GE Refrigerator Inverter Compressor: Clicking Sound... | appliancefaults.com

Technical Background:

GE inverter refrigerators utilize a variable-speed compressor controlled by an inverter board (MCU). The MCU regulates the compressor's speed based on cooling demand. The inverter board converts AC voltage to DC voltage to power the compressor. Voltage is delivered to the compressor, but is interrupted via the overload protection which causes the click.

Symptoms:

The homeowner reports a distinct clicking sound emanating from the back of the refrigerator, specifically near the compressor, occurring approximately every 5 minutes. The refrigerator may or may not be cooling effectively.

Possible Causes:

Compressor relay failing to engage.
Compressor starting capacitor issue.
Overload protector tripping due to high current draw.
Inverter board malfunction.
Locked rotor in the compressor motor.
Low refrigerant charge causing compressor overheating.

Solution:

1

Unplug the refrigerator from the 120V AC outlet.
2

Access the compressor compartment at the rear of the refrigerator.
3

Visually inspect the compressor relay and overload protector for burn marks or damage.
4

Use a multimeter to test the compressor windings for continuity. Resistance should be present, but not open or shorted to ground.
5

Check the voltage to the compressor from the inverter board. You should see varying DC voltage (typically 50-150V DC) when the compressor is supposed to be running.
6

If voltage is present but the compressor is not starting, replace the compressor relay or the entire inverter board.
7

If the compressor is still clicking, the compressor itself may be faulty and require replacement by a qualified technician.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before performing any repairs. Inverter boards can store high voltage even after being disconnected from the power source. Use caution when working around electrical components.

Prevention:

Clean the condenser coils at least twice a year using a vacuum cleaner with a brush attachment. Ensure proper ventilation around the refrigerator. Avoid overloading the refrigerator with warm food, which can cause the compressor to work harder and overheat.

Expert Tip:

GE refrigerators often have a diagnostic mode accessible through the control panel. Consult the service manual for the specific model to access the diagnostic mode and check for error codes. This can help pinpoint the source of the problem. The typical sequence involves pressing certain buttons in quick succession (e.g., ENERGY SAVER, then FREEZER UP, ENERGY SAVER, FREEZER UP). This will display error codes.

Frequently Asked Questions

•What is the proper resistance reading for the compressor windings?

The specific resistance varies by model, but typically each winding should have a resistance of between 2 and 15 ohms. Consult the service manual for your specific model.

•How do I safely discharge the capacitor on the inverter board?

The safest method is to use a high-wattage resistor (around 10k ohms) to slowly drain the capacitor. Connect the resistor leads to the capacitor terminals for several minutes before handling the board.

•Where can I find a replacement inverter board for my GE refrigerator model?

Replacement inverter boards can be found at appliance parts retailers such as AppliancePartsPros.com, RepairClinic.com, or through GE's official parts website. Be sure to have your refrigerator's model number handy.
