Removal
1.
Disconnect power, water line, and drain line. If a drain pump is used, it will need to
be disconnected and removed.
2.
Remove the access panel and rear panel (see figure 3.3)
3.
Remove the grille by removing the two screws and disconnecting the three wires to
the rocker switch. Be sure to mark where these wires go for re-assembly.
4.
Remove the drain valve.
5.
Remove the water valve.
6.
Take out the two screws that secure the top of the electrical bracket located in the
front of the mechanical area (see figure 3.4).
7.
Remove the six screws that secure the base plate to the cabinet on the bottom of the
unit (see figure 3.5).
8.
Gently slide the mechanical out the rear of the unit enough to gain access to the
condenser fan (see figure 3.6).
9.
Remove the two nuts that secure the condenser fan.
10. Disconnect the neutral white wire lead (black ribbed wire) at the terminal block and
the hot wire lead (black smooth wire) at the electronic control.
11. Remove the condenser fan.
Installation
Reverse the removal procedure for installation.
5.2 Thermistors
This unit utilizes two thermistors for reading temperatures for input to the electronic
control. Each thermistor has a different function for input to the electronic control.
Evaporator thermistor
The evaporator thermistor is made up of a stainless steel body and is secured to the under
side of the evaporator. The location of the thermistor allows the thermistor to give
voltage input to the electronic control. This input is processed through the electronic
control to switch the icemaker into the production or the harvest cycles. The thermistor
must be tightly secured to the evaporator bracket for proper heat transfer.
The following will happen in the event of a thermistor failure.
1.
If an evaporator thermistor fails, all loads will be shut off and the unit will not run.
2.
If the evaporator thermistor senses temperature outside of 0-140 deg. F, all loads
will be shut off and the unit will not run.
The thermistor can be checked by use of a multi-meter with the ability to read resistance.
To check the thermistor.:
1.
Disconnect and remove the thermistor from the unit.
