    The minus 33 means that the freezer has not gone into defrost and is froze up the evaporator coil. Turn your energy saver off and turn the machine off. wait ten seconds and turn on.  Machine should now go into defrost for about 15 minuets. If it now gets a E code, Ohm out the thermistors. If it never defrost’s,  You need to check the heater control relay and the heater wiring.  You can ohm it out at the controller. When without power before repowering.  Then check for voltage at repower to the heater.
