The Diamond H controllers are one of the earliest electronic control units for the 30Amp Electric Aga range. Provided that the internal electronic assemblies are in reasonable shape the unit can be refurbished in our workshop. During refurbishment we change any faulty parts and also fix any operational faults. For the refurbishment to be viable the internal printed circuit board assemblies have to be in reasonable condition without any significant mechanical damage or burning. Prior to return of your repaired controller we fully test the operation performance of the Aga control circuits and record these on a test document. The Diamond H 30 Amp Aga controller uses a Triac (type BTA40600) switch mounted in the body of the oven to control the Aga Core. When sending your controller for repair please return the Triac (type BTA40600) and we will check this out as part of the refurbishment.
After refurbishment for your peace of mind we give a full 18 month warranty of our work on your controller.
