A freezer stays cold by using a continuous refrigeration cycle that doesn't actually "make" cold, but rather pulls heat out of the compartment and releases it into the room. This is achieved through the constant circulation and phase changes of a specialized liquid called refrigerant.
A good starting point is the middle setting (for example, 3 or 4). You can use a freezer thermometer to check the temperature and adjust it gradually. Small tweaks are better than large jumps to avoid over-cooling and wasting energy.
Cold air sinks, so it collects at the bottom and, in a fridge freezer, the bottom shelves will be coldest.
If your Hisense refrigerator isn't cooling, the most common culprit is an airflow restriction caused by a blocked air vent or heavy ice buildup on the cooling coils behind the freezer wall. It could also be an accidental Demo Mode setting or a faulty part.
For the fresh food compartment, aim for 37°F, within a safe range of 32°F to 40°F. This range slows bacterial growth without unintentionally freezing items. For the freezer, set 0°F to keep foods thoroughly frozen and maintain quality.
For a 1–7 dial setting, set your freezer to 4 or 5 for the ideal temperature of 0°F (-18°C). On these dials, 1 is the warmest and 7 is the coldest. Setting it in the middle (4) provides optimal cooling for food safety while conserving energy.
Door or lid has been open for a long period of time or is opened frequently. This can change the temperature of the freezer. It also lets in excess moisture, which can cause frost build-up. Keep the lid or door closed as much as possible.
To reset your Hisense freezer, the most effective method is a hard power cycle. Unplug the unit from the wall outlet, or flip the circuit breaker off. Wait 5 to 10 minutes to drain the internal electronics and clear error codes, then plug it back in.
A freezer that stops freezing is typically caused by restricted airflow, a bad door seal, dirty coils, or a failing evaporator fan. These are the most common culprits and usually the easiest to troubleshoot yourself:
How to reset a refrigerator compressor
Putting a penny (or any coin) in the freezer is an easy trick used to check if your freezer lost power while you were away, and whether your frozen food is still safe to eat.
A freezer doesn’t actually "make cold"; instead, it works like an air conditioner by pulling heat out of the air inside and transferring it outside into your room. It maintains freezing temperatures using a continuous loop of pressurized fluid called a refrigerant.
The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.

The setting of 5 for both the fresh food and freezer section is the recommended setting for most environments.
To reset your freezer, perform a power cycle by unplugging the unit (or flipping its circuit breaker) for 5 to 10 minutes. This clears system errors and recalibrates the control board. For digital models, you can also reset the control panel directly.
A continuous hum is usually a sign your fridge is safely keeping food cold. However, it shouldn't run endlessly. Modern, energy-efficient compressors are designed to run 80% to 90% of the time to maintain consistent temperatures, but if the motor never shuts off, you may have an underlying mechanical issue.
Freezers typically last between 10 to 20 years, with an average lifespan of about 16 years. Standalone freezers tend to outlast standard refrigerators because they have simpler mechanics and are opened less frequently.
Most freezing issues are airflow-related, caused by a blocked vent, an overpacked freezer, a loose door seal, or ice on the evaporator fan. Dirty or failing components, like condenser coils or evaporator fans, can impact cooling fast and may require deeper troubleshooting or professional help.
To tell if a refrigerator compressor is bad, first listen for the "click-then-nothing" sound, check if the fridge struggles to cool, and feel the compressor to see if it’s excessively hot. You can definitively diagnose it by testing the electrical pins with a multimeter or checking the start relay.
On Hisense TVs, the physical reset button is usually a recessed "pinhole" located on the back panel (often near the HDMI and USB ports) or underneath the bottom edge. It is typically labeled simply as "RESET".
To fix a Hisense freezer that isn't working, start by performing a hard reset: unplug the unit for 5 to 10 minutes to clear electronic glitches, then plug it back in. If it still doesn't work, check the door seal, inspect the vents for ice blockages, and confirm it is set to the correct temperature.
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.
Be sure to check the electrical outlet, thermostat and airflow around vents. Cooling problems can also be caused by dust on condenser coils, faulty gaskets, clearance space around the refrigerator, a broken or stuck condenser fan or a faulty circuit board.
No, there is generally no physical reset button on a standard refrigerator compressor. Instead, the compressor relies on a built-in "overload protector" designed to automatically cut power if it overheats or draws too much current, and will reset itself once the motor cools down.
WHY IS MY FRIDGE NOT COOLING BUT MY FREEZER WORKS? If your freezer is cooling but your fridge isn't, there could be several reasons why, including: Faulty or stuck evaporator fan. Damper control may be stuck or in the closed position.
