GE Refrigerator Inverter Compressor: Loud Vibrating... | appliancefaults.com

Technical Background:

The inverter compressor is controlled by the main control unit (MCU) and the inverter board. The MCU sends signals to the inverter board, which then modulates the voltage and frequency supplied to the compressor. Voltage paths are crucial for proper operation and can affect compressor performance and noise levels.

Symptoms:

The homeowner observes a loud vibrating noise emanating from the rear of the GE refrigerator, specifically near the compressor. The noise may be constant or intermittent and is perceived as abnormal.

Possible Causes:

Loose mounting hardware on the compressor.
Compressor internal failure (worn bearings or pistons).
Excessive refrigerant charge causing back pressure.
Faulty compressor start relay or inverter board.
Foreign object lodged near the compressor (tubing).
Unstable refrigerator placement, amplifying vibrations.

Solution:

1

Unplug the refrigerator and locate the compressor at the rear of the unit.
2

Inspect the compressor mounting bolts. Tighten any loose bolts using a 1/2-inch wrench.
3

Check the refrigerant lines for contact with other components. Carefully bend lines away if necessary.
4

Using a multimeter, check the voltage to the compressor from the inverter board. It should be around 120V AC when the compressor is running.
5

If voltage is present, use an amp clamp to measure the compressor's running amperage. Compare this to the nameplate value on the compressor.
6

If amperage is excessively high or low, the compressor is likely failing. Replace the compressor.
7

If the compressor appears mechanically sound, suspect a faulty inverter board. Replace the inverter board.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before performing any repairs. Inverter boards and compressors can hold high voltage even after being unplugged. Observe proper Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Regularly clean the condenser coils (at least every 6 months) using a vacuum cleaner with a brush attachment. Ensure the refrigerator is level and stable on the floor. Avoid overloading the refrigerator, as this can cause the compressor to work harder and potentially fail.

Expert Tip:

Many GE refrigerators have a service mode that can be accessed by pressing specific button combinations. Refer to the service manual for your specific model to access diagnostic information, including compressor RPM and fault codes. This can help pinpoint the source of the noise.

Frequently Asked Questions

•What is the typical lifespan of a GE refrigerator inverter compressor?

A properly maintained GE refrigerator inverter compressor should last between 10-15 years. Factors such as ambient temperature, usage patterns, and maintenance practices can affect its lifespan.

•How can I determine if the inverter board is faulty without specialized equipment?

While specialized equipment is ideal, you can visually inspect the inverter board for signs of damage such as burnt components, bulging capacitors, or corrosion. A faulty inverter board may also exhibit erratic compressor behavior or complete failure to start.

•What type of refrigerant is typically used in GE inverter refrigerators, and what are the regulations regarding its handling?

GE inverter refrigerators typically use R-134a or R-600a refrigerant. R-134a is being phased out due to environmental concerns. R-600a is flammable and requires special handling procedures. EPA Section 608 certification is required for refrigerant handling and disposal.
