Once in a while, you will out-rightly notice that something is wrong with any of your home appliances. For instance, you will notice that your refrigerator is not working well if it is producing odd noises or if it is not keeping your food cold as expected. Still the same, you do not have to be an appliance repairman to notice that your refrigerator has a problem when it won’t start. If everything relating to the power is fine, then your fridge may be having problems with its starting mechanism. Here are some of the issues that may lead to your refrigerator not starting.
Problems with Overload Relay or Starting Capacitor
The overload relay is one of the most important devices in a refrigerator. It often acts as a protective device in the compressor circuit of a fridge. The power that enters into the fridge’s compressor motor winding has to pass through the overload device before being relayed to start winding the compressor’s circuit until its running at the required speed. Nonetheless, if you notice that your fridge’s compressor won’t start or is producing a clicking sound, especially if the fans are running, then this should be a clear indication that the overload relay is either overheating or arcing. Do not forget that modern overload relays are always a combined unit commonly plugged into the compressor’s side. A starting capacitor may also be part of the overload’s assembly and becomes crucial in providing an increased starting voltage to the fridge’s compressor windings. A defective starting capacitor may make the fridge not to start properly and it is always advisable to replace it if necessary. Remember to carry out any service on these parts after unplugging the power source to prevent any electrical injury or damage.
Cold Control and Temperature Control
The cold control refers to a temperature controlled switch, which acts as the power supply to the compressor and the fan circuit. A defective cold control may lead to scenarios where the fans and the compressor are not running. In most cases, a temperature control adjustment knob is also attached to the cold control to aid in controlling the fridge’s temperature. When you notice defectiveness with your fridge’s temperature control, it is always advisable to remove the control panel, which is usually located in the fresh food section of the fridge. You should then remove the control device from its housing and disconnect the terminal leads. This should be followed with an adjustment of the cold and temperature control to a colder setting before reconnecting the terminals. If it’s still not working, then you should consider replacing the entire cold and temperature control unit.
Electronic Control Board
An electronic control board in a refrigerator acts as the monitor of the fridge’s temperature and the controlling station of the compressor. A defective electronic control board may lead to the fridge not starting and this may not be a good sign to your fridge as it is always complex and expensive. However, you should check all other external issues revolving around the fridge’s power supply and anything else, such as burnt or arcing connections, damaged foil and any other external control. Do not forget to disconnect your fridge from power while inspecting the electronic control board.
