This advanced flow addresses deeper system interactions, requiring careful observation of multiple components working together.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- Due to the complexity, any further investigation into the electrical or refrigeration systems must be performed by a qualified technician.
- If the issue involves the main power supply or internal controls, a qualified technician is required for safe assessment.
