Fridge Thermostat Replacement in Warsaw
Is your fridge freezing all the food, not cooling properly, or is the compressor working without a break? The thermostat manages compressor on/off cycles to keep the set temperature. When it stops working, the fridge may either freeze too much or cool too little. We replace thermostats on site all over Warsaw — from Ursus to Targówek.

How it works
- You explain the problem — freezing, warm interior, compressor running all the time.
- The technician brings the thermostat.
- Disconnect power.
- Find the thermostat — behind the dial or on the back wall.
- Check it with a multimeter.
- Install the new one, route the capillary tube or connect the sensor.
- Switch power back on, wait 15–20 min, and confirm the compressor cycles as it should.
Mistakes
- Mixing it up with a refrigerant leak — both can make the fridge warm.
- Setting the dial to max — that won’t fix a faulty thermostat.
- Using the wrong thermostat range.
- Missing the fact that the compressor runs 24/7 — electricity costs go up fast.
- Bypassing thermostat contacts — the compressor keeps running and the food freezes.
Preparation
- Fridge model.
- Description of the issue.
- Move the food into a cooler.
- Unplug the fridge.
- Access to the rear.
- Photo of the model label.
- Clear the top of the fridge.
- Good light.
Case from Warsaw
Client in Ursus: Samsung No Frost — fridge compartment was at +12°C instead of +4°C. The compressor was switching on for a minute and then off again. The electronic sensor was reading the wrong temperature — the board thought the compartment was already cold. We replaced the sensor. After 2 hours, it held a steady +4°C. 40 minutes. Tip: if the fridge feels warm, measure the real temperature with a thermometer — very often the problem is the sensor, not the compressor.
