- Type of code
- Fault
- Urgency: Worth keeping an eye on
- First safe check
- Run the louvre through its full travel from the controller and watch it, because if it moves for part of the travel the motor is probably good and something is binding.
What A7 means on this model
The louvre is not moving as commanded. The operation lamp stays lit rather than blinking, so the system keeps heating and cooling and only loses the ability to aim the air. The manual still asks for it to be checked and repaired.
Symptoms you will notice
- Indoor unit shows A7 with the operation lamp lit rather than blinking
- Heating and cooling still work
- The louvre is stuck in one position or does not move
- Heating or cooling feels uneven across the room
Common causes
The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:
- A failed swing flap motor
- A louvre mechanism that is obstructed or out of alignment
- A wiring fault to the louvre motor
- A louvre that has been forced or bent during cleaning or installation
What you can safely check
These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.
- Run the louvre through its full travel from the controller and watch it, because if it moves for part of the travel the motor is probably good and something is binding.
- Look for a bent or forced louvre, which is common after someone has cleaned the unit and pushed the vanes.
- Check that the louvre is not obstructed by a filter that has been fitted incorrectly.
Do not do these
- ×Do not force the louvre by hand, since that is what bends the vanes and turns a motor fault into a replacement louvre.
- ×Do not take the indoor unit apart to free a swing flap with the power switch on.
When to call a technician
No call needed yet, but write it down
Note the date and the exact code, and watch whether it comes back. If it turns into a repeat fault or starts affecting performance, that is when it becomes worth a technician.
- The refrigerant circuit is sealed and legally requires licensed handling. Opening it without certification releases refrigerant and can put the whole system in violation of regulation, so a low-pressure or high-pressure fault on this equipment is a call-out, not a weekend job.
- If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.
A technician job for the motor. A homeowner can watch the louvre travel and look for a bent vane.
