Boiler Controls Not Responding
Unresponsive controls point to the PCB, wiring or a power issue.
When the boiler's buttons or display don't respond, a control fault is likely.
Common causes
A failing PCB, loose wiring, or a power-supply issue can make the controls unresponsive.
What to do
Cycle the power once; if the controls stay unresponsive, the PCB or wiring needs a technician.
Key takeaways
- Cycle power once
- Unresponsive controls = PCB/wiring
- Don't open the boiler yourself
- Needs technician diagnosis
