Daniel Harrison

Daniel Harrison is a lead appliance repair specialist and technical writer with 17 years of hands-on experience servicing Viking, Sub-Zero, and other premium residential appliances across the eastern United States. He holds EPA Section 608 Universal Certification and NASTeC credentials, and has completed Viking factory training programs covering Professional Series ranges, dual-fuel ovens, built-in refrigeration, and ventilation systems. Over his career, Daniel has logged more than 8,000 service calls on Viking appliances, including warranty work and complex sealed-system repairs at authorized service centers in Philadelphia and Baltimore.

At Viking Repair Guide, Daniel writes in-depth troubleshooting guides, error code references, and repair cost breakdowns for homeowners navigating issues with Viking Professional, Viking 5 Series, and Viking 3 Series product lines. He personally tests every diagnostic procedure against Viking technical service bulletins and wiring schematics before publishing. His methodology pairs field-tested repair sequences with clear step-by-step instructions, giving readers a reliable path from symptom identification to resolution — whether that means a confident DIY fix or knowing exactly what to tell a licensed technician.

Daniel believes that transparent, technically accurate repair information helps homeowners protect their investment in Viking appliances. His content emphasizes realistic parts and labor cost expectations, clear decision points between DIY and professional service, and a safety-first approach to gas and electrical troubleshooting. Outside of work, he mentors apprentice technicians at a Philadelphia-area trade school and volunteers with a local nonprofit refurbishing commercial kitchen equipment for community organizations.
