When to call a technician

If the code returns after a reset, a technician needs to test and usually replace the sensor. It is a common, low-cost repair.

Safety first

Always switch off at the wall socket or MCB before touching any part. Do not open the outdoor unit, control boards or gas pipes yourself — they carry high voltage and pressure.
