Service Diagnostics and Procedures

Cutter-Grid

The cutter-grid is used to cut cubes from the ice

slab formed on the evaporator. It uses low voltage,

12VAC from the transformer, to heat the wires.

Wires are warm to the touch of a hand when not

under the load of a slab of ice. The cutter-grid is on

only from the start of a harvest cycle to 35 minutes

from the start of the production cycle (see page 11,

Operation–Selector Switch in "ON" Position).

There is no electrical repair for the cutter-grid. It

will have to be replaced as an assembly. If mineral

deposits have built-up on the cutter-grid wires or

frame, use ice machine cleaner to remove these

deposits and to improve cutter-grid performance.

To electronically test the cutter-grid

•

Check the resistance at the cutter-grid's plug

on the outside terminals (NOTE: The middle

terminal is not used). If the resistance between

the terminals of the plug is 5.0-5.9 ohms, the

cutter-grid is good. At any other resistance

readings, it will need to be replaced.

•

Check for continuity between terminals and the

cutter-grid's stainless steel frame. If continuity

is found, check for wires that are not on the

insulators.

Removing Cutter-Grid

1. Remove the escutcheon panel from inside the

unit.

2. Unplug the cutter-grid from the receptacle on

the side of the liner (see Figure 19).

3. Remove the four screws that secure the cutter-

grid to the liner (see Figure 19).

4. Remove the cutter-grid.
