Is it really the compressor?
Many refrigerators are declared "dead compressor" when the real failure is something cheaper. Before we quote a compressor, we rule out:
- A dirty condenser or failed condenser fan. High head pressure makes a healthy compressor overheat and trip. This is very common in Las Vegas heat.
- A failed start relay or overload. A refrigerator that clicks every few minutes often needs a part costing far less than a compressor. See refrigerator clicking.
- A failed inverter board. Variable-speed compressors on LG, Samsung, Whirlpool and many built-ins are driven by an electronic board that can fail on its own.
- A refrigerant leak. A low charge makes the compressor run nonstop without cooling. The compressor is fine; the leak is the problem. See refrigerant leak repair.
We confirm a compressor failure with winding resistance tests, amperage draw, start-component tests and system pressures or temperatures. You get the reading, not just a verdict.
What a proper compressor replacement includes
- Recovery of the existing refrigerant into certified recovery equipment. Venting refrigerant is illegal under EPA rules.
- Removal of the failed compressor.
- Installation of the correct compressor for your model's refrigerant type and capacity (R-134a, R-600a isobutane and others).
- A new filter-drier, replaced every time the system is opened.
- Brazing with nitrogen purge to prevent internal scale.
- Pressure and leak testing.
- A deep vacuum to remove moisture and non-condensables.
- A weighed refrigerant charge to the exact amount on the model label. Household refrigerators carry a few ounces, so guessing is not acceptable.
- A performance test over a full cooling cycle before we leave.
Luxury and built-in compressors
Sub-Zero, Viking, Thermador, Monogram and other built-ins mount the compressor on top of the cabinet. Many use variable-speed compressors with their own electronic control. These replacements take more time and use brand-specific parts, but they are almost always worth it: replacing a built-in costs many thousands of dollars plus cabinet work. See built-in refrigerator repair.
Typical cost
| Refrigerator | Typical total (parts + labor) |
|---|---|
| Standard freestanding | $900 – $1,600 |
| Built-in / luxury | $1,400 – $3,000 |
Prices depend on the compressor, refrigerant type and access. You get a written price before any work begins, and the service call is $75.
Warranty
Labor is guaranteed for 90 days. The compressor carries its manufacturer's warranty, usually one year. Some manufacturers, notably LG, have offered extended warranties on certain compressors. If yours is covered, the part may be free and you pay only for labor.
Frequently asked questions
Is it worth replacing a refrigerator compressor?
On built-in and luxury refrigerators, almost always. On a freestanding refrigerator under about eight years old, usually. On a freestanding unit over ten years old, compare the quote with the cost of a new refrigerator — we will give you both numbers honestly.
How long does a compressor replacement take?
Usually three to five hours in your home once the part is on hand. Built-in models can take longer. Common compressors are often available within one to three business days.
Can any appliance technician replace a compressor?
Federal law requires EPA Section 608 certification to open a refrigeration system and handle refrigerant. Every one of our technicians is certified.
Do you offer a second opinion if another company said my compressor is bad?
Yes. A second opinion costs $75, and it is the cheapest way to avoid paying for a compressor you do not need.
