KT-LCD3 / KT-LCD4 Display Error Codes & Problems
Displays made for KT (Kunteng) controllers. These pages cover the KT-LCD3 and KT-LCD4, whose manuals list "info" codes.
About the KT-LCD3 / LCD4
- When there's a fault, the display automatically shows a flashing code: a number followed by "info" (for example 03 info). You can't leave the code screen until the fault is fixed. Then it goes away by itself. source
- The manual doesn't mention an error history. source
- Other KT models (like the KT-LCD5 and KT-LCD8) aren't covered here. We couldn't find manuals with their code tables. If you have one, use the Not sure pages.
