Downstairs heatlink no lights on

Community Member

Just noticed that our downstairs heatlink has no lights on it. The heatlink for the one upstairs is working fine. I’ve turn the power off and back on and had our friend who an electrician to check there is power getting to it, there is.

  • Does anything happen if you press its button for 30 seconds?   Nothing
  • In some cases the boiler will have an additional isolation switch which can turn off the power to both the Heat Link and the boiler. Can you try switching that off/on again to see if anything changes?  Done – no change
  • Make sure the breakers are on or the fuse board hasn't tripped.  Reset everything – No Change
