C. MTS Cover Switch
The MTS cover switch feature is
designed to prevent the MTS gear motor
from being accidentally activated. It is
essential that the proper operation of this
switch be verified on a routine basis. Use
the following instructions to test for proper
operation:
NOTE: Freezer should be cleaned
and disassembled for this test.
1. Be sure all switches are in the “OFF”
position.
2. Remove the MTS cover to expose the
roller assembly.
3. Turn MTS switch to “ON”.
4. Look at the MTS rollers; they should
NOT be rotating. If they are rotating,
turn “OFF” mix switch and discontinue
use until repairs can be made.
5. If there is no movement, slowly install
cover and listen for the gear motor
to turn on. The cover should be
almost completely closed when the
gear motor turns on. DO NOT insert
fingers or objects into roller cavity
during this test. If the MTS does not
operate as described here, or you
are unable to determine if the MTS is
operating properly, turn the switches
to the “OFF” position, disconnect the
main power supply and contact your
service technician or the factory. DO
NOT place the freezer in service until
the problem has been corrected.
