My whirlpool frbb36af20 2 frdge freezer has stopped working , the freezer defrosted itself and you cannot adjust the temperature on the display for the freezer as all it does is just flash two lines

Start a diagnotsics mode and enter test code 1 - 4 of the diagnostics to start the defrost mode

Self Diagnostics

To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display can be illuminated by pressing an adjacent temperature adjustment button. When both displays are illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all

4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and freezer displays will indicate that the refrigerator is in Self Diagnostic mode.

To perform a self diagnostic test, locate the test in Table 2, Diagnostic Tests.

For temperature control panels with single-digit displays, the COLDER temperature adjustment button will increment the numbers up and the WARMER temperature adjustment button will increment the numbers down. Use the freezer temperature adjustment buttons to enter the test code number in the freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in

the refrigerator display. When a test code has been entered, the displays will flash to confirm the test.

Press the HOLD button for 3 seconds to begin the test.

For temperature control panels with 3-digit displays, the COLDER temperature adjustment button will increment the numbers down and the WARMER temperature adjustment button will increment the numbers up. Use the freezer temperature adjustment buttons to enter the test code number in the freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in

the refrigerator display. When a test code has been entered, the displays will flash to confirm the test code. Press any button other than a temperature adjust button to begin the test.

When testing has been completed, do one of the following things:

• Enter code 1 5 to completely reset the system.

• Enter code 1 6 to exit diagnostic mode. The temperature control panel is reset automatically.

• Unplug the refrigerator for at least 10 seconds. Test mode will terminate when the refrigerator is plugged back in.
Test mode will terminate automatically after 15 minutes of inactivity.
(or in your case.... after the deforst cycle completes and possibly + 15 minutes)

You need to cycle your freezer display to indicate 0 and your refrigerator display to 7.

Control and Sensor System Self-Test (0 7)

This test checks all five thermistors located throughout the unit. Once the test is initiated, the test code (0 7) will stop flashing and the thermistor test results will appear on the freezer display in the test order listed below. The thermistor test sequence number will not be shown on the display.

If the unit is not equipped with the Quick Chill option, the third thermistor (quick chill) will display a 0 and 3 audible beeps will sound at the temperature control panel. This is not a failure if the unit is not equipped with the Quick Chill option.

Thermistor test results:

• P = Pass

• 0 = Failed

• S = Short to 5 VDC

• B = Bad amplifier

Thermistor test sequence is:

1. Fresh food top thermistor

2. Fresh food bottom thermistor

3. Quick chill thermistor (displays 0 if unit is not equipped with Quick Chill option)

4. Evaporator thermistor

5. Freezer thermistor

Note: Thermistor test results will be displayed in the sequence shown above. The thermistor test sequence number will not be shown on the display.

Note the failures if any. Should ANY of thermistors fail you must replace it.

Having said that... at this point your stick with doing a manual defrost by unplugging the unit and directing a fan into the compartment for just over 2 hours to make sure ALL of the ice on the coils and in the drains has melted. (Yes it makes a water mess!)

After the manual defrost restart the unit / plug it in and once the compressor starts listen for the evaporator fan when the door switch is actuated and the condenser fan in the bottom of the unit any time the compressor is running. If either of the fans are not running you must find out why. Can be a door switch, motor winding or power to the motor. The door switch does not affect the condenser fan.

Finally if the unit is not automatically defrosting due to a component failure... i.e

Heater, themistor, or wiring you will see ice build up again in 2 to 3 days again and you will have to keep going through the manual defrosting routine until the automatic defrosting problem is resolved.

Hi,

Check out these tips...they can help you figure out whats going wrong with yourrefrigerator and why it is not cooling

How to Defrost Refrigerator Defrost Timer Problem

I had a same problem, However the fan in the freezer seems stop and the freezer compartment is melting. Its a double door LG with 270 ltrs.

Turn the freezer off and let everything thaw. Download an electrical schematic from the Whirlpool web site and check the defrost circuit including the timer.

Hi, you have a common problem with your control boards; there is a cheap fix if you can use a soldering iron or you can have your modules repaired.
Let me know

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp ..


If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

Modern fridge/freezers are built to automatically defrost themselves. To do this they require that the room temperature is well above freezing to allow the defrost to take place. If you site the freezer in too cold an environment it is unable to defrost itself and will eventually stop working. It sounds strange but if it is too cold the freezer cannot work. The solution is to buy and fridge/freezer that does not automatically defrost itself if you want it to work in a cold environment.

take back panel off inside freezer. check continuity thro heater and thermal fuse in series with heater

Temperature control may have failed. Thermostat causes compressor to cycle on and off with temperature in the refrigerator section. If the compressor is not trying to run and is cold to the touch no power is getting to it. compressor is located in back on the bottom.

Additionally the defrost timer may have stopped working while in the defrost position. Locate the timer and rotate the clutch head screw clockwise a small amount and if the compressor starts and runs replace the timer.
