Condenser Coil Cleaning Check
This check assesses the cleanliness of the cooling coils and the airflow around them, as poor cooling is a primary cause of operational failure.
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.
- Oil residue found on condenser coil: Stop and escalate - possible refrigerant leak in sealed system.
- Fan motor hot to touch or making grinding noise: Disconnect power and escalate to technician.
- If oil residue is found on the condenser coil, service must be escalated to a qualified technician due to potential refrigerant leaks in the sealed system.
- If the fan motor is suspect, service must be escalated to a qualified technician for safe power disconnection and inspection.

Where to find this
Use this as orientation before touching the machine. It is location help, not a repair instruction.
Start at the front door payment column; match the display, keypad, coin, bill, or card device to the symptom before opening deeper panels.
- Central logic system managing vend sequences, refrigeration control, payment validation, and sales data. This machine may use one of two controller families depending on display type.
- Main controller board
- Controller housing
- Firmware chip or module
Do not open sealed-system or compressor areas unless a qualified refrigeration technician is handling the work.
