Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: unplug it for a minute and try again, since a simple reset clears more faults than people expect. If it's still acting up after that, 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.
