Built Around Two Brands
A Sub-Zero and Wolf Shop First, a Full-Line Shop Second
Repair cost depends on diagnosis, parts, and the approved scope. We do not. Sub-Zero uses two independent sealed systems, magnetic door gaskets, and microprocessor controls that reward a technician who has opened a hundred of them. Wolf ranges and ovens run dual-stacked burners, spark-to-sense ignition, and convection systems that need calibration, not guesswork.
- Dual sealed-system diagnosis on Sub-Zero built-in and integrated units
- Wolf burner, igniter, and oven control repair with proper calibration
- Wine storage, ice makers, and undercounter refrigeration by Sub-Zero and Cove
- Full-line support for Thermador, Viking, Miele, Gaggenau, Bosch, and more

Symptoms We Hear Most
Common Problems, Plainly Explained
Refrigerator Is Not Cooling
A Sub-Zero that runs warm often points to a condenser choked with dust, a failed evaporator fan, or a sealed-system charge that has dropped. We confirm which system on a dual-compressor unit is affected before quoting. Read more →
Ice Maker Stopped Producing
No ice usually traces to the water inlet valve, a frozen fill tube, or a harvest sensor that has drifted. On clear-ice modules the cause can be a stalled water pump. Read more →
Water Is Pooling Under the Unit
Leaks come from a clogged defrost drain, a cracked water line, or a door that no longer seals. We find the source rather than just wiping it up. Read more →
Strange Noises from the Appliance
Buzzing, clicking, or grinding can mean a worn evaporator fan bearing, a failing compressor mount, or ice striking a fan blade. The sound tells us where to look. Read more →
Temperature Keeps Fluctuating
Swings often come from a failing thermistor, a door left ajar by a tired gasket, or a control board reading the wrong sensor value. Read more →
Frost Building Up Inside
Excess frost points to a defrost heater, defrost thermostat, or control failure, or to a door seal letting humid air in. Read more →
Burner Will Not Ignite
A Wolf burner that clicks without lighting usually has a dirty or misaligned igniter, a wet burner cap, or a spark module that has failed. Read more →
Oven Will Not Heat
No heat can be a failed bake element, a gas safety valve, a relay on the control board, or a thermostat reading out of range. Read more →
