If you can put the frig. in defrost this will tell the sensor to turn on and you will see the heater melting the ice,if you can't put it in defrost and the sensor still has ice on it,simply put it in your hand,as your hand warms up you should feel the sensor pop,this pop tells the heater to turn off,if no pop the sensor is bad,if no ice on the sensor put it in a glass of ice,chill it down and do the same hand test,you can also use an omhs meter to check it,all the sensor does is open and close,let me know what you find-mike

Coils freeze up and fridge runs all the time till I melt coils.


There might be a few causes

Door Seal might be defective causing the door not to shut tightly this causes air from the room to get into the freezer through the opening and as the air comes in contact with the evaporator coils, it freezes. Normally the defrost system removes the ice but if the seal is defective the coils freeze too quickly and the defrost system cant keep up

If the freezer evaporator coils ice over, the defrost thermostat might be defective. Several times a day the defrost heater turns on for a few minutes to melt away any frost that may have accumulated on the freezer evaporator coils. In order for this to work, the defrost thermostat has to sense that the coils are cold enough. If the coils are cold enough the defrost heater will turn on. If the thermostat is defective it may not be able to sense the temperature of the coils and then won't turn on the defrost heater. If the defrost heater doesn't turn on, the evaporator coils ice over and eventually no air will be able to travel through the coils to provide cooling to the freezer. The defrost thermostat can be checked for continuity. It should have continuity when it reaches the low temperature of its operating range.

What is er dh?


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.

The coils keep freezing up.


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.

501f freezer ices up the evaporator. After defrosting it works well until it ices up again.


Could be a couple of things. First measure the resistance of the defrost heater that is mounted on the evaporator coil in freezer compartment. Make sure to disconnect the power from freezer first. The disconnect the defrost heater and measure with ohm meter. It should measure in the 20 ohm range. If it measures as "open" replace the coil.

Next suspect is the defrost timer mounted in the front of the compressor compartment. If the heater coil is OK, I'd just replace the timer. It is tough to test.

Finally, there is a defrost termination sensor mounted on the top of the defrost heater that shuts off the defrost heater when it reaches a high temperature. If the coil tests OK, and you are going to replace the timer, you may want to replace the sensor too. It is awkward to test, the temperature of the sensor needs to be be below room temperature to close. The cost of the sensor is low enough that you may not want to replace the timer, then test the system, and then have to go back in to replace the sensor later.
