Repair of household appliances is best left to a specialist
All brands of refrigerators have similar breakdowns, although they differ in operating principle. Restoring the appliance's functionality depends on the complexity of the situation. DIY repair can lead to more serious malfunctions that require more time and money to fix. Therefore, this issue should be handled by a professional refrigerator repair technician, who can fix the problem even at home.
Main problems with the refrigerator
1. The refrigerator does not turn on. This is a common type of breakdown that can have several causes. You need to ensure that voltage is supplied to the appliance, which depends on a working power cord, socket, and plug. You can check the voltage supply from the network using an indicator light. If it works, you need to analyze the condition of the thermostat. To assess its condition, connect the thermostat terminals together. If the refrigerator starts working, the cause is a faulty thermostat that needs to be replaced.
The next elements to check for the cause of the refrigerator not turning on are the start relay and the overload protector. This procedure requires special instruments.
Finally, the electric motor is checked. During diagnostics, it may reveal an open circuit in one of the windings, a short circuit to the housing, or between windings. The repair technician checks the electric motor with a megohmmeter to obtain reliable data.
Oxidized contacts in one of the connections can also lead to problems with the refrigerator turning on. If no faults are found during the inspection of key elements, a thorough examination of all connections should be carried out.
2. The refrigerator does not cool. Freon leakage occurs due to depressurization of the system. This cause can be identified by a cold condenser, which normally heats up to 70 degrees. A malfunction related to freon leakage is fixed at a service center.
The thermostat is responsible for organizing the operation of the refrigeration system. Malfunctions in its operation lead to partial or complete lack of cooling. If problems are detected in the thermostat, it must be replaced.
The refrigerator may cool poorly due to damaged door seals. They should be carefully inspected and replaced if defects are found.
