Bosch Refrigerator: not starting
What is this symptom?
Is your Bosch refrigerator not starting? If it's not powering on, with no compressor or fans running, you could be facing a power issue or a faulty component. Let's explore the common causes and solutions to get your fridge cooling again.
Important Tips for Bosch Models
- Bosch models often integrate control boards for multiple subsystems, increasing complexity of internal electrical issues
Possible Causes
No power to fridge (outlet/circuit issue)
How to Identify: No lights or sounds from fridge; other appliances on same circuit may be affected if breaker tripped
Part: Home electrical circuit/outlet
Faulty power cord
How to Identify: Visible damage to cord, frayed insulation, or replacement fixes symptom for others
Part: Power cord
Defective electronic control board
How to Identify: No response when power applied, no control panel lights, confirmed faulty board in similar cases
Part: Electronic control board
Faulty thermostat/cold control
How to Identify: Fridge not activating even with correct power; temperature control may not respond
Part: Thermostat/cold control
Start relay or compressor issue
How to Identify: No start, possible clicking noises, but more complex diagnosis required
Part: Compressor/start relay
DIY Solutions

Check the power supply. Ensure the refrigerator is plugged in and that the circuit breaker hasn't tripped. If it has, reset it and check if the refrigerator starts.
-
Inspect the start relay. Unplug the refrigerator, locate the start relay (usually found on the compressor), and check for any signs of damage or burning. Replace if necessary.
-
Test the thermostat. Use a multimeter to check the thermostat for continuity. If it does not show continuity, replace it.
