Why Does Commercial Refrigerator Trip the Circuit Breaker?
Commercial refrigerators, whether used in businesses or homes, are essential appliances. However, during use, they may occasionally encounter issues that catch us off guard. One common problem is the commercial refrigerator tripping the circuit breaker. Below, I will explain the potential causes of this issue and provide corresponding solutions. Please read the following content carefully.
Reason 1: Compressor Malfunction
One of the main reasons for a commercial refrigerator to trip the circuit breaker is a malfunction in the compressor. To address this, you should first check the resistance value of the compressor’s start winding. If the resistance value is abnormal, it indicates that the compressor is damaged and needs to be replaced with a new one. If the resistance value is normal, but the refrigerator still trips the circuit breaker, you should inspect the compressor’s inlet and outlet.
Observe whether gas is entering or exiting during operation. If there is no gas flow, it is likely a compressor issue, and replacing the compressor is recommended.
Reason 2: External Unit Problems
Another possible cause is an issue with the external unit of the refrigerator. This situation often arises when the refrigerator can cool normally when turned on, but trips the circuit breaker once the compressor starts working. If the internal unit operates normally on its own, the problem likely lies with the external unit. In this case, you should check the resistance of the power cord in the external unit to see if there is a short circuit.
Additionally, inspect the capacitors involved in the machine’s operation. If a capacitor is damaged and causing a short circuit, it is advisable to replace it. You can also test the system to confirm if the capacitor is the issue (if the system operates normally during testing, the capacitor is likely faulty).
Reason 3: Sudden Start-Up Load on the Compressor
A sudden start-up load on the compressor can also cause the circuit breaker to trip. This is because the initial current draw when the refrigerator starts is 4 to 6 times higher than during normal operation. In some cases, this load can cause the breaker to trip, which is a relatively common occurrence. Over time, as the compressor ages, this issue may become more frequent, leading to tripping.
