The cause could be a failing door gasket. It could be letting in high levels of moisture which freeze around the coils. Also, a bad defrost element could also be causing this. If the defrost element does not turn it will allow too much ice to build causing this.
If you have too much food on the top shelf or on one of the other shelves, it can stop the air from sinking quick enough causing the top shelf to get too cold. Also if you turn the freezer colder, it affects how cold the air is that comes through the vent.
A freezer may not be cold enough due to user error, such as packing in too much food or not properly closing the door. However, sometimes parts to your freezer wear out over time and may affect your appliance's freezing capabilities. Some parts are simple to install as DIY fixes, but others need professional help.
The reason why the freezer is cold at the bottom is that cold air falls down. (It is heavier than warm air). So while the evaporator is very cold (freezing cold in fact) there is no air being blown across it to cool the entire cabinet only the air surrounding the evaporator area.
Faulty Evaporator Fan
If this fan isn't working correctly, the cold air won't distribute evenly, leading to a freezer that runs but doesn't freeze as it should. Listen for Unusual Noises: Strange noises can signal that the evaporator fan is malfunctioning.
The usual evidence of a clogged drain in a Side-by-Side Refrigerator is ice under the bottom basket in the freezer compartment in addition to a puddle of water on the floor. Built-In models and most Freestanding models require service to correct the issue.
A Frigidaire freezer not freezing is most often caused by dirty condenser coils, a worn-down gasket, or a faulty thermostat, which result in higher temperatures inside the refrigerator and inadequate airflow.
Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
Make sure the drawers/bins are at least 1/2 full. If the drawer has an adjustable temperature feature and items are freezing, adjust the drawer to a warmer temperature setting.
The air vents are blocked
This can be caused by storing too many items in either compartment. Blocking the air vents prevents the proper flow of cold air between the freezer and fresh food sections. To fix it: We recommend keeping your refrigerator about 3/4 full for the best results.
Ice buildup can mess with airflow, making only the bottom half cold. Here's how to keep things cool: Defrosting: Unplug the freezer and take everything out. Let the ice melt on its own or use a defrosting kit.
First, cut power to your freezer by unplugging it from the wall or shutting off power to the proper control panel switch. Then reset the freezer's control panel by lowering it to zero or using a shut-off switch. Consult your user manual for specifics on navigating the control panel.
Reasons your freezer isn't freezing may include:
Crowding items. Frost buildup. Dirty condenser coils. Malfunctioning evaporator fan.
Common Frigidaire Ice Maker Problems and Solutions
Check connection to water line, no kinks or blockages, and ensure water valve is open. Replace the filter if older than six months. Set freezer temperature to 0°F (-18°C) or lower. Replace the water filter.
Use the Reset Button or Crush Button on Your Frigidaire Fridge. First, check if your fridge has a Reset button on the control panel at the front of the fridge. Once you have located it, press and hold the button for 5 seconds. If there is no Reset button, press and hold the Crush button for 5 seconds instead.
On most modern refrigerators the drain tube and hole are usually located inside the refrigerator at the bottom in the back. To protect the hole, there may be a panel made from plastic that can be removed with a screwdriver. Once it is removed you'll be able to see the drain tube and drain hole.
If you've ever moved a fridge freezer, or even bought one brand new, you'll know that you are meant to give them time to settle once they've been put back down again. Waiting 24 hours before plugging in your fridge prevents compressor damage and ensures proper oil circulation.
The location of the reset button on your compressor can vary depending on the model and manufacturer. Typically, it is located on the motor or near the motor housing. Look for a small red or black button that is often labeled “reset.”
