Complete Power Failure Diagnosis
Vendo GPL 159, GPL 160
Complete Power Failure Diagnosis
This procedure helps isolate whether the power loss is occurring at the main service connection or within the machine's internal electrical infrastructure.
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.
- Live voltage present but no internal power: Escalate to manufacturer-or-licensed technician if internal wiring is compromised.
- Because this involves live-voltage checks and internal wiring, you must escalate this immediately to a qualified technician. Do not proceed with internal power checks.

Location Help
Where to find this
Use this as orientation before touching the machine. It is location help, not a repair instruction.
Start outside the machine at the outlet and cord, then identify the power entry area before any protected-compartment inspection.
- Wall outlet, power cord, power entry, and terminal area
Do not open energized or protected electrical areas unless a qualified technician or licensed electrician is handling the work.
