Does this guide apply to your appliance?
Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.

Likely causes
- The indicator meaning depends on the controller and model; use its user manual rather than diagnosing from colour alone.
What to try
Identify the display before choosing a remedy
Easy- Record the full model number from an accessible label and the controller model; do not open the appliance.
- Note the colour, steady/flashing pattern and any accompanying display code.
- Locate the indicator description in the exact model manual or ask Tornado support to identify it.
Use only accessible maintenance checks
Easy- Check the remote settings and batteries when the appliance is not responding.
- Clean a user-accessible filter only as described in the model manual; do not climb unsafely or remove internal covers.
- If cooling remains absent, a breaker trips again, or there is a burning smell or visible damage, stop using the appliance and request professional service.
This step is marked caution. Stop if you are not qualified to continue.
