VCC3 1156 vs 2456: Read the Input Label Before Comparing Boards
Do not select a refrigerator inverter by the VCC3 family name or a few digits alone. When comparing markings such as 1156 and 2456, read the complete original label and the approved replacement information for the appliance. A code fragment is not a sufficient voltage specification.
Copy the label into separate fields
Record the complete VCC designation, suffix, numerical manufacturer code and the line explicitly marked Input. Keep the Output line separate. Photograph the original label clearly enough to verify characters later; a marketplace title may omit the important suffix.
Do not infer the required input from the output voltage. The two label fields describe different sides of the inverter's operation. Similarly, a current value needs its associated input or output context.
Build an application comparison
Ask a qualified service provider to compare the original and proposed inverter against the refrigerator model and compressor application. Connector shape, enclosure and mounting arrangement are additional checks, not substitutes for the electrical and control requirements.
The TSIGUOQURU listing is identified as VCC3 1156 M4 F 9B. That marking should not be shortened to a claim that every VCC3 board is compatible. Obtain an explicit application confirmation before ordering a different variant.
Stop at an unresolved field
If the label is unreadable or the service documentation does not establish the replacement, do not connect the board for a trial. Have the identification resolved first.
Disconnect power before access. Inverter electronics can retain hazardous energy, so label access and internal work should follow the qualified service procedure. Never try to run a variable-speed compressor directly from line power.
Product reference
Compare the VCC3 1156 M4 F 9B listing and product photographs with the complete appliance model before ordering. A symptom or similar appearance alone does not establish compatibility.
