When your Daikin AC stops cooling, displays an error code on the wireless controller, or leaks water, our local Tenkasi technicians provide prompt doorstep diagnostics, PCB repairs, sensor replacements, and pressure jet cleaning across Tenkasi and Tenkasi district.
From sudden cooling drops and gas leaks to inverter PCB error codes, here are typical Daikin faults our technicians fix at your doorstep.
The operation indicator on the indoor unit blinks steadily and the AC cuts off cooling. By holding the remote cancel button, we retrieve diagnostic fault codes (e.g., U4, A6, C4) to pinpoint the circuit issue.
Water drips down the wall behind the indoor unit. Caused by a clogged drain pan outlet, algae slime in the drain hose, or improper back-plate level alignment.
The outdoor unit fails to start because signal communication between indoor and outdoor PCBs is interrupted. We check interconnecting control wiring and outdoor inverter board power circuits.
The outdoor fan motor stalls, causing condenser temperature to rise rapidly until the compressor trips on thermal protection. We replace faulty outdoor DC fan motors and capacitors.
Gradual cooling drop over weeks with oil marks on copper flare joints. We perform nitrogen pressure leak testing, silver brazing, deep vacuumization, and exact R32 gas recharging.
The motorized horizontal airflow louver fails to open or remains stuck midway. Caused by a stripped stepper motor gear. We install fresh Daikin louver stepper motors.

Daikin air conditioners rely heavily on pure R32 refrigerant. Because R32 operates at high operating pressures, flare connections at outdoor service valves must be torqued precisely. If your Daikin AC loses cooling, our technicians perform nitrogen leak testing at 250 PSI, re-flare copper lines using eccentric flaring tools, evacuate with a two-stage vacuum pump down to 500 microns, and charge R32 by exact gram weight.
Daikin evaporator coils feature high-density hydrophilic aluminum fins and micro-louvers. Ordinary water splashing bends the delicate fins and pushes dust deeper. Our specialized jet wash mounts a waterproof collection funnel, applies neutral foam cleaner, and flushes the cross-flow blower and cooling coil at calibrated water pressure.
Our technicians bring specialized waterproof wash jackets, eco-safe coil cleaning foams, and pressure wash machines. We thoroughly flush the cooling fins, clear mold from the condensate drain pan, blow through the drain hose to prevent indoor water dripping, and spray outdoor condenser fins clean.
