Hi Pat,
If you still need support, you can complete a quick technical support form at the bottom of the main combilift.com web site or direct link https://warranty.combilift.net/technical-support-form/. The form only asks for the minimal info so the team can quickly help you. There is no login required and no charge for this support.
Combilift has Technical support technicians based in Combilift North America Headquarters, in Greenboro, NC, will respond.
You can also request access to the Knowledgebase where you will find more information available. Hope you get sorted.
