Superior Service provides factory authorized commercial appliance repair backed by manufacturer certifications that protect your warranty coverage and equipment investment. Our technicians complete annual recertification through Rational, Hobart, Manitowoc, Pitco, Convotherm, Alto-Shaam, and Frymaster factory training programs. When your health inspector requests service documentation, our factory authorized commercial appliance repair work orders include manufacturer compliance stamps, calibration certificates, and OEM parts traceability that independent shops cannot provide. We carry technician ID cards from seven manufacturers and maintain direct parts accounts that get you genuine components, not aftermarket substitutes that void coverage.
Our factory trained technicians diagnose Rational SelfCookingCenter error code E010TR (core probe failure) with OEM part 60.00.560, repair Hobart AM15 dishwashers throwing E4 tank temperature faults using genuine heating elements, and rebuild Pitco SSH55 fryer gas valve assemblies per factory bulletin TB-2018-04. We follow manufacturer torque specifications, use OEM refrigerants for Manitowoc ice machines, and program Alto-Shaam CT PROformance combis with factory firmware updates. Every Convotherm OES mini repair includes the three-point combustion test required in our factory service manual. This is not generic appliance work. This is manufacturer-certified repair that keeps your warranty intact and your equipment compliant.

"Their Rational certification saved our warranty when our combi went down during Easter brunch. Factory parts arrived in two hours."
"We only use Superior for our Hobart equipment. Their factory authorization means health inspections never flag our dishwasher service records."
"Error code E027 on our Frymaster would have cost us lunch service. Their factory trained tech had the OEM high limit switch in stock."
