Quick answer: If your Hisense fridge is warm but the freezer is still cold, the most common cause is a failed evaporator fan motor — the fan that circulates cold air from the freezer compartment into the fridge. Fan motor K1629352 is $69.95 and is a straightforward DIY replacement. A new fridge costs $800–$2,000, so the fan is almost always worth fixing first.

How does a Hisense frost-free fridge actually cool?
Most Hisense refrigerators sold in Australia use a frost-free system with a single sealed refrigeration circuit. The compressor and condenser are located at the rear or underneath the cabinet. Cold refrigerant passes through the evaporator coil, which lives behind a panel inside the freezer compartment.
The key component that most people don’t realise exists is the evaporator fan motor. This small electric motor drives a fan that draws air over the evaporator coil and pushes it through internal ducts into both the freezer and the fridge section. Without that fan running, the freezer stays cold — because the evaporator is right there — but the fridge section warms up rapidly. This is the single most common symptom pattern on Hisense models: cold freezer, warm fridge.
The fan motor runs on a duty cycle controlled by the main PCB or a simple timer. Because it runs almost continuously, the bearings wear over time. When the bearings seize or the motor windings fail, the fan stops, airflow to the fridge section drops to zero, and temperatures climb above safe food storage levels within a few hours.
Why is the fan motor the number one cause on Hisense fridges?
Hisense has sold a very high volume of refrigerators in Australia through major retail chains since the mid-2010s. The fan motor is a wear item: bearing life is typically five to ten years depending on duty cycle and ambient temperature. In warm Australian climates — particularly in kitchens without air conditioning or in garages — motor bearings wear faster.
A failing motor sometimes gives a warning sign before it stops completely: you may hear a humming, buzzing, or grinding noise coming from the freezer compartment for days or weeks before the fridge section warms up. Many owners mistake this for normal compressor noise and ignore it until the fridge is already warm.
The good news is that replacing the fan motor is a genuine DIY repair. It requires removing a few internal panels, unplugging a wiring connector, unscrewing the motor bracket, and fitting the new unit. No refrigerant is involved. The whole job takes around 30 minutes for someone reasonably comfortable with a screwdriver.
What causes a Hisense fridge not to cool?
| Cause | Likelihood | Symptoms | Fix |
|---|---|---|---|
| Evaporator fan motor failed | Very likely | Fridge warm, freezer cold, no airflow from fridge vents, possible buzzing noise before failure | Replace fan motor — DIY, 30 minutes |
| Defrost failure causing ice blockage | Likely | Fridge gradually warms over days, freezer may also be marginal, ice wall behind freezer panel | Manual defrost first, then replace defrost heater or sensor |
| Thermostat fault | Possible | Fridge runs warmer than set temperature, compressor may cycle too short | Replace thermostat |
| Door seal worn or damaged | Possible | Fridge struggles to reach temperature, frost forms near door edges, higher power bill | Replace door gasket |
| Compressor or PCB fault | Rare (in fridges under 10 years) | Both fridge and freezer warm, compressor silent or clicking, no cooling at all | Call a licensed refrigeration technician |
How to diagnose a Hisense fridge that is not cooling
- Check the freezer first. Open the freezer and confirm it is cold. If the freezer is also warm, the problem is likely the compressor or refrigerant circuit — skip ahead to the “when to call a technician” section. If the freezer is cold but the fridge is warm, proceed to step 2.
- Listen for the evaporator fan. Open the fridge door and hold it open (tape down the door switch if needed to keep the light off). Listen for a faint fan noise coming from the back wall of the freezer or the vents between the two compartments. No fan noise strongly suggests fan motor failure.
- Check for airflow at the fridge vents. Place your hand near the cold air vents inside the fridge section (usually on the rear wall or top). If you feel no airflow while the compressor is running, the fan is not working.
- Check for ice blockage behind the freezer panel. If you can feel very limited airflow (rather than none), a build-up of ice on the evaporator coil may be restricting it. Remove the back panel inside the freezer (usually held by two or three screws). If the evaporator coil is encased in a thick layer of ice, the defrost system has failed.
- Inspect door seals. Close the fridge door on a piece of paper. If the paper slides out easily, the seal is not gripping properly and warm air is entering. Repeat on all four sides of both doors.
- Find the model number. Open the fridge door and look for the model sticker on the interior side wall or door frame. Note the full model number before ordering any parts — Hisense has sold many similar-looking models with different motor fitments.
How to replace the evaporator fan motor on a Hisense fridge
- Unplug the fridge at the wall. Never work on a live appliance.
- Empty the freezer and remove the shelves and any ice trays or drawers.
- Remove the freezer back panel. This is usually a plastic panel held by two to four screws (Phillips head). Set the screws aside in a safe place.
- Locate the fan motor assembly. It will be mounted on a bracket behind or adjacent to the evaporator coil. You will see a small plastic fan blade attached to a motor.
- Disconnect the wiring connector. The motor connects via a small two- or three-pin connector. Squeeze the clip and pull straight — do not tug on the wires.
- Remove the motor bracket screws (usually two or three screws) and lift the motor free.
- Pull the fan blade off the motor shaft. It is usually a push-fit. Retain the blade for fitting to the new motor.
- Fit the replacement motor, push the blade back onto the shaft, reconnect the wiring connector, and refit the bracket.
- Refit the freezer back panel and all shelves.
- Plug the fridge back in and monitor over the next two hours. The fridge section should return to temperature within 90–120 minutes.

When to call a technician instead of DIYing
If both the fridge and freezer compartments are warm and the compressor is silent or emitting a clicking sound (the compressor trying and failing to start), the refrigeration circuit itself has failed. This could be a compressor fault, a PCB fault controlling the compressor relay, or a refrigerant leak. Compressor replacement and refrigerant work require a licensed refrigeration technician and are generally not cost-effective on fridges over eight years old. Get a quote and weigh it against the cost of a replacement unit.
If you have replaced the fan motor and the fridge still does not cool properly, the next diagnostic step is the defrost heater and defrost sensor, which require a multimeter to test. A local appliance repairer can confirm this in a single service call.
Frequently asked questions
My Hisense fridge freezer is cold but the fridge section is warm — is this definitely the fan motor?
It is the most common cause, but not the only one. Start by listening for fan noise and checking for airflow at the fridge vents. If there is no airflow and you can hear the compressor running, the fan motor is the most likely culprit. An ice blockage on the evaporator (defrost failure) produces the same symptom but usually develops gradually over several days rather than suddenly.
How do I find the right fan motor for my Hisense model?
Check the model sticker inside the fridge door frame or on the interior side wall. Enter that model number into our Part Finder or search for Hisense fridge parts and match your model to the listing. Fan motor fitment is model-specific — always verify before ordering.
Can I manually defrost my Hisense fridge to fix a no-cooling problem?
Yes, if an ice blockage on the evaporator is the cause. Unplug the fridge, leave both doors open, and allow 24–48 hours for all ice to melt. Place towels on the floor to catch water. If the fridge cools normally after this but then warms up again over the following weeks, the defrost heater or sensor has failed and needs replacing.
How long should a Hisense fridge last in Australia?
Most Hisense fridges sold in Australia have a practical service life of eight to twelve years with normal maintenance. Evaporator fan motors are typically the first wear item to fail, usually after five to eight years. Replacing the fan motor for under $70 can extend the fridge’s life by several more years.
Is it safe to eat food from a fridge that has been warm overnight?
The general food safety guideline is that perishable food left above 5 °C for more than four hours should be discarded. If the fridge has been warm for a full day or more, err on the side of caution with meat, dairy, and cooked leftovers. Non-perishables and sealed condiments are generally safe.
