Questions and answers
Hi, I have problems the alarm is over current and compressor is working about 10sec went i replace sspm board the compressor is not working event 10sec. Can you help me, thanks
An overcurrent alarm and compressor failure in a FRIGOMAR CU50VFD after replacing the SSPM board could be caused by high resistance due to corroded, bent, or worn connectors. This leads to overheating, which increases power drop and can trigger overcurrent conditions. Additionally, if the flow switch is not functioning properly and the compressor runs without adequate water flow, it can also cause compressor failure.
