What causes refrigerator temperature to fluctuate?
The vents or sensors are blocked Overfilling your refrigerator or blocking the vents with food is one of the most common causes of temperature fluctuations, and thankfully, it’s a very easy problem to solve. Within your fridge, there are numerous vents that allow warm air to leave and cold air to enter.
What are the symptoms of a faulty fridge thermostat?
Here are some signs that your fridge has a faulty thermostat and some troubleshooting tips to help you deal with them.
- The Refrigerator Is Not Cool Enough.
- Unusually Cold Refrigerator.
- Refrigerator Temperature Fluctuation.

Why would my refrigerator stop cooling and then start working again?
Be aware that it also may stop running simply because the correct temps have been reached in the fridge/freezer but should startup again if you leave a door open for a few minutes. Auto defrost usually occurs once every 8-12 hours so the compressor should be stopped at least 2-3 times per day.
How does a fridge thermostat operate?
The thermostat controls the cooling process by monitoring the temperature and then switching the compressor on and off. When the sensor senses that it’s cold enough inside a refrigerator, it turns off the compressor. If it senses too much heat, it switches the compressor on and begins the cooling process again.
Why is my fridge sometimes cold and sometimes not?
Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won’t have a fan). To do this, unplug the fridge and pull it out. Clean the fan blades and spin the fan by hand to see if it’s stuck.
Why does my freezer temp go up and down?
As said, temperature fluctuations are quite normal and will occur to a greater or less extent in all types of equipment. The temperature rises and falls in the freezer due to the control that the freezer is equipped with. Based on the setting, the freezer will cool until it reaches a limit value.
What would cause a freezer to work intermittently?
Faulty Start Relay: The start relay on your freezer provides power to the compressor. This means if the start relay isn’t working, at best your freezer’s compressor will work intermittently – or as is more likely, not at all, meaning your freezer won’t freeze.
Why does my freezer only work sometimes?
Freezer Contents are Blocking the Evaporator Fan. Another reason your freezer is not working could be poor packing of its contents. Make sure that there is enough space under the evaporator fan, usually in the rear of the freezer, so that the cold air emerging from the fan can reach everywhere in your freezer.
Is it normal for a fridge to turn on and off?
If your fridge turns on and off on its own, it can be experiencing a problem with it overheating. This is directly related to the condenser coils. The condenser coils will be located either on the back of your fridge or on the bottom behind the access panel.
Why is my refrigerator not keeping things cold?
Why does my freezer get warm sometimes?
Clean the condenser coils if dirty. A failed electronic control board or a bad thermistor (also known as the temperature sensor) can also cause your freezer to warm up. If the thermistor doesn’t sense that the freezer is warm, the electronic control board won’t turn on the compressor.
How many degrees should a freezer fluctuate?
0 degrees Fahrenheit
The recommended refrigerator temperature settings are 37 degrees Fahrenheit in the fresh food and 0 degrees Fahrenheit in the freezer sections.
Why does my freezer not work sometimes?
If your freezer is not working, the first thing to check is if the shelves are packed too tightly. Overstuffed freezers can cause airflow blockage especially when the evaporator fan is blocked. If your freezer is not cold enough, we recommend clearing off your freezer shelves.
Why does my fridge freezer turn on and off?
Thermostat. An incorrectly adjusted thermostat can cause the freezer’s compressor to start and kick off. The compressor provides the power behind the cooling function of the freezer. The inside temperature of the freezer determines when the thermostat sends the signal to power the compressor.
Why does my fridge stop working sometimes?
Typical causes are: 1) the door is left open frequently, 2) the condenser coils need cleaning, 3) the door doesn’t seal against the refrigerator box, 4) the cold control is set too cold, or 5) something is blocking the flow of cold air inside the fridge.
What are the functions of a fridge thermostat?
A refrigerator thermostat has only one function — controlling the refrigerator’s cooling system by turning it on or off to ensure that the temperature inside the fridge stays in the correct range of 33 to 40 degrees Fahrenheit. In frost-free models, a separate thermostat with a timer controls the defrosting cycle.
What happens when a thermostat fails on a refrigerator?
Thermostats allow you to turn a knob to adjust the interior temperature but a failing thermostat won’t be able to keep your fridge in the correct temperature range no matter how you set it. The unit will either keep the refrigerator running too long, causing cold food to freeze.
Why is my refrigerator temperature control not working?
Maybe the thermostat dial was bumped by a milk jug or somebody’s tiny fingers wanted to tinker with the tech. If the refrigerator temperature control is not working, then you may need to replace your thermostat or have a service technician pay a visit. If the Thermostat Works, Then…
How does a refrigeration system work?
The unit also includes a microprocessor that compares the sensing element’s readings to the desired temperature setting. The microprocessor then sends a command to the refrigeration system to turn on to lower the temperature and turn off when the temperature is sufficiently low.
