Power Input Diagnostic
Systematic verification of power delivery from wall outlet through machine internal power distribution.
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.

- 1
Verify Wall Outlet Power
operator-intermediatelowUsing a known-good lamp or outlet tester, confirm the wall outlet providing power to the machine is active and supplying correct voltage.
Outlet / Circuit TesterExpected: Outlet tester or lamp confirms power is present at the wall.
Evidence to note: meter-reading
- 2
Inspect Power Cord
operator-intermediatelowVisually and physically inspect the full length of the machine power cord from plug to machine entry point. Feel for soft spots, look for discoloration or damage.
Flashlight or Work LightStop conditions- If cord is damaged, do not plug machine in until cord is replaced
Expected: Cord is intact with no visible damage.
Evidence to note: photo
- 3
Check Main Fuse or Breaker
operator-intermediatemediumLocate the main fuse or circuit breaker on the machine. If a breaker, verify it is in the ON position. If a fuse, visually inspect or test for continuity (with power disconnected).
Digital MultimeterStop conditions- If fuse has blown, investigate root cause before replacing — a blown fuse indicates a fault
Expected: Fuse shows continuity or breaker is in ON position.
Evidence to note: meter-reading

Verify Voltage at Machine Power Entry
technician-advancedlive-voltageWith machine plugged in and power confirmed at wall, carefully measure voltage at the machine's power entry terminals (terminal block or power entry module). Requires line-voltage measurement skill.
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.
Digital MultimeterStop conditions- If uncertain about measuring line voltage safely, stop and hand off
Expected: Voltage present at machine power entry matching machine nameplate rating.
Evidence to note: meter-reading

Check Low-Voltage Supply Output
technician-advancedlive-voltageIf accessible, measure the low-voltage DC output from the power supply section that feeds the controller. Location and expected voltage requireOfficialSource.
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.
Digital MultimeterStop conditions- If low-voltage section shows signs of overheating or component damage, stop and hand off
Evidence to note: meter-reading
