Frank, although the refrigerator is probably frost free (automatic defrost) there are a few reasons that the defrost cycle would fail. The defrost bimetal thermostat that controls the defrost cycle can fail. This bimetal is closed and opens to stop the defrost cycle when enough heat is given off. I do not know about the Jenn Air, but I think most refrigerators use a similar strategy. A second problem that is possible is the defrost timer fails (or the wires that run it). Defrost may be a daily function. Another possibility is a bad defrost coil or connection to it. Those are the 3 major components of defrost cycles.

You will have to manually defrost the freezer to prevent spoiling food. If you have to defrost regularly then one of those components is probably bad.

In general, not directly related to frost build up: Keep the refrigerator freezer section clear around the air grilles (not stuffed and no plastic bags that block air flow). If the refrigerator coils in back (freee convection) or underneath (forced convection) are really dirty, then cooling will also be a problem (but probably not related to frost buildup).

Why does the freezer seem to be at a higher temperature than indicated?


Check the back inside wall of the freezer for s coating of ice/frost or snow like substance. If yes-- that is an indication that your auto defrost system is not working. As the frost builds up more, the temp inside will get warmer. Most common problem in the defrost system is a burned out heater behind that back wall, but could be several problems causing it.

You mean the temps are getting warmer? Look inside the rear of your freezer and back wall and tell me if you see snow or a layir of frost building. If so pull everything and unplug and do a manual defrost a hair drier will speed things up.Sounds like we need to use the tech sheet here but Kitchenaid will not allow me to publish here.

Frig has suddenly become warmer than usual. Freezer is at 20 degrees and frig at 60. Tried to vacuum coils but very dificult to reach them underneath the unit. Any other hints?


what the problem most likely is a failed part of the defrost system Do you see a bunch of frost built up on the back wall of the freezer? If you do frost build up, take off the back wall of the freezer and replace the defrost heater and defrost thermostat. A hair dryer could be used to melt the built up frost from the coil behind the back wall. Another part that will cause frost build up is the defrost control, that isn't the freezer behind the back wall but instead it is part of the main computer board on the back of the refrig. I would replace heater/defrost thermostat first though, since they are the most likely to fail parts.

I hope my answer will help you to fix your refrigerator,

Usually, the freezer knob just adjusts the airflow from the freezer to the freshfood section. The refigerator control turns the unit on and controls temperature. When unit is running, do you hear the fan running in the freezer? The fan forces air to the refigerator section. If not, probably bad fan motor. If it is, do you see frost build up on the back wall of freezer section? If so this would indicate a defrost problem, ice build up on evaperator blocking airflow to refrigerator section. You cleaned the condenser, Was the condenser fan running? Defrost causes. Defrost thermostat, heater,defrost timer. Good luck.

I have a Samsung refrigerator/freezer How do I adjust the freezer temperature?


Hello,


1Place the appliance thermometer in a glass of water.

2Set the glass of water with the thermometer in the refrigerator on the middle shelf.

3Check the temperature on the appliance thermometer after 24 hours.
The temperature should register between 37 and 40 degrees Fahrenheit (2 and 4 degrees Celsius) in order to store food safely.

4Look for the temperature control dial inside the refrigerator if you have to adjust the temperature, and make it warmer or cooler.
If you can’t easily see the control dial, check the owner’s manual for a diagram that shows the location
When looking at the refrigerator temperature dial, you may see numbers rather than degrees. The majority of refrigerators use a set of numbers, with the lower numbers representing cooler temperatures and the higher numbers representing warmer temperatures.

5Move the temperature dial in the necessary direction to adjust the temperature up or down. Be sure to move the dial only one number in either direction because it probably will not take much to change the temperature in the refrigerator.

6Adjust the temperature balance control if your refrigerator has such a dial or sliding switch. This allows you to direct more or less cold air to the refrigerator section from the freezer section.

7Wait at least 24 hours, and then check the refrigerator temperature again.

8Observe the amount of frost in the freezer section of the refrigerator if you are unable to properly set the temperature.

90Defrost the freezer if the amount of frost is more than .25 inches (.64 cm) thick.

10Repeat the steps as necessary until the temperature is within the safe range.

11Use a permanent marker to draw a line on the dial after you locate the best setting on the refrigerator temperature dial. This will give you a reference point in case your dial moves and needs to be adjusted in the future.

Hope this helpout...

Hi,

All the cooling coils for this model are in the freezer section. There is a fan down there behind the back wall on the top. This fan directs air up to the fresh food section.

Check the temperature of the freezer you can do this by inspecting the ice cream, if the ice cream is soft you are above 5 degrees F. If you have a good cold freezer then the problem is with air flow, the evaporator fan that I spoke of could be bad).

If your freezer temperature is not as cold as it should be you may have a defrost problem, look for any signs of frost build up on the back wall of the freezer section, if you see frost you will most likely need to put in a new control.

If the freezer temperature is warmer than normal and you do not have frost you may have a sealed system leak, this will require a technician for sure.

The freezer is 19deg and the lower food compartment only gets to 60deg


Model number is always valuable in order to be able to give you more accurate information.

Check rear wall of freezer by feel for frost. Heavy, even frost indicates likely problem in the defrost system. Defrost heater (most likely and in freezer behind rear wall), defrost thermostat (in freezer-must be checked at freezer temperature) or one of Defrost timer or Defrost control (Circuit board) generally located in Refrigerator compartment but may be inside rear of outer case. Defrost heater and defrost thermosts can be checked with an ohmmeter. Disconnect power to refrigerator, remove rear wall and disconnect at least one side of any component you are testing. If the heater and defrost thermostat test good for continuity then replace the defrost control.

Without repair refrigerator will work perfectly for about 7-10 days after being COMPLETELY defrosted, including behind freezer panel, until thick frost builds up again cutting off air flow to both compartments

Inside the refrigerator, the back of it ices up, the back of the top shelf and the coils behind the vegetable bins.


Make sure the vent from the freezer is set to a warmer temperature. You can also check the freezer to see if you see heavy frost. If no frost then try to adjust the vent

The fridge section of my LG GRB218JUDA has stopped working and the temperature indicator reads Err FF. Can you help


Side by side and other refrigerators are controlled or cooled by one system. Look to the freezer side for frost buildup on the back wall of the freezer. Frost buildup on the back wall of the freezer stops the air that cools the refrigerator from circulating. Frost on the back wall indicates a problem in the defrost circuit related to the timing device, heaters or defrost thermostat.

Freeaer and refrigerator warm


Check and clean the condenser coil in the back behind a removable panel. after cleaning make sure you replace the panel. Check the back inside wall of the freezer compartment for frost build-up. If there is frost on the back wall you have a defrost system problem.
