Common fridge faults
When your refrigerator breaks down it can ruin your day! What if you wake up one morning and open your fridge, only to discover that your favourite milk has gone off or that the chocolate icing on the cake you baked for your best friend’s birthday has melted. It can be a panicky situation but don’t worry. Here are the most common causes that will cause your fridge to malfunction.
1. Faulty Overload Relay and/or Relay Start Capacitor
The overload relay is basically a protection mechanism that is situated in the compressor circuit of your fridge. The compressor motor starts through the overload relay; the relay adds the start winding of the compressor motor in the circuit until the compressor reaches a steady speed. If you find out that the fan is running but the compressor is not starting up, then you need to check the relay for any symptoms of arcing or overheating. Additionally, you may hear a clicking sound as well. You can utilise a multimeter to ensure continuity in the overload relay.
Another cause might be a faulty capacitor. It is located within the overload relay assembly and its function is to supply the compressor with an increased starting voltage. If this capacitor is defective, then the compressor may not be able to start. You need to check it for signs of arcing or overheating and replace it, if necessary.
2. Defective Temperature Control Switch
The temperature control switch or cold control is a switch that provides power to the compressor motor and the fan motor in your fridge. You might have observed a temperature knob in the food section of your refrigerator; that is what controls this switch. If your fridge is not starting, then this switch has developed a fault. Unplug the main power and disassemble the temperature switch.
You will need to test out the switch by turning the knob to a colder setting. If the switch closes, then there is nothing wrong with it. But if it doesn’t, the control has a fault and will need replacement.
3. Faulty Electronic Board
Many modern fridges are controlled by a central electronic circuit board that monitors and adjusts the temperature automatically and controls the defrost system, compressor and various fans. In some cases, this board can develop faults as well and cause your fridge to stop functioning. However, you need to realise the fact these circuits are quite expensive and complex in nature.
Before turning your attention towards it, you need to check if the circuit board is receiving electrical power, if the external functions are working, and whether the compressor is receiving any power at all. Disconnect the main power and inspect the electronic control circuit board for any burnt-out connections, arcing, or damaged foil. If you are unable to understand the circuit, you can hire a qualified service technician to do so.
