It is not hard to replace the heater. Just remove the access panel. Directions are in the repair manual at the link I provided. Gee a proud owner of a subzero oughta have a few dollars laying around to get an ice box repaired.

Can you post any pictures so I can at least see what I am talking about? Did you try to remove the access panel in the freezer to see if there was ice buildup?

Refrigerator problems




Water
is pooling up under the crispers: defrost drain is stopped up. When the
ice box defrosts the water has to go somewhere. If the drain is stopped
up then it will cascade down the rear walls of the ice box and pool up
under the crispers. Solution? Clear the drain using hot water, hair
dryer, shop air, remove the object blocking the drain. Door gaskets
that are worn or broken will allow for air to get into the ice box and
excessive moisture will build up.

Freezer is frosting up, fresh food section is warm: bad fan motor,
defrost drain stopped up and forming slab of ice between the freezer
and the fresh food section. Solution: check heaters and
terminator(defrost thermostat) unplug the ice box and let it defrost
completely. Clear objects from drain. Check timer. Note to find the
location of your timer look up your model number online here: APPLIANCEPARTSPROS.COM

Refrigerator dead: it may be that the defrost
timer has went into defrost and got hung up there. Twist the timer
around several times and it may start working till you can get another.
Refrigerator runs all the time: The thermostat is fried (internal contacts stuck together) replace it.

Compressor won't run: burned up relay. Remove the relay
from the compressor and shake it. If small particles come out or it
sounds like a salt shaker or there is no sound at all or it smells and
looks burned then it is bad. Replace it.

Freezer getting warmer freshfood not cool at all: Check under the
bottom for the fan motor to be running and the cob webs, dust, dirt,
and pet hair, off the condenser coils. If the fan underneath has quit
then the ice box won't get cold.

Everything is freezing over in the bottom and the top. Bad cold control.

Do I need freon? 99% of the time NO. Most of the time it is a
dirty coils problem or a bad fan motor, unless you have a leak. Since
the ice box only holds 4 ounces of freon it would quit cooling at all
in a short time if it had a leak.Their would be no halfway cooling, not
for long anyway.
