9 Troubleshooting
9.1 Testing Controllers
Before contacting the service department please follow the steps below to
determine if there is actually a fault, and if so, if a fault is within the blanket or
within the controller. This will make it easier when talking to the service
department.
Please also refer to the Troubleshooting Table on the next page for additional
information prior to contacting the service department.
• Remove the “good” controller, which you know functions correctly from the other
side of the blanket (excluding all single size blankets as these only have the one
controller), and test it on the “trouble side” of the blanket to determine if it is the
original controller or the blanket element which is at fault.
Please allow the “good” controller to be tested overnight as it may take a few hours
for any fault to show up. It is possible that the “good” controller may function for a
few hours prior to failing so it is important that the test be performed overnight and
not just for a few minutes.
• If after the overnight test, the controller is still functioning (i.e. the lights on the front
display are showing) and the blanket is heating properly, it can be concluded that
the original controller is faulty.
If this is the case, please call the service department for a replacement controller.
The model number of the controller is moulded into the back of the controller.
• If the “good” controller also stops functioning (No Lights on front display) during
the overnight test, and the Red light is showing through the back of the controller
(refer Overheat / Element Protection Section), it can be concluded that the blanket
element has been permanently damaged during use.
If this is the case, ordering a new controller will not help as it is the damaged
blanket element causing the safety devices in the controller to activate. The
blanket and controllers cannot be repaired.
• If the “good” controller, when tested on the “Trouble Side” of the blanket is found
to be still functioning properly (i.e. the lights on the front display are showing) after
the overnight test, but the blanket is not heating, it can be concluded that the
blanket element is faulty.
If this is the case, and if the blanket is still within the warranty period, please return
the blanket to the retailer. If returning the blanket, we please ask that:
o The unit is packed carefully back into its original packaging.
o Original proof of purchase is attached.
o A brief note attached to the blanket explaining the reason why it is being returned.
