Dreamland Electric Blanket Controllers (Garston L19)

The controllers are off a 'Dreamland Intelliheat' electric under blanket (see photo). The actual blanket is faulty and beyond economical repair. However the conrollers are still working correctly and, if you own one of these blankets
they are worth having as a spare because a new Dreamland replacement controller costs £29.99. The controller Model Number is H58A1 (see photo showing highlighted Model Number on the rear of the controller).
Please check the Model Number of your existing controller is the same, as the controllers differ for different electric blankets models.
