2. Control Board

1. Fragile, handle very carefully.

2. The control board contains integrated circuits, which are susceptible to failure due to static discharge. It is especially important to touch the metal part of the unit before handling or replacing the board.

3. Do not fix the electronic devices or parts on the board in the field. Always replace the whole board assembly if it goes bad.

4. To prevent damage to the borad, do not touch the electronic devices on the board or the back of the board.

5. Do not short out power supply to test for voltage.

a) Location

The control box is located behind the "Top Grill Assembly". If you remove 7 fixing screws, the control box can be found.

- In operation, all output is off for 2 seconds.

- In 2 seconds, the buzzer sounds with 2 blinks at a 0.5-second interval.

- Then, additional 2 blinks of “℉/℃” follow at a 0.5-second interval.

- Model name blinks 5times.

- Every LED blinks 3 times at 0.5-second intervals.

- The cabinet temperature is displayed.

2. Initial Defrost Check < Type F > : BSF23T, BSF49T

- The temperature of defrost sensor controls operation

1) The compressor is on at 38℉(3.5℃) or above.

2) The defrost mode is on when every sensor is at 38℉(3.5℃) or below

※ The pre-cool mode is on 5 minutes after the defrosting mode is on.

Board Details

<Type R > : BSR23T, BSR49T

- The temperature of room sensor controls operation.

1) The compressor is on at 41℉(5.0℃) or above

2) The defrost mode is on below 41℉(5.0℃).

3 Freezer - Defrost is available at 5, 6, 7, 8, 9 or 10-hour intervals.

(The compressor stops operation for 5 minutes after it is off.)

- The compressor is turned on or off

depending on the room sensor temperature.

The default setting is 8 hours.

4 Refrigerator - defrosting every 5 hours

5 Defrost system - This process is to lower the inside temperature

- Freezer before the defrost heater is on.

1. PRE-COOL - When defrost begins, the pre-cool mode is on before the defrosting heater is on.

- The defrost heater is on if the cabinet temperature goes down to or below 17℉(-8℃) within 45 minutes.

- The maximum duration of the pre-cool mode is 45 minutes.

2. HEATER ON - When the D-sensor on evaporator reaches 51℉(11℃), the defrost heater is off.

- The defrost heater can remain on for up to 50 minutes.

- In case of a D-sensor error, the heater is in operation for 20 minutes. Then, it is off if the room sensor temperature is 28℉(-2℃) or above.

- In case of a defrosting or room sensor error, the heater is operates for up to 20 minutes.

- When the D-sensor does not resume the defrosting temperature even 50 minutes after the defrosting heater is on, the error code is automatically saved. ※ The pre-cool mode is off in case of a defrosting limit error.

3. Respite - When the defrost heater turns off, a 5-minute respite is given to stabilize the freezing cycle.

-Defrost heater, fan and compressor is all off.

4. FAN stop - When the respite is over, the fan stops operation for up to 5 minutes to prevent the heated evaporator air from entering inside.

- Only the compressor is in operation in this mode, cooling the evaporator and cabinet air.

- If the D-sensor temperature goes down to or below 14℉(-10℃) within 5 minutes,

the fan-stop mode is over and regular operation is available.

6 Defrost system - Defrost is available with the operation of the cooling fan.

- Refrigerator - In case of a refrigerator room sensor error, a 30-minute defrosting begins.

- In 30 minutes, the system checks the refrigerator room sensor temp'.

- Auto-return is on at a certain temperature. ※ If the set temperature is 30℉(-1℃) or below, the return temperature is 37℉(+3℃). If the former is 32℉(0℃), the latter is 41℉(5℃).

7 Cabinet heater - If the compressor-on temperature is lower than the ambient

control temperature, the heater is off.

- If the ambient temperature is 78℉(26℃) or above, the heater is on.

- If the ambient temp' is between 78℉(26℃) and the compressor-on temp', the heater is turned on and off every 10 minutes.

- If the RT temperature is lower than the compressor-on temperature, the code heater is off.

