No.     ;-)

If outside temps are below 70, the fridge should stay
cold or very cold.  The fans should never come on.
The aluminum fins should be below freezing.

I set my thermostat at about 9-10 o'clock position and
my internal temp will go to 32 or just below at
night.  With the thermostat at max, it will go down
into the low 20s overnight.

Maybe your thermostat is not working properly
or your flame is too weak from the orifice or from
low propane pressure.  Worse case, the ammonia
chemicals have caked up.  See:

for more about this and troubleshooting.

FWIIW:  I didn't have success with a pair of Radio
Shack computer fans.  The fans ran much more--I mean
MUCH more--than the old stock fan, and the fridge
got warmer in the hot afternoons.  I put in a Volterra
replacement and now it behaves as before--the fan
cycles on/off frequently on a hot afternoon, rather
than running steady from 10am to 7pm.  I don't know
if the computer fans really don't move enough air, or
if the pair had an interference pattern that didn't
move the heat from the fins.
