Machine Completely Dead — No Power

Machine Completely Dead — No Power
Step-by-step diagnosis for a vendor that shows no signs of electrical life. Starts at the wall outlet and works inward. Stops before any live-voltage measurement.
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.
- Burning smell or visible scorching detected: Unplug immediately. Do not probe further. Escalate to licensed technician.

- 1
Verify Wall Outlet Power
operator-intermediatelowPlug a known-good lamp or outlet tester into the same wall outlet the vendor uses. Confirm the outlet is live.
Expected: Outlet tester or lamp indicates power is present.
Evidence to note: note
- 2
Inspect Power Cord
operator-intermediatelowWith the machine unplugged, visually inspect the full length of the power cord for cuts, kinks, burn marks, or melted insulation. Check the plug for bent or damaged prongs.
Stop conditions- Cord is cut or melted — do not plug in
Expected: Power cord and plug are visually intact with no damage.

Check Internal Fuse or Breaker
operator-intermediatehighWith the machine unplugged, locate the fuse holder or breaker on the machine. Remove and inspect the fuse visually. If a multimeter is available, check continuity.
Stop conditions- Fuse blown repeatedly after replacement — do not keep replacing, escalate
Expected: Fuse element is intact and continuity is confirmed.
Evidence to note: meter-reading
- 4
Inspect Terminal Block Connections
operator-intermediatehighWith machine unplugged, visually inspect the terminal block where the power cord connects inside the machine. Look for loose wires, discoloration, or melted insulation.
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.
Stop conditions- Discoloration or melting visible — do not re-energize until repaired
Expected: All terminal connections are tight, clean, and show no heat damage.

- 5
Listen for Compressor Operation
operator-intermediatelowWith the machine plugged in and thermostat set to coldest position, listen near the lower rear of the cabinet for compressor hum or vibration. A quiet compressor may still be running.
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.
Stop conditions- Clicking sound from compressor repeatedly — potential thermal overload, do not keep cycling
Expected: Steady low hum or mild vibration indicating compressor is running.
Evidence to note: note
- 6
Check Condenser Cleanliness and Airflow
operator-intermediatelowWith machine unplugged, inspect the condenser coil area (typically at the lower rear or bottom) for accumulated dust, lint, or debris. Ensure there is adequate clearance around the machine for air circulation.
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.
Expected: Condenser fins are visibly clean with open air passages.

- 7
Inspect Door Gasket Seal
operator-intermediatelowClose the main door on a dollar bill or thin paper strip at several points around the perimeter. Gently pull — there should be light resistance indicating the seal is engaging.
Expected: Paper has slight drag at all test points around the door perimeter.
Evidence to note: note
- 8
Check Evaporator Fan Operation
operator-intermediatelowWith the machine running and compressor confirmed active, listen for evaporator fan airflow inside the cabinet. Feel for gentle air movement near the evaporator cover.
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.
Expected: Air is moving inside the cabinet when compressor is running.
