the ambient temperature is high, the resistance on the PTC fuse will rise significantly to block the current flow. The easiest solution is to use solder a wire across it to bypass the fuse. Let me know if this solves the problem.
