Technical support
Tell us what the unit is doing and we will work it through with you. If it is showing a code, check it against the fault list first — most faults name themselves, and the reset that clears them is published.
Before you write
It may already be answered
The support hub carries the fault and blink codes, the symptom-first troubleshooting, the installation guides and the full manual archive.
If the unit is faulty rather than misbehaving, the warranty page has the coverage terms and the RMA request.
Technical support
Describe the problem
The model number, what the unit is connected to and what it does when it fails are the three things that let us answer in one reply rather than three.
