Install a cooling fan or ensure the heatsink fins are oriented vertically to allow for natural convection. C. Harmonic Noise and Overloading

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 Install a cooling fan or ensure the heatsink
To prevent "hot" failures and extend the life of your controller, follow this quarterly routine: Wiring Basics The GMR32B must be mounted on
If your heatsink has an integrated fan, ensure it is spinning freely and not clogged with grime.
Running the GMR32B at its absolute limit (32A) in a high-temperature environment will lead to thermal runaway.
