6.3 Replacing Lamps
Inspect the lamps daily to ensure that all lamps are functioning properly and replace poorly lit or
flickering lamps to ensure unit performance. The frequency of lamp changes will be determined
by application.
To remove the lamp fixture and access the lamp tube:
1. Identify the tube(s) to be replaced.
2. Turn the power to the chamber OFF. Refer to Section 6.1 Disconnecting the Power
before Maintaining or Servicing the Chamber on page 28 for instructions to turn off
the power.
3. Unscrew and remove the power connector from the receptacle of the fixture assembly
containing the lamp to be changed (Figure 6-1).
4. Use a Phillips screwdriver to loosen the top and bottom bracket screws (Figure 6-2).

The following instructions show the steps to remove one of the door mounted lamp
tubes. The steps are the same to remove the rear mounted tubes.
Remove all the trays and shelves before accessing the rear lamps.
Warning: Burn hazard
Do not touch the ends of the lamp tubes. Fluorescent lamps operate at high
temperatures and represent a burn hazard.
The LED bulbs and the fluorescent bulbs are physically similar with the same sockets.
When replacing lamps, ensure the original lamp is replaced with an identical lamp
with the same part number and markings.
Do Not Disconnect Under Load
Shut off the power to the chamber before disconnecting the power connector from the
receptacle.
