If an old refrigerator has been converted to a freezer-only unit without the compressor working, there are a few signs you can look for to identify the modification:
Temperature: Check the temperature inside the unit. If it has been converted to a freezer, the temperature should be significantly colder than a regular refrigerator. Use a thermometer to measure the temperature inside the compartment to verify if it is at freezing levels or below.
Door Seals: Inspect the door seals carefully. A freezer requires a tight seal to maintain the cold temperature. If the door seals are not properly intact, it might not be able to maintain the freezing temperature efficiently.
Interior Layout: Look inside the unit to see if the interior layout has been changed to accommodate the conversion to a freezer. A freezer usually has shelves and compartments designed for freezing and storing frozen items, rather than the configuration of a refrigerator with designated fresh food storage areas.
Defrost System: Check if the refrigerator has a functional defrost system. Freezers need a defrost system to prevent excessive ice buildup, which could impede cooling performance. If the defrost system is not functioning correctly, it might hinder the unit's ability to maintain the desired freezer temperature.
Condenser and Evaporator Coils: Examine the back or bottom of the refrigerator to locate the condenser and evaporator coils. In a converted freezer, you might find modifications to these components. For instance, there could be additional insulation or adjustments made to optimize the cooling for the freezer section.
Compressor Sound and Vibration: In a functional freezer, you should hear the compressor running periodically to maintain the low temperature. If the compressor is not working, you won't hear any sound or feel any vibration coming from the unit, indicating that it is not operational.
Modified Controls: Look for any modifications made to the controls or thermostat settings. If it has been converted to a freezer-only, the controls might be set to maintain freezing temperatures.
It's important to note that converting a refrigerator to a freezer without a functioning compressor is a complex and potentially risky modification. A properly functioning compressor is crucial for efficient cooling and temperature control. Attempting such modifications without proper knowledge and expertise can lead to safety hazards, inefficient cooling, and increased energy consumption.
If you suspect that a refrigerator has been converted to a freezer without a working compressor, it's best to have it inspected by a qualified appliance technician. They can assess the modifications, determine the unit's safety and efficiency, and recommend any necessary repairs or adjustments.
