Replace the evaporator fan if it doesn't run when activated.Ĭlean dirty condenser coils because dirty coils won't cool down refrigerant before it enters the evaporator, resulting in poor cooling performance. A failed defrost timer won't advance into the automatic defrost mode so the defrost heating element would never turn on to melt frost off the evaporator fins.Ī failed evaporator fan can also cause cooling problems because it won't circulate air through the freezer cabinet. A failed defrost bi-metal won't allow current to reach the heater so a failed defrost bi-metal will also inhibit cooling in the freezer. If the defrost heating element that melts frost off the evaporator fins fails, frost will cake up on the evaporator fins and interfere with cooling airflow in the freezer.
Problems in the automatic defrost system can also prevent the freezer from cooling and trigger the high-temperature alarm. If the freezer compartment is actually at 0 degrees when the high-temperature alarm sounds, a failed thermistor or bad electronic control board likely caused the alarm by inaccurately detecting freezer temperature. If the freezer cools but doesn't cool down to the set temperature, a failed thermistor may be inaccurately detecting freezer temperature or the electronic control board in the freezer may be inaccurately detecting the thermistor signal. This tactic won't work for all freezer models, but it may work for your freezer if you're desperate to keep food in the freezer from spoiling and can't get a service technician to repair the freezer right away.
If it rattles, try replacing the relay to get the compressor started and the freezer cooling again. Unplug the freezer and pull off the start relay and shake it. If the evaporator fan inside the freezer runs but the compressor doesn't run, a failed start relay on the compressor could be preventing it from starting. A service technician will need to diagnose and fix a sealed system failure because the repair involves the recovery and recharge of the refrigerant. Have a service technician examine the freezer if you suspect a sealed system failure. If the alarm goes off and you hear the compressor running, a sealed system problem such as a refrigerant leak or a failed compressor pump may be causing the problem. Restore power to the freezer by resetting the house circuit breaker for the electrical outlet and the freezer will resume cooling if a power failure caused the alarm. When you hear the alarm, check the freezer electrical outlet for power because the control uses a battery as back-up power to sound the alarm (on most models) when the outlet power fails.
(The exact temperature rise that triggers the alarm varies by model.) So far I love this freezer and highly recommend it.The high-temperature alarm sounds when the temperature inside the freezer rises 15 degrees above the set temperature so that you can fix the cooling problem and prevent food spoilage. The extra storage space makes allows me to keep only the items I need regularly in the freezer in my kitchen. The LED light in the lid was a bonus that I did not expect: it makes freezer searches much easier in the low light area it is located in. It has two hanging baskets with are large enough to be of real use, and it has a removable divider with allows a second side compartment to be formed this is where I put items I want to get at quickly, as well as jars for homemade soups and stocks. It is extremely quiet and keeps its cold really well I have seen almost no frost, unlike my previous freezer. I found this Magic Chef 5.0 cu ft freezer at the local HD and it fit the bill perfectly: it was a little wider than my previous freezer (about 5 inches) but the other dimensions were the same, and with that extra width I got almost double the storage. It was always crammed with foods I wanted to get a bigger one but I had a limited footprint. My old 3.1 cu ft chest freezer up and died suddenly so I had to replace it quickly.
