- ►PARTS DESCRIPTION: Refrigerator Compressor
- ►GENUINE: From Genuine OEM Replacement Parts
- ►OEM PART #: 5304532179, 5304533694
- ►MANUFACTURER PART #: VTH1111Y, 230V 40-150Hz R600a
- ►NOTICE: Replacing a compressor requires professional skills and specialized equipment
- This controller automatically adapts to dual-voltage DC power input systems of 12V and 24V. For 12V DC systems, the maximum input voltage is 17V; for 24V systems, the maximum input voltage is 31.5V.
- The controller operates within an ambient temperature range not exceeding 50°C. If the controller housing temperature becomes excessively high, the compressor will stop to activate over-temperature protection (Recommendation: When ambient temperatures are high, implement forced air cooling for the controller).
- The controller's power input wires connect directly to the battery's positive and negative terminals. The controller's (-) terminal connects to the battery's negative terminal; the controller's (+) terminal connects to the battery's positive terminal. Failure to do so will prevent the controller from functioning properly. The controller features reverse polarity protection.
- The temperature switch is connected to the C and T terminals of the controller. If no resistor is connected between them, the compressor operates at 2000 rpm when the temperature switch closes.
- External Fan: A 12V DC fan can be connected between the controller's (F+) and (F-) terminals. The fan's positive terminal connects to the controller's (F+) terminal, and the negative terminal connects to the controller's (F-) terminal. When the controller's input voltage exceeds 12V, the output voltage between terminals (F+) and (F-) always remains at 12V. Regardless of whether the input voltage system is 12V or 24V, the fan must be a 12V DC fan.

Choosing the Right Heartbeat for Your Fridge: A Compressor Buying Guide
The compressor is the engine of your refrigerator. It pumps the cold stuff around to keep your food fresh. Buying a new one can seem tricky, but this guide makes it easy.
1. Key Features to Look For
When you shop, look closely at these important parts.
- **Cooling Capacity (BTUs/hr):** This tells you how much heat the compressor can move. Bigger fridges need higher capacity. Think about the size of your freezer and fridge sections.
- **Voltage and Frequency:** Make sure the compressor matches your home’s electricity. Most standard fridges use 115V/60Hz in the US. Check the label on your old unit!
- **Type of Refrigerant:** Modern fridges often use R600a (isobutane) or R134a. Ensure the new compressor works safely with the refrigerant your fridge uses. R600a is becoming more common because it’s better for the environment.
- **Motor Type:** Look for Energy Efficient (EE) ratings. Inverter compressors run at variable speeds, saving energy compared to older, fixed-speed types.
2. Important Materials
The parts inside the compressor need to last a long time.
Most modern compressors use strong metal casings, usually steel or aluminum alloy. These materials resist rust and handle the high pressure inside. The internal windings often use copper wire because copper moves electricity very well. Good quality seals prevent the cold gas from leaking out. Always check reviews to see if users report early seal failures.
3. Factors That Improve or Reduce Quality
Quality affects how long your fridge stays cold and how much noise it makes.
What Makes Quality Better?
- **Brand Reputation:** Established brands often use better testing procedures. This means fewer surprises down the road.
- **Warranty Length:** A longer warranty shows the manufacturer trusts their product. A two-year warranty is usually better than a 90-day one.
- **Low Noise Rating:** High-quality compressors are designed to run quietly. If the decibel (dB) rating is low, your kitchen stays peaceful.
What Lowers Quality?
Cheap, off-brand replacements might save you money now. However, these units sometimes use thinner metal casings or lower-grade internal components. This often leads to the compressor breaking sooner or running very loudly. Using the wrong refrigerant type will quickly ruin a new compressor.
4. User Experience and Use Cases
How the compressor works affects your daily life.
Noise Level
If you have an open-plan living space, noise matters a lot. Inverter compressors generally provide a much smoother, quieter experience. You often hear them humming softly instead of clicking on loudly.
Energy Use
A highly efficient compressor lowers your electric bill. While the upfront cost might be higher, the energy savings add up yearly. This is especially true if your old fridge ran constantly because the compressor was failing.
Common Use Cases
- **Direct Replacement:** If your old compressor failed, you need an exact match for size and electrical specs to ensure easy installation.
- **Upgrading Efficiency:** If your fridge is old, swapping the compressor for a modern, high-efficiency model can sometimes extend the life of the whole appliance, provided the old evaporator coils are clean.
10 Frequently Asked Questions (FAQ) About Refrigerator Compressors
Q: How do I know if my refrigerator compressor is failing?
A: You will hear loud clicking, buzzing, or the fridge might not cool at all. Sometimes the compressor runs constantly but never gets cold.
Q: Can I replace my refrigerator compressor myself?
A: No, this job is best left to certified technicians. Refrigerant handling requires special tools and licenses because the gases can be harmful.
Q: What is the difference between an AC and a DC compressor?
A: AC compressors use standard wall power directly. DC compressors are often used in RV or marine refrigerators and need a power converter.
Q: Does the size of the compressor matter more than the brand?
A: Both matter greatly. The size (capacity) must match the fridge, but the brand quality determines how long that capacity lasts.
Q: How long should a new refrigerator compressor last?
A: A good quality compressor, properly installed, should last 10 to 15 years, often matching the life of the refrigerator itself.
Q: What happens if I use the wrong type of oil in the compressor?
A: Using the wrong oil causes friction and heat inside the pump. This friction quickly destroys the moving parts, leading to an early breakdown.
Q: Is a new, energy-efficient compressor always more expensive?
A: Yes, the initial purchase price is usually higher, but they save money over time through lower electricity use.
Q: What is the “start relay” and is it part of the compressor?
A: The start relay is a small electrical part attached to the outside of the compressor. It gives the motor the initial jolt it needs to start running, but it is a separate component you might need to replace too.
Q: Will a noisy compressor always need replacement?
A: Loud noises usually mean internal wear or a bad fan motor, but a severely loud, metallic grinding noise often signals that the compressor itself needs replacement.
Q: What is the lifespan difference between R134a and R600a compressors?
A: The refrigerant type does not directly affect lifespan; the quality of the manufacturing and installation determines longevity.
