Not sure how old it may be, but you can check a few things to see if it's defrosting properly. Also clean the condenser coils under the refrigerator to insure good circulation of air over coils. In the picture below you will need to check out three things until we find the problem. Defrost timer, defrost heater, and defrost thermostat. Let me know when your ready, Sea Breeze

Fridge and freezer at 50 degrees with settings on max cold. I can hear compressor cycling and all power is on. Suggestions?


Your Refrig/freezer should be set as follows:

Refrigerators: 36 to 40 degrees. Ideal temp is 37 Fahrenheit. Note: A temp above 42 degrees promotes bacteria.

Freezer: temp should be -5 to 6 degrees Fahrenheit. Ideal temp is 0 degrees.

Then check the door seals around the edges to see if any splits, tears or cracks have messed up the seal. This will cause your compressor to constantly run as it's trying to cool off the warm house is being sucked into the freezer (or Refrig). A sure sign the door seals are damaged is lots of ice in the freezer door area or water pooling in the bottom area of the refrigerator.

Wait about 4 hrs after you readjusted the Refrigerator/Freezer settings so everything settles down. If you still have problems then the coolant may need to be serviced (topped off) or the motor serviced/checked.

Don't procrastinate because a water heater and Refrig/freezer are the 2 largest energy users in your home- they run 24 hrs a day.

Hope this helps...

Freezer and fridge not cool enough


Check if the syrofoam pieces block air inlet. If so then this may be the problem.

Freezer in the gararge redfrigerator quits working when outside temps get real cold


hello. this is a common problem. The thermostat for a refrigerator/freezer is in the refrigerator part. Normally the refrigerator is kept at around 40 degrees. The compressor turns on as required to maintain this tempearture. The evaporator coils are concentrated in the freezer side, so that the freezer stays at around 0 degrees while the fridge side is held at 40.

If the ambient temp is around 25 degrees, the refrigerator compartment will get below the setpoint of 40 degrees, and gradually continue down towards 25 degrees. The compressor will not have to run at all to maintain this. In fact, the compressor is designed not to run, once the refrigerator compartment gets below the setpoint, for fear of freezing the contents of the fridge.

The lack of circulating refrigerant due to the non-running compressor means that the freezer compartment will gradually warm up to 25 degrees.

If the unit were just a freezer, it would work fine in the unheated garage. If it were just a refrigerator, it would not run in these conditions, and the contents would eventually freeze, but it is otherwise OK.

first of all switch off your refigerator for about 8 hours.. than again switch it on. now place your thermostart at 4. now let it run for about 2 hrs...... after that also if your refrigerator won't decrease its temperature than please replace the blower inside it........... or else contact your service authority.

Amana bottom freezer refrig runs at maximum coolness


Thanks for your inquiry. I think I may have fixed it. I unpluged it and took everything out of the refrigerator and freezer, cleaned it thoroughly inside and out and unscrewed the back wall inside the freezer. There was a huge ice buildup on the coils so I let it sit for 12 hours like a defrost. I turned it back on and it seems to be working fine. It is not running constantly and is maintaining about 5 degrees below. If this doesn't stay working, I guess I have to call a repairman.

WHIRLPOOL NO-FROST REFRIG/FREEZR MODEL-EHT201ZKWR5


looks like operating normally...

the fridge as it reaches it's temperature shuts the compressor off and then after a few minutes..the fridge would increase temperature again and would turn back the compressor again.

its the thermostat which is cutting on and off the compressor.

and i think it is normal. based on the temperatures that you indicated..it is cooling very well..0 F in the freezer and 40 in the refrigerator... that's good.
