In one paragraph
Before anything is condemned on a Chill by Hisense refrigerator, it is worth separating two different faults that look identical from the front: air that cannot circulate inside, and heat that cannot leave at the back. That puts a defrost cycle that has stopped clearing the evaporator at the top of the list here and a temperature sensor reading wrong at the bottom.
What owners actually report
- The outside of the cabinet or the rear grille is hot to the touch — Warmth is normal.
- The refrigerator side is warm while the freezer is fine — One compartment failing alone is an air-path symptom, not a refrigeration one.
- NEAR MISS — the display reads correctly but a thermometer disagrees — That is a sensor or control question, and it belongs on the controls page.
Likely causes on this kind of machine
- A defrost cycle that has stopped clearing the evaporator — Ice builds on the coil, air can no longer pass through it and the cabinet warms while the compressor runs harder than ever. It leads on this platform because the parent range uses adaptive defrost, and adaptive defrost stalls quietly — the cabinet warms weeks after the ice began.
- Blocked return air or a stalled evaporator fan — Cold air has to circulate. Shared refrigeration hardware in a smaller cabinet means the air path is shorter and less forgiving of a blocked vent.
- A damper or diffuser stuck shut — The flap that meters cold air into the fresh-food compartment can stick, leaving one side cold and the other warm with nothing else wrong. Air distribution decides what the owner feels, so a blocked path outranks the components behind it.
- A temperature sensor reading wrong — A sensor that has drifted rather than failed tells the control the cabinet is already cold, so the unit stops cooling while insisting nothing is wrong.
What to check first, second, third
- Look at the freezer rear panel for frost — Frost hiding the vents confirms the air path is blocked and tells you the defrost side is where to look.
- Close the door on a strip of paper and pull it out — If it slides out without drag the gasket is not sealing at that point, and you have found a cause before opening anything.
- Read the temperature with a thermometer in a glass of water, not from the display — A display reports what the control believes.
Step by step, as far as it is safe to go
- Verify with a thermometer rather than the display — A refrigerator holds food safely at 40 °F (4 °C), and a freezer at 0 °F (−18 °C) — check against those, not against a number on a panel.
Tools: thermometer
- Move the unit out and give it its stated clearance — Then leave it closed for a day before judging whether anything changed.
- STOP at the point where a panel or a meter is needed — Testing a fan motor, a defrost heater or a sensor means live terminals behind a panel.
Before you open anything
Safety
Move a full-size cabinet with help rather than alone: they are top-heavy on wheels and they catch on flooring. Unplug before touching anything behind a panel, and remember stored charge remains after the supply is cut.
Where the owner side ends
If the coil is clean, the doors seal, the vents are clear and a day has passed with no improvement, the next tests are behind a panel with a meter. Call sooner if the freezer has thawed, because food safety sets the clock rather than the fault does.

Scope of this page
This page is generalized across Chill by Hisense refrigerator families and model lines. Wiring colours, torque figures and board part numbers are deliberately not here — they differ by family. A family- or model-specific page, where one exists, is linked below and is the more specific answer.
