My Xpelair 4" axial fan won’t turn off or constantly running?

If your fan in not switching off there could be a few different reasons why -

              1 – Is your fan an intermittent extract or constant volume (CV) fan. CV fans are designed to run continuously so they will never stop unless switched off at the isolator.

              2 – Does your fan have a Humidistat. If the rooms humidity level is above the setting on the fan, then it will run until the level drops 

              3 – Does your fan have a timer. Is it continuing to run beyond the set duration? If so, it could be due to something called induced voltage. This is usually where the wires for the power and timer trigger wire are in the same cable. When in use the power wires can generate a magnetic field which can result in a small amount of voltage being generated on the trigger wire, enough to start the fan and keep it running all the time it is there. 

              4 – Has the fan been wire correctly at the terminal block, specifically if it is a timer variant. They should be wired, live to live, neutral to neutral, and a switched live to the T terminal. However, if a permanent live has been wired to the T terminal the fan will continually run.

              5 – If none of the above resolve the issue, then there may be a fault with the product. If this is a new installation, then we would recommend seeking a replacement via the supplier initially. If product not recently installed and in guarantee please raise a ticket below.

If out of guarantee then a replacement product will be required to be purchased.
