Fresh Food Overtemperature Thermostat - GEAppliances CFE28TSH Technical Service Manual

The defrost heater is a single-tube, glass-enclosed
radiant heater. It is held in place by two tabs on the
evaporator (one on each side), and by a ceramic and
wire support.
The defrost heater has an approximate resistance
value of 31 .
1. Remove the fresh food evaporator cover (see

• During defrost, the drain probe assists in
preventing the drain from icing closed. During
assembly, the probe must be installed on the
evaporator and inserted in the drain to prevent
drain freeze-up.
• A ceramic and wire support prevents the heater
from sagging and touching the metal drain
trough if the glass is broken.
2. Remove the ceramic and wire support, and the
drain probe from the evaporator.
