Viking repair.
Professional-grade refrigeration demands professional-grade service. We keep Viking refrigeration cold, quiet and precise — and the range beside it lighting first time.
Two columns, two jobs — fresh food in one, frozen in the other, and each held at its own temperature.Viking built-in refrigerator and freezer columns
What We Service
Built-in & professional refrigerators
5 Series built-ins, side-by-side and all-refrigerator columns, and the Veil integrated columns.
Wine cellars
Single and dual-zone Viking wine units — stable temperature for serious collections.
Ice machines
Under-counter clear-ice machines — production, drainage and water supply faults.
Freezers
All-freezer columns and drawers — defrost, evaporator and door-seal issues.
Ranges & rangetops
Professional gas and dual-fuel ranges — burners, ignition and oven temperature. More on ranges and ovens.
Wall ovens
Single and double wall ovens — elements, convection, sensors and controls.
Inside a Viking
An inverter, not a switch.
The compressor in a modern Viking built-in is not simply switched on and off. It is driven by an inverter: line voltage arrives at the inverter from the high-voltage board, and a low-voltage board tells it how hard to run with a small DC signal. The compressor modulates rather than cycling.
Which is why "the compressor is dead" is so often wrong. A silent machine can just as easily be an inverter, a board, or a thermistor that has stopped reporting. Replacing a compressor that was never faulty is an expensive way to learn that.
One more thing worth knowing before you assume the worst: the control enforces a dwell time of several minutes before the compressor may restart, and it wants a temperature reading to hold steady for a beat before it acts. A unit that seems dead is sometimes a unit that is waiting.

A failed thermistor rarely announces itself. The section simply calls for cooling almost continuously, the unit runs and runs, and the only outward sign is a power bill and a compressor working harder than it should be.

Which Viking do you have?
The model number on the tag inside the cabinet names the series and the width — and the parts. Where to find it.
5 Series built-ins
42 and 48-inch built-in side-by-side, stainless or panel-ready (VCSB and FDSB prefixes), and the 30 and 36-inch built-in all-refrigerator columns (VCRB) whose service literature our notes draw on.
Veil integrated
Panel-ready columns that disappear into the cabinetry: all-refrigerator and all-freezer from 18 to 36 inches, a 36-inch bottom-freezer, and integrated wine cellars (FDREIC, FDFZIC, FDBMIC, FDWCIC).
3 Series
The 36-inch counter-depth French-door refrigerator.
Undercounter, wine cellars, ice machines
Undercounter refrigeration indoors and out, single and dual-zone wine cellars, and the clear-ice machines. More on wine storage.
Ranges and wall ovens
Professional gas and dual-fuel ranges and wall ovens — burners, ignition and oven temperature. More on ranges and ovens.

Viking questions
The Viking is silent. Is the compressor dead?
Often not. The compressor is inverter-driven: line voltage reaches the inverter from the high-voltage board, and a low-voltage board tells it how hard to run. A silent unit can be an inverter, a board or a thermistor that has stopped reporting — and the control enforces a six-minute dwell before the compressor may restart at all. We test in that order before a compressor is ever named.
What do the flashes on the inverter mean?
In Viking’s inverter literature one flash is normal operation, two flashes mean no signal from the control board, and three mean an open circuit on the compressor or inverter side. Our error-code page lists them; count the flashes and tell us.
Why is there water on the floor?
Defrost water runs to a pan and is dissipated by a pan heater that a float switch turns on. When the switch or the heater fails, or the drain is blocked, the water has nowhere to go but out.
Which Viking refrigeration do you repair?
5 Series built-ins, Veil integrated columns and wine cellars, the 3 Series French-door, undercounter units, wine cellars and ice machines — and the professional ranges and wall ovens beside them.
Are you an authorized Viking service?
No. Aphelion is independent and not affiliated with Viking Range, LLC. If your unit is still under Viking’s warranty, contact Viking first — a covered repair should cost you nothing.
