Fridge Thermostat Replacement in Warsaw
25.03.2026Fridge Thermostat Replacement in Warsaw
Fridge freezing everything, not cooling enough, or compressor running non-stop? The thermostat controls compressor cycling to maintain set temperature. When it fails, the fridge either over-freezes or under-cools. We replace thermostats on site across Warsaw — from Ursus to Targówek.

- Good lighting.
Case from Warsaw
Client in Ursus: Samsung No Frost — fridge compartment at +12°C instead of +4°C. Compressor cycling on for a minute then off. Electronic sensor was reading wrong temperature — board thought it was cold. Replaced sensor. After 2 hours, stable +4°C. 40 minutes. Tip: if fridge is warm, check actual temperature with a thermometer — often it’s the sensor, not the compressor.
