Monitor, Display and Regulate Temperatures
The temperature signal from the thermistor in the refrigerator and/or freezer compartment is monitored by the micro-
processor, and displayed on the LCD. Though the compartment air temperature does fluctuate, the LCD displays
the average temperature. (See Figure 3-11) When the compartment temperature reaches high offset, the signal is
sent to the compressor relay on the control board to close. This allows power to be supplied to the compressor and
evaporator fan, which cycle on. (See Figure 3-12) As the compressor and evaporator fan run, the compartment tem-
perature drops. When the compartment temperature reaches low offset, the signal is sent to the compressor relay
on the control board to open. This interrupts power to the compressor and evaporator fan, cycling them off.
NOTE: If the compartment temperature should ever exceed either the high offset or low offset (for example: when a
door is left open), the temperature displayed on the LCD will change by one degree per minute.
