Current sensor error

What does UH mean?

Abnormal if the current sensor detects -1.0 A to 1.0 A during compressor operation. This error indicates a potential issue with the current sensor circuit itself or the compressor's wiring. If left unaddressed, it can lead to improper compressor control, reduced efficiency, or even damage due to lack of accurate current feedback.
