When you see a E152 error code the error essentially occurs when there is an issue with the indoor unit expansion valve but, don’t forget to check the sensors resistance values before condemning the expansion valve. An out of range sensor may not throw a sensor error but it can cause the systems logic to make a wrong judgment.
