How much frost should be on freezer coils. You may be able to locate the culprit and be frost-free. Here’s what is causing that frost: Moisture can enter your freezer in a number of ways.
As you’ve probably discovered, when moisture comes in contact with the evaporator coils, frost can develop and limit airflow.
If the airflow is restricted, the freezer’s efficiency will decline; this may affect the quality of your stored foods (a condition known as freezer burn) and make them less tasty than before or give you less flexibility in storing other things for longer periods of time.

Sometimes, the coils are just clogged with a thin layer of ice that prevents it from getting colder even though the weather has gotten colder. When this happens, a defrost cycle comes in handy to unclog the pipes and let things flow smoothly. If you think something is wrong with your air conditioner, don’t be afraid to get professional help for correcting this.
Getting expert assistance will enable you to avoid future repair bills by providing quality maintenance service.
Defrost Timer is defective
The defrost timer turns on the defrost heater a few times throughout the day to melt any frost that may have accumulated on the freezer evaporator coils.
If the defrost heater doesn’t turn on, frost will continue to accumulate on the evaporator coils and they will eventually frost over.
In order for the defrost timer to turn on the defrost heater, the freezer temperature has to be above a certain reading as indicated by your freezer thermometer. So be sure it’s working properly and replace it if need be.
The defrost sensor could be damaged
Most modern freezers feature a built-in defrost cycle that automatically keeps frost from building up on the evaporator coils.
When the sensor detects ice starting to form on the evaporator coils, it temporarily heats those coils so that any existing frost will melt away.
Once the coil is clean again, the freezer switches back to cooling mode. If the troubleshooting methods explained above don’t do the trick and you still have problems with your freezer.
It’s time to consult with an appliance repair person who may need to replace your defrost sensor.
The defrost heater does not have continuity
The defrost heater turns on regularly throughout the day to melt away any frost that may have accumulated on the freezer evaporator coils.
If the defrost heater fails to turn on, frost will continue to build in thickness until it covers all of the evaporator coils and prevents air from flowing through.
To troubleshoot this issue, use a multimeter to check for continuity in the defrost heating element. Replace the defrost heater if there is no continuity in the heating element.
The poor freezer door seal
Over time your freezer door seals can dry and crack, which allows warm air to flow in–and cold air to go out. That’s why the seals need to be regularly sanitized with a multipurpose cleaner and dried thoroughly.
To double-check whether your freezer is working efficiently, put a bill halfway into the freezing unit. If it comes out easily, that means cold air is flowing out.
When you’re ready for new seals, find them at customer service or where you bought your unit. Installation instructions are included with the parts.
The gasket is faulty
The door gasket is an important component of a fridge. It prevents it from losing heat as well as keeping all the cold air inside trapped where it belongs, in your fridge.
When the door gasket becomes defective, humidity can penetrate into your fridge so make sure it is not torn or otherwise compromised.
Otherwise, you could experience strong temperature fluctuations that can upset the way food is stored in your fridge and affect its taste.
Also, if the door seal is not tightened properly and there’s a bit of cold air leaking out, you can end up wasting electricity when that little bit of cold escapes which means unnecessary bills too! So do make sure to check this part out to avoid any unnecessary energy wastage.
Problem with Defrost thermostat
The heating element inside of your refrigerator will turn on periodically to melt away any ice that may have built up at the back of your freezer.
Your refrigerator’s thermostat will activate the heating element for a set period of time, depending on how long it took for the coils in your freezer to cool off.
If however, you find that your refrigerator has no power or defrosting functionality, measure resistance across the thermostat terminals with a multimeter replacing parts in this way will help you if that’s required.
