Question about GE Monogram ZISS420NRSS 42" Built-In Side-By-Side Refrigerator (ZIS-S420NRSS, ZIS S420NRSS)
Defroster may not be working in freezer. drain tube is clear, but drain pan is empty. the pan is on top and almost looks like water flows uphill
could the defrost heater or thermostat be bad?
Defrosters are commonly controlled by a primitive timer and this may have a 'dry' and a 'wet' (humid) climate setting that will cause the defroster to cycle generally every 12 or 24 hours.
If set wrong (by accident or on purpose), it can allow too much frost to accumulate before attempting to defrost.
This can cause a gradual buildup of ice.
Also the heating element for the freezer may have failed open so it never heats at all. The connections that need to be checked are often buried between the in- and outside walls.
The timer is probably still OK since you apparently aren't having a problem on the refrigerator side.
