I have a Kenmore Elite Refrigerator model # 596.78533801. The display panel is blank. If I press any button, all lights on the display come on as long as the button is held. Is it the control board?

Some do have a diagnostic mode and some do not. Each model is different and we really need to have a model# to help troubleshoot any issues. You also did not say what the issue is?

You can do this by:
Check the oven display to see whether the screen says "LOC." When "LOC" is displayed, the oven lock is activated and the door cannot be opened. You need to make sure it is locked so you do not mistakenly lock the door.

2 Press and hold the "Stop" button on the oven control panel until "LOC" disappears from the display. Some oven models have a button marked "Oven Lock," which should be used instead of the "Stop" button.

Lock the oven again by pressing and holding the "Stop" or "Oven Lock" button until "LOC" appears in the display

Klay421 --
Which model Kenmore Elite refrigerator do you have? If you have one of the older manual models, the thermostat is located inside the fridge side. If you have a newer model with digital controls you need to press and hold the the ON/OFF button for 2 seconds until the digital displays for temperature for the Freezer and Refrigerator lights. The Up/Down arrows allows you to adjust the temperature. If you are still having problems, write back. -- SWT

The Er DH error code indicates the temperature sensor on the evaporator coil did not reach 50 degrees within one hour.
This would indicate the control board did put the refrigerator through a defrost cycle.

This problem could be caused by a defective relay on the control board, a defective defrost heater, a broken wire to the heater, or a stopped up drain on the defrost pan causing ice to form on the evaporator coil.

Before replacing the control board, someone should remove the food from the freezer, remove the freezer drawer, and remove the evaporator cover to expose the evaporator coil, heater, and defrost sensor.
The voltage to the defrost heater should be 120 volts ac.
The defrost heater is part of the evaporator coil and is not replaceable as a separate part.

You can test the operation of the defrost system by pressing "Ultra Ice" and "colder freezer temp" for 3 seconds.
The first time you press and hold the buttons the board will test the compressor, fan, and open the damper.

All displays should be on.


The second time you press and hold the buttons the board will test the compressor, fan, and close the damper.

The third time you press and hold the buttons, the board will turn the compressor and fan off and turn the defrost heater on for around 25 minutes. This would let you know if the defrost system is working.

Need model number to help with this.

This advise is for Kenmore Elite and Whirlpool Duet front loader washers and dryers with a Control Lock problem.

This may or may not be an indication of a serious problem. In the majority of the cases, this is a simple operator error. Nearly all these model appliances have some sort of Control Lock feature on the front panel now. This is a designed safety feature that is used to prevent small children from manipulating the controls. The controls can be easily locked or unlocked by pressing and holding the following button on the front panel:

Whirlpool Duet Washer - Press and hold the END OF CYCLE SIGNAL button for 3 seconds.

Whirlpool Duet Dryer - Press and hold the END OF CYCLE SIGNAL button for 3 seconds.

Kenmore Elite Washer - Press and hold the DRAIN/SPIN button for 3 seconds.

Kenmore Elite Dryer - Press and hold the AUTO DRY LEVEL button for 3 seconds.

These instructions may not be all inclusive for all Kenmore and Whirlpool models, but they are the most common. Chances are, if you have a Control Lock feature, the instructions will be printed on the front panel adjacent to the button that is required to lock or unlock the controls.

NOTE: These instructions may also work for newer model Maytag, Hotpoint, Admiral and Fridgidaire model front loaders as well. Refer to your owner's manual or front panel for instructions pertaining to your sepcific model.

If the Control Lock feature will not lock or unlock the appliance, unplugging the unit for AT LEAST 30 minutes is recommended in order to reset the main control board. In many cases this is all that is required to correct momentary glitches.
