How would that accomplish the goal?

I haven't see a mechanical drawing or
pictures of your particular fridge
but I'm guessing that there is a
housing in the top of the refrigerator
compartment that contains a thermostat,
defrost timer and perhaps light bulb.
The housing has openings that allow
the air to circulate around the thermostat.
The slight heat produced by the heater
is enough to raise the temperature around
the thermostat to trick it into running
the compressor for a longer period of time.
It's not necessary to increase the temperature
of the whole refrigerated box, just the
temperature around the thermostat.
