What you should do is change the door gasket.
You may temporarily fix it inflating the seal injecting silicone beneath, but it won’t last.
You can check the seal pushing a thin sheet of paper. If it goes in between, the gasket is not closing the gap.
The gap in the door could affect the temperature for short periods. On long periods it could be the thermostat.
A malfunctioning thermostat can also produce frost inside.
