Cooling systems are the heart of a business, especially in the food, healthcare, and logistics sectors. The smooth operation of these systems largely depends on spare parts management. As a technical service specialist with many years of experience in the field, I can say this clearly:Failure to replace a small part in time leads to significant costs.
This guide will detail the most frequently failed parts, replacement times, failure symptoms, and professional tips.
🔧 The Importance of Spare Parts Management in Cooling Systems
Cooling systems are systems that operate continuously and are under heavy load. Therefore:
Proper maintenance + timely parts replacement = lower cost + longer lifespan.
🔝 Top 10 Most Frequently Replaced Cooling Replacement Parts
Average Lifespan:3-5 years Price: 500 – 1.800 TL
The thermostat is the brain of the system. It senses the temperature and controls the compressor.
In a supermarket, a freezer that should have been at -18°C was operating at -10°C. After replacing the thermostat, the system was corrected within an hour.
💡 Pro Tip: Digital thermostats are more accurate and have a longer lifespan.
2. Contactor (Compressor Switch)
Lifespan:5-7 years Price: 200 – 600 TL
It transmits the electrical current to the compressor.
3. Defrost Timer
Lifespan:4–6 years Price: 350 – 900 TL
It defrosts automatically.
4. Door Seal
Lifespan:2-4 years Price:150 – 450 TL/meter
It provides a leak-proof seal.
Paper test → if it comes off easily, the gasket is worn out.

6. Compressor (The Heart of the System)
Lifespan:8–15 years Price: 5.000 – 25.000 TL
It's the most critical part.
⚠️ Important:When choosing a compressor, never opt for a cheap aftermarket alternative.
7. Expansion Valve
Lifespan:5-10 years Price: 1.000 – 3.500 TL
It controls the flow of the coolant.
8. Pressure Switch (Pressurestat)
Lifespan:5–8 years Price: 400 – 1.200 TL
It is for system protection purposes.
9. Electronic Card
Lifespan:5-10 years Price: 1.500 – 6.000 TL
