What 0 means on a Hisense

The self-check shows 0, which means no fault is stored. If the unit is still not running, the cause is something the board does not detect: a thermostat setting, a dirty filter, or a mode the outdoor temperature does not allow.

On this platform, 0 is a status, not a fault: the unit is telling you what it is doing; nothing is wrong.

When to call a technician

Which Hisense units show 0

This page applies to Hisense Hisense inverter single-zone and Hisense multi-zone units. Hisense's own documentation lists 0 as "No fault stored (normal)", the same definition used across the Hisense it is built on. If your unit shows a code with a different shape (for example a four-character code, or a plain number), it is from a different table; use the lookup with your exact code.

Where Hisense shows this code

Hisense inverter splits store the fault as a number. When the compressor has stopped on a fault, point the remote at the unit and press the SLEEP button 10 times within 10 seconds: the indoor display then shows the code (a second stored fault shows after four more presses). The Sleep, Timer and Running lamps also blink a pattern that matches the code. Newer models show the number on the display without the button sequence. Codes 1 to 21 are outdoor-unit faults and protections; 33 to 41 are indoor-unit faults. 0 means no fault is stored.