8 Refrigerator - When the compressor is off, the evaporator fan is off.

Prevention of - To prevent the refrigerator evaporator from over-frosting, over-frosting the fan starts operation irrespective of the compressor-on

system or –off temperature if the inside temperature is 32℉(0℃) or below.

9 Door - Door opening: the door-open lamp blinks

- 5 minutes after door opening, the buzzer sounds and the lamp blinks until it is closed.

10 Evaporator - The fan starts operation when the compressor is on.

fan control - The fan stops operation when the door is opened.

- The fan is off when the compressor is off. (The fan starts operation irrespective of the compressor-on or –off temperature if the inside temperature is 32℉(0℃) or below.)

- The fan start operation 3 seconds after the door is closed.

2. Compressor Operation and Re-run Prohibition a) Compressor Operation

1) The compressor is not to be operated for 5 minutes after it is off.

2) Operation is to depend on the refrigerator and freezer sensor temperatures.

3) Operation is to depend on the preset difference. ( Ex) preset difference >±35℉(2℃): )

- The compressor is on at 35℉(2℃) or more above the set temperature and off 35℉(2℃) or more below the set temperature.

b) AC Load Sequential Control

1) Simultaneous operation is not available.

An operation starts 1.5 seconds later than another.

E. Compressor Protector

When a combined temperature/amperage value is above the limit specified by the compressor manufacturer, a protector will operate independently, turning off the compressor. The compressor will restart when this protector has reset. Note :

1. Compressor protector resets automatically.

2. If condenser fan is operating and the compressor is off, it is most likely that the protector has operated.

Ⅵ. Removal and Replacement of Components

A. Removal and Replacement of Compressor

IMPORTANT

lways install a new drier every time the sealed refrigeration system is opened. Do not replace the drier until after all other repair or replacement has been made. Install the new drier with the arrow on the drier in the direction of the refrigerant flow.

Note : When replacing a compressor with a defective winding, be sure to install the

new start capacitor and start relay supplied with the replacement compressor.

Due to the ability of the POE oil in the compressor to absorb moisture quickly,

the compressor must not be opened more than 15 minutes for replacement or

service.

1) Unplug the unit from the electrical outlet.

2) Recover the refrigerant and store it in approved container.

3) Remove the terminal cover on the compressor, and disconnect

the compressor wiring.

4) Remove the discharge and suction pipes.

5) Remove the hold-down bolts.

6) Remove the compressor. Unpack the new comoressor package.

7) Attach the rubber grommets of the prior compressor.

8) Place the compressor in position and secure it using the bolts.

9) Remove the drier, then place the new drier in position.

10) Remove plugs from the suction, discharge and process pipes.

11) Braze all fittings while purging with nitrogen gas flowing at a pressure

of 3 to 4 PSIG.

12) Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.

13) Evacuate the system, and charge it with refrigerant. See the nameplate for

the required refrigerant charge.

14) Connect the terminals and replace the terminal cover in its correct position.

15) Plug the unit back in.

Page 63

Page 64

B. Removal and Replacement of Evaporator

IMPORTANT

1) Unplug the unit from the electrical outlet.

2) Recover the refrigerant and store it in am approved container.

3) Remove the insulation tubing.

4) Disconnect evaporator inlet & outlet pipes.

5) Remove fixed screws and remove " cover evaporator."

6) Unhook all wiring connections to cover evaporator.

7) Remove the screws that secure evaporator.

8) Place the new evaporator in position and secure it using screws.

9) Remove the drier, then place the new drier in position.

10) Check for leaks using nitrogen gas ( 140 PSIG ) and soap bubbles.

11) Evacuate the system, and charge it with refrigerant. See the nameplate for

the required refrigerant charge.

12) Replace the removed parts in the reverse order of which they wer removed.

13) Plug the unit back in.

C. Removal and Replacement of Door Closer

1) Remove the top Grill assembly.

2) Remove the bolts at top hinge.

3) Open the door approximately 90°

4) Remove stopper door.

5) Insert the new door closer.

Note : When install door closer, Check door closer right and left

*Check right and left
