Winter 2023 Update: Since December 2022 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at York MRO have been able to ramp up our service response times with expedited shipment schedules back to normal, providing replacement parts and services following normal response times. Our departments are now working on near-normal production levels and our delivery and service schedules back to regular operation levels. In addition to the Square D PMDH parts and service support, we have been able to add new lines of product and service:

Starting Q1 2023 York MRO is pleased to announce additional repair and rebuild services for the automation products made by industrial controls leader Struthers-Dunn such as the 237XBXP20 spares. Related to this we have added to our service line-up the 7022PC manufactured by Te-Connectivity and we are pleased to be able to service most Te-Connectivity systems and parts.
