G. Removal and Replacement of Door Gasket

Remove old gasket by pulling it directly out of the vinyl gasket retainer. Thoroughly clean the gasket area with mild soap and water prior to installing the new gasket. The new gasket should be installed by assembling it at the corners first, then working toward the center at the top, bottom and sides. The arrow-shaped portion of the gasket should be firmly seated in the retainer groove for proper assembly. This can be checked by lifting the edge of the gasket and observing the engagement.

CAUTION

In order to get a proper gasket fit, it is important not to stretch gasket material during assembly.

H. Removal and Replacement of Defrost Heater

1)Turn off the power supply, and unplug the unit.

2)Remove the front panel, then remove the wire guard located below the display panel.

3)Unhook the wiring connectors at the control box, then remove the two hex-head M6 attachment nuts and the M5 bolt.

4)Very carefully slide out the refrigeration system. Support the evaporator as it clears the evaporator case.

5)Remove the connection lead wire for the defrost heater.

6)Remove the two 4×8 T2 evaporator shroud screws above each end of the defrost heater.

7)Carefully remove the defrost heater by twisting the ends together and removing the ends from the slots in the shroud.

8)Return the refrigeration unit to its proper position in the reverse order of the removal procedure.

9)Plug in the unit, and turn on the power supply.

CAUTION

Be careful when handling both the old and new defrost heaters. The heaters are sheathed in glass tubes and can possibly cause cuts if broken. Heater will also be hot after a defrost. Use gloves when handling. Avoid touching the glass directly; hold the heaters by the ends.
