Amana Bottom Mount Refrigerator Operation, Mode a Functions Freezer or Refrigerator Temperature

Electronic Functional Description

Operation

Program mode has 2 submodes, Mode A and Mode B. Access to either mode is toggled with Display On pad. Entry in program Mode A is indicated with unmarked light glowing. Control is in program Mode B if light does not glow.

Mode A Functions - Freezer or Refrigerator Temperature

1.Choose freezer thermistor temperature display by pressing Freezer Temp pad. Freezer temp indicator light will glow. Temperature display will show thermistor temperature in binary coded decimal (BCD) format. Indicator lights 1 through 4 represent tens digit with 1 being most significant bit. Indicator lights 5 through 8 represent ones digit with 5 being the most significant bit. Indicator light 9 (coldest is + - sign; light glows signifying negative value).

2.Choose refrigerator thermistor temperature display by pressing Ref Temp pad. Refrigerator temperature indicator light will glow. Temperature display will show thermistor temperature in BCD as described above.

Electronic control value column is calculated in units of °F. Conversion is °C = (°F - 32)/1.8.

Mode B Functions

1.Door alarm delay can be adjusted from keyboard when in this mode. Press Alarm Off pad, door open indicator will glow. One temperature indicator should glow indicating present delay time setting. Pressing Warmer pad decreases delay by 1 and pressing Colder pad increases delay by 1. Delay times selected go from 1 to 9 minutes in 1 minute increments.1 being 1 minute and 9 being 9 minutes. Default door audio delay is 3 minutes.

2.Max Ref run time duration adjustment can be

performed in Mode B by pressing Max Ref pad. Max Ref light will glow. One temperature indicator should glow indicating present Max Ref run time duration. Pressing Warmer pad decreases Max Ref run time by 2 hours and pressing Colder pad increases by 2 hours. Times are from 6 hours (indicated by 1 temperature indicator) to 22 hours (indicated by coldest temperature indicator). Default Max Ref run time is 10 hours.

3.Max Frz run time duration adjustment can be performed by pressing Max Frz pad in

Mode B. Max Frz indicator will glow. Adjustment process is same as items 1 and 2. Duration times are in increments of 4 hours, ranging from 8 hours. 1 setting to 40 hours at coldest setting. Default Max Frz run time duration is 24 hours.

4.Refrigerator temperature offset is calibration adjustment. Temperatures at which refrigerator cuts-in and cuts-out are shifted by amount offset is set. Pressing Ref Temp pad while in Mode B causes refrigerator indicator to glow and 1 of 9 temperature indicators to glow. Pressing Warmer pad or Colder pad moves offset up or down range. Temperature indicators and offsets and what they imply are shown on chart below. The low voltage board freezer offset temperature is 0 and refrigerator offset temperature +2 from factory.

5.Enable freezer temperature offset by pressing Freezer Temp pad in Mode B. Freezer indicator will glow. Adjustment process, set point values, is identical to item 4.

INDICATOR	OFFSET
1	+8
2	+6
3	+4
4	+2
5	0
6	-2
7	-4
8	-6
Coldest	-8
