Question

Refrigerator stops working after first cycle. Once I switch it on, the compressor works and condenser coils become hot, but after sometime, when the compressor restarts, the condenser coils remain cold. What seems to be the problem?

Answer 1

If your refrigerator stops working after the first cycle, and you notice that the compressor works, and the condenser coils become hot during the initial cycle but then remain cold after the compressor restarts, there could be several possible issues causing this problem. Here are some potential causes:

1. Overheating: The first cycle may be working fine, but if the compressor or another component is overheating, it could be triggering a safety mechanism that shuts down the refrigerator to prevent damage. This can be caused by a faulty thermostat, a blocked airflow around the condenser coils, or a malfunctioning fan that is supposed to cool the compressor or condenser.

2. Refrigerant leak: A refrigerant leak can cause the cooling process to be ineffective and may explain why the condenser coils are not getting hot during subsequent cycles. If the refrigerant level drops too low, the compressor will struggle to cool the refrigerator properly.

3. Compressor issues: The compressor itself might be faulty or failing. It could be starting fine but failing to maintain the necessary pressure to keep the cooling cycle going consistently.

4. Defrost system malfunction: Some refrigerators have a defrost system to prevent ice buildup on the evaporator coils. If the defrost system is malfunctioning, it could lead to improper cooling and affect the refrigerator's overall functionality.

5. Thermostat problems: The thermostat controls the refrigerator's cooling cycles. If it's not working correctly, it might not signal the compressor to turn on at the appropriate times, leading to inconsistent cooling.

6. Electrical issues: There could be electrical problems in the refrigerator's circuitry, such as faulty wiring or a damaged control board, which disrupt the proper functioning of the cooling system.

To determine the exact cause of the problem, it's best to have a professional appliance repair technician inspect and diagnose the refrigerator. They have the expertise and tools to identify the specific issue and perform the necessary repairs. Additionally, if your refrigerator is still under warranty, it's essential to contact the manufacturer or an authorized service center for assistance to avoid voiding the warranty.
