ToggleUnderstanding Your Fridge’s Compressor
What is a Fridge Compressor and How Does it Work?
The compressor is essentially the heart of your refrigerator. It circulates refrigerant through the coils, converting it from gas to liquid and back, to keep the refrigerator cool. Think of it as the engine that powers your cooling system.[1]
Signs of Compressor Issues
- Fridge Not Cooling: If your fridge isn’t maintaining its temperature, the compressor might be failing.
- Strange Noises: Unusual clicks, hums, or rattles can indicate compressor problems.
- Overheating: If the compressor feels excessively hot, it’s struggling and may need attention.[2]
Pre-Check Preparation
Safety First
Before you start tinkering, let’s talk safety. Always disconnect the power supply to avoid any accidents. Make sure you have the right tools on hand: a multimeter, gloves, and perhaps some safety goggles for good measure.
Tools and Protective Gear Needed
- Multimeter: For testing electrical resistance and continuity.
- Insulated Gloves: To protect against electric shock.
- Safety Goggles: To keep your eyes safe from any potential hazards.[3]
Accessing the Compressor
Most compressors are located at the back or bottom of the fridge. Remove the access panel carefully, ensuring not to damage any components.
How to Check Fridge Compressor Visualy?
Perform a Visual Check
Look for obvious signs of wear and tear:
- Leaks: Any refrigerant leaks?
- Corrosion: Rust or corrosion on the compressor or nearby parts.
- Damaged Wires: Frayed or burnt wires can indicate electrical issues.
Check the Start Relay and Overload Protector
These components help the compressor start and run smoothly. If they’re damaged, replace them immediately.
When to Call a Professional
If you see visible damage or signs of electrical issues, it’s best to call in the experts. Unity Cooling Systems Inc. is always here to help.
Testing the Compressor
Using a Multimeter
A multimeter is your best friend for this task. Here’s how to use it:
- Set the Multimeter: Turn it to the ohms (Ω) setting.
- Identify the Terminals: You’ll see common (C), start (S), and run (R) terminals on the compressor.
- Measure Resistance: Check the resistance between C-S, C-R, and S-R. Healthy readings usually fall within a specific range outlined in your fridge’s manual.
Interpreting Results
- Healthy Compressor: Consistent resistance readings across the terminals.
- Signs of Failure: High or infinite resistance indicates a problem.
Troubleshooting Tips
- Low Resistance: May indicate a short in the windings.
- High Resistance: Could mean an open winding or a broken connection.

How Knowing How to Check Your Fridge Compressor Can Save You Thousands
Ever wondered if your fridge or freezer is running efficiently? Let’s dive into a real-life example to show why knowing how to check your fridge compressor matters and the potential savings for businesses around here.
Example: Samantha’s Culinary Haven
Samantha runs a bustling spot, Samantha’s Culinary Haven, right here in Houston. Her restaurant relies on top-notch commercial refrigeration to keep things fresh. One day, she noticed her fridge wasn’t cooling properly and there was a strange noise coming from it.
Initial Problem: Samantha’s refrigerator compressor was malfunctioning.
Impact on Business:
- Lost Revenue: Due to spoilage, Samantha lost about $500 worth of perishable goods.
- Emergency Service Call: The urgent repair service cost her $350.
- Business Interruption: The kitchen was down for a day, resulting in an estimated $2,000 in lost sales.
Total Initial Loss: $2,850
By learning how to check her refrigerator compressor, Samantha could have spotted the issue earlier, avoiding the emergency costs and business disruption.
The Math Behind the Savings
Let’s break down the potential savings:
- Routine Check-up: Performing regular checks on her refrigerator compressor could prevent unexpected breakdowns. Suppose a professional check-up costs $100 every six months.
- Preventive Maintenance: This would help identify issues like failing condenser coils or an overheating compressor before they become serious.
Annual Check-up Cost: $200
Potential Savings:
- Spoilage Prevention: Avoiding spoilage worth $500 twice a year = $1,000
- Emergency Service Savings: Avoiding one emergency repair = $350
- Sales Loss Prevention: Preventing business interruption once a year = $2,000
Total Potential Savings: $3,350 – $200 (check-up cost) = $3,150 per year
