Operation of Electrical Control Components

Freezer and Refrigerator Modules

The modules, when selected by the rocker switch, control the temperature of the unit by an internal thermistor mounted on the circuit board. Each module has an individual service mode.

Each module has the following connections to the rear of the circuit board:

1= Neutral

 

2= Not Used

 

3= L1

 

4= Compressor

 

5= Defrost Thermostat

 

DPDT Rocker Switch

L1

The DPDT Switch is connected to the household power

DPDT

supply with L1 connecting to terminal 2, and the Neutral

line to terminal 5. (See Figure 3-3)

Switch

 

In refrigerator mode, The DPDT switch will have the a

Nuetral

closed condition between terminals 5&4, and 2&1.

In freezer mode, The DPDT switch will have the a

 

closed condition between terminals 5&6 and 2&3.

 

Ambient Thermostat

 

The ambient thermostat will close at 35°F (1.6°C) and

Figure 3-3. DPDT Switch Arrangement

will then supply power to terminal 6 of the fan relay.

 

(See Figure 3-4)

 

Fan Relay

 

 

 

The purpose of the fan relay is to direct power to the

auxiliary heater and fan motor when ambient temperatures

go below 35°F (1.6°C) and the DPDT switch has

 

refrigeration selected.

 

 

Use an ohmmeter to test the fan relay. The following

conditions should result with the fan relay in the OFF state:

6

Between terminals 7

& 8 should read 4.4k Ohms.

7

8

Between terminals 6

& 2 and 5 & 1 - closed condition.

Between terminals 4

& 6 and 3 & 5 - open condition.

 

 

When voltage is supplied to terminal 6 through the ambient thermistor, voltage will come out terminal 2 and connect with terminal 1.

Terminal 1 is connected to terminal 5 which feeds power to the evaporator fan motor.

The following conditions should result with the fan relay in the ON state:

Line voltage is supplied to terminals 7&8.

Between terminals 4 & 6 - closed condition.

Between terminals 6 & 2 - open condition ( cutting power to the auxiliary heater).

Between terminals 3 & 5 - closed condition (supplying line voltage to the fan).

Between terminals 5 & 1 - open condition
