Just thought of another "issue".
If the air inlet is plugged and the fan is on other than high speed,
there is insufficient airflow past the resistor pack to keep it cool,
so it is more likely to burn out.

Again, the SAFE way is to ALWAYS start with the fan on high. It does
more for your defrost that way anyway, so why not??
