SKOPE Reflex Underbench Fridge and Freezer
Evaporator
Probe
The evaporator probe is located within the evaporator coil. It controls the refrigeration system
defrost initiation and termination.
If the evaporator probe fails, the defrost element thermal fuses may activate due to prolonged
defrosting. Due to this, if you replace the evaporator probe, you must check the resistance of
the thermal fuses and replace them if required (see Procedure 21, on page 41).
Procedure 26: To replace the control probe
Before you start
Make sure you take note of the original control probe cable’s path, e.g. a photo.
1. Remove the cartridge from the cabinet (see page 31).
2. Gain access to the evaporator fan assembly (see steps 2 to 3, Procedure 20, on page 40).
3. Carefully cut cable ties to release the probe cable. Detach the probe from the evaporator
assembly, trace back to its connector and unplug it.
4. Replace the probe. Following the same path as the original probe, fit the new probe with cable
ties as necessary. Ensure the probe cable is securely connected and cable tied in place.
5. Reassemble and test for correct operation.
Procedure 27: To replace the evaporator probe
Before you start
Make sure you take note of the original evaporator probe cable’s path, e.g. a photo.
1. Remove the cartridge from the cabinet (see page 31).
2. Gain access to the evaporator fan assembly (see steps 2 to 3, Procedure 20, on page 40).
3. Carefully cut cable ties to release the probe cable. Carefully separate the coil fins around the
probe, withdraw the probe from the evaporator coil, trace back to its connector and unplug it.
4. Replace the probe. Following the same path as the original probe, fit the new probe with cable
ties as necessary.
5. Ensure the probe is put in the same location (between the 4th and 5th fins), secured in place with
the evaporator fins, and that the probe cable is securely connected and cable-tied in place.
6. Reassemble and test for correct operation.
