The “Choked Lungs” of GIDC
The H6 Error is specific to the Indoor Fan Motor being “Locked.” Unlike electrical faults, this is often physical. The motor is trying to spin, but something is holding it back.
Why GIDC Areas? In industrial zones (GIDC), the air is filled with sticky chemical particles, textile fibers, or heavy dust. This “sludge” coats the rubber bush and steel bearings of the blower motor, acting like glue. Eventually, the motor seizes up, triggering H6.

The Stiffness Test
With AC OFF, open the flap. Push the roller with a pen. If it feels heavy, sticky, or hard to rotate, the bushes are jammed with dust.
Foreign Objects
Sometimes, a piece of packaging foam or a lizard/rat can physically wedge itself between the blower blades and the chassis.
It Spins, But H6 Appears?
If the fan spins freely by hand but the error persists, the Hall Sensor (speed counter) inside the motor is dead. The PCB thinks the fan is stopped.
Atlas Aircon Repair Protocol
Industrial Standard Repair Steps:
-
01.
Jet Pump Service (Deep Clean) We disassemble the blower unit and pressure wash the bearings/bushes to remove the “GIDC sludge.” 70% of H6 cases are fixed here.
-
02.
Bush & Bearing Replacement If cleaning doesn’t work, the rubber bush is deformed. We replace the bush set to restore smooth rotation.
-
03.
Feedback Sensor/Motor Change If the motor is electrically dead or the feedback wire is cut (rat bite), the entire motor unit is replaced.
