Technical description: No tacho from fan
What causes this fault?
This fault occurs when the boiler’s control board sends power to the fan but does not receive a signal back confirming that it is actually spinning. The most common reason is that the fan motor has seized or burnt out, though it can also be caused by loose electrical connections or a fault on the main circuit board itself.
This issue can be more frequent during the first cold spell of autumn, as fan bearings may seize up after being inactive throughout the summer months.
