Daikin AC FAQs

Common questions about servicing, error codes, and maintenance for Daikin air conditioners.

U4 indicates a loss of data transmission between the indoor unit and outdoor inverter PCB. Our technicians inspect the wiring harness, signal noise, and printed circuit board transceivers on-site.

Due to high humidity and salinity in Kochi, Daikin ACs should undergo deep foam cleaning every 3 to 4 months to protect the titanium apatite filters and heat exchanger fins.
