Quick check — and when it's not DIY
One thing you can rule out on your own: unplug it for a minute and try again, since a simple reset clears more faults than people expect. When that isn't the fix, if the basics check out, the fault is inside the control system or a sealed component, and diagnosing that safely takes a technician's tools and training.
