【Why Your Fridge Isn’t Working After Replacing the Thermostat】Check the Basics First: 1. Is the fridge plugged in? Try a different outlet. 2. Listen for a humming sound – if you hear it, the compressor might be stuck (common fix: tap it gently).
Thermostat Installation Blunders 1. Wrong wiring? Match the colors (red=power, yellow=compressor, etc.). 2. For digital thermostats: Did you reset it? Hold the "Reset" button for 5 secs.
Compatibility Issues 1. Is the new thermostat made for your fridge model? (Sam sung/L G often need specific ones). 2. Mechanical vs. digital? Don’t mix them – check your manual.
Quick Fixes: 1.Unplug for 10 mins → Plug back in (resets the system). 2.Test the thermostat: Turn it to coldest setting → You should hear a click within 5 mins
Still stuck? 1. Safety first! Turn off power before checking wires. 2. Call a pro if the compressor doesn’t start after testing – could be a bad starter relay.
