Hotpoint Refrigerator Not Cooling, But Freezer Is... | appliancefaults.com

Technical Background:

The refrigerator's Main Control Unit (MCU) manages the cooling cycle, monitoring temperatures via thermistors and controlling the compressor, fans, and defrost system. Voltage paths within the MCU activate relays that power these components. A failure along any of these voltage paths or a faulty thermistor reading can lead to improper cooling.

Symptoms:

The US homeowner observes that the freezer section of their Hotpoint refrigerator is freezing normally, but the refrigerator section is not cooling adequately or at all.

Possible Causes:

Faulty damper control
Defrost system failure (heater, thermostat, timer, or control board)
Blocked air vents between freezer and refrigerator
Evaporator fan motor malfunction
Refrigerant leak (less likely but possible)

Solution:

1

Check the damper control: Locate the damper (usually at the top of the refrigerator section). Ensure it opens and closes freely. If it's stuck closed, replace it.
2

Inspect the evaporator fan: Open the freezer and check if the fan is running. If not, test the fan motor for continuity with a multimeter. If no continuity, replace the fan motor.
3

Examine the defrost system: Check the defrost heater for continuity with a multimeter. If no continuity, replace the heater. If the heater is good, check the defrost thermostat (bi-metal) for continuity when cold. If no continuity, replace the thermostat. You may also need to investigate the defrost timer or control board using a multimeter and wiring diagram.
4

Check for blocked vents: Make sure no items are blocking the air vents that circulate cold air from the freezer to the refrigerator. Clear any obstructions.
5

Check door seals: Ensure the refrigerator and freezer door seals are intact and sealing properly. Replace if damaged.
6

If equipped with an electronic control board, inspect for any burnt components or failed relays. Replace if necessary.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before performing any repairs (LOTO - Lock Out/Tag Out). Be aware of high voltage components within the refrigerator's control system.

Prevention:

Clean the condenser coils every 6 months with a vacuum cleaner and brush attachment. Ensure proper air circulation around the refrigerator. Avoid overpacking the refrigerator section.

Expert Tip:

Many Hotpoint refrigerators have a service mode. Consult the service manual for the specific model. A common sequence is pressing and holding the freezer and refrigerator temperature adjustment buttons simultaneously for 5 seconds. This may allow you to manually activate components for testing.

Frequently Asked Questions

•How do I manually defrost the refrigerator?

Unplug the refrigerator for 24 hours, leaving both doors open. Place towels to absorb any water. Reconnect power after 24 hours.

•Where is the defrost timer located on my Hotpoint refrigerator?

The defrost timer's location varies by model. It's often behind the kickplate at the bottom front, or behind the control panel inside the refrigerator section. Consult the service manual for the exact location.

•What should the temperature be in the refrigerator section?

The ideal temperature range for the refrigerator section is between 35°F and 40°F.
