Heat link is dead

hmferris — Tue, 07 Mar 2023 10:10:18 GMT

My heat link is completely dead very suddenly. There is no LED light on the heat link and I've tried to reset it. I have checked the fuses and there are no issues - I have a second heat link beside the dead one for different rooms in the house and it is working fine. I have looked at other threads and have pasted in the questions asked on them with my responses in blue. Any help greatly appreciated in this cold snap in the UK!

Are there any lights on the Heat Link? Does the boiler activate when calling for heat by pressing the Heat Link's button to activate Manual Mode? No
Are you seeing any wiring report or error on the thermostat and/or the app? "H72 HEAT LINK The power to this thermostat is off"
Have you had any recent power cuts in your area? If yes, has the power been restored? No recent power cuts
Have you recently had service or maintenance on your electrical, plumbing, or heating system? No
If yes, how long was the power off for? (Be specific.) N/A

Could you tell us please if you've checked on the breaker switch and fuse box? Yes
Any blown fuse in there? Have you tried to turn the breaker switch off and on again? Any difference? No blown fuse
