How long do refrigerator compressors last?
The lifespan of a refrigerator compressor can vary depending on several factors, including usage, maintenance, and quality of the unit. On average, a household refrigerator with a typical working capacity of 500-600 gallons can expect to last around 10 to 15 years.
What are the signs that indicate a faulty compressor?
A faulty compressor typically displays one or more of the following signs, indicating that the compressor may need to be replaced, maintained, or serviced:
Unusual noises: clicking, whining, grinding, or squealing sounds from the compressor, which can be caused by worn seals, low oil levels, or faulty belts, often accompanied by a low or increasing idle speed.
Reduced compressor hour rating: the compressor’s power consumption and operational life may be significantly reduced compared to its typical or manufacturer’s guidelines, indicating the compressor’s degrading condition and potentially pointing to underlying problems such as excessive oil leaks, compressor drum or bushing damage, or refrigerant restriction.
Sudden and unexplained voltage drops: compressor owners often notice changes in their electrical system, such as voltage drops or decreased AC power, which can be a sign of a power supply issues, a faulty capacitor, or over-voltage conditions during startup.
Difficulty starting or revving: when trying to start or run the compressor, you might feel that it doesn’t take off power or vibrates weakly, or the startup noise may be overly loud, which might be some indication that the compressor’s engine is failing or weak.
Increased suction or discharge pressures: the compressor’s compressor-driven pressure controllers usually indicate exactly the pressure (and sometimes flow rate) they are receiving from the engine. An engine failure could mean the compressor failure, in many cases. Typically, these pressure regulators adjust themselves in response to a specific signal from the compressor.
Frequent oil leaks: Worn seals or low oil levels in the compressor are commonly due to compressor compressing unevenly and that low seals near high velocities causing high piston and crankcase worn at bottom piston seals – losing low pressure oil capacity. For example, some leakage that won’t stem through added leaks may suggest just full low compression.
Frequent maintenance or repair issues: Avoidable repairs or repeated maintenance efforts can be signs of compressor failure, requiring replacement.
Failure to maintain proper storage conditions: Failure to store the refrigerant and the charging / metering equipment properly can lead to compressor degradation and reduced efficiency.
Other signs: other common examples may include decreased cooling water flow rates, high CO2 values (compared to normal readings), unusual temperature readings, or any failure to turn on when manually powered by the thermostat.
Can a faulty compressor be repaired, or does it need to be replaced?
A faulty compressor can be fixed, but it often depends on the specific issue and the quality of the part used. If the compressor is an older model or has a simple design, it might be possible to repair it by replacing the faulty component with a compatible equivalent. However, if the compressor has advanced technology features such as multiple compression stages, advanced vapor compression, or high-pressure oil circuits, it may not be feasible or safe to perform repairs. In such cases, replacing the compressed air system entirely with a new unit from a reputable manufacturer can be the most cost-effective and efficient option. Nevertheless, before making any decisions, it is recommended to consult with a professional HVAC or compressor repair technician to assess the situation and provide guidance on the best course of action.
How often should refrigerator compressors be serviced?
Refrigerator compressors typically require annual maintenance to ensure optimal performance and longevity. Assuming you refer to the serial number on the compressor or the manufacturer’s specifications, here’s a detailed periodical service schedule:
Standard Re-inspection: Every 3 years (6,000 to 7,000 hours) from the original installation date or when the compressor’s performance begins to degrade.
Seasonal Checks: Perform a thorough inspection every 6 months (at least 1,000 hours) to:
– Check for air leaks, moisture accumulation, and dirty seals.
– Monitor the compressor’s oil levels and inspect the oil drip pan.
– Verify the thermostat’s operation and test the temperature setting.
Additional Frequencies:
– Severe Weather Events: Handle cold snaps or extreme temperatures (below -20°C/-4°F) with thorough cleaning and maintenance (every 2 years, or 3,000 to 4,000 hours).
– High-Temperature Operations: Overload the compressor during periods of high usage to allow the components to absorb any excess energy; perform regular checks and maintenance (optional).
Service Recommendations: Consulting your compressor’s owner’s manual, many manufacturers will recommend specific maintenance procedures and schedules.
Note: Early detection and prevention of potential issues can make the process of maintenance more economical and efficient. If you’re unsure about your compressor’s maintenance requirements or have a non-standard inspection schedule, consider consult a trusted appliance repair expert or the manufacturer’s authorized repair service provider.
