Hi - hope someone can help. Before Christmas we heard a buzzing noise from our ZA6 Drayton ZV Actuator. I confess to not understanding how these things work - but nudged it slightly and it stopped.
A month later we have a power cut and the same buzzing noise has happened again when the power returned.
I switched the heating off and then on again and it the buzzing has stopped for the time being.
The heating seems to be okay - but I'm keen to understand what it causing the noise. When it is buzzing, if I press or hold the ZVA a certain way the buzzing stops, and starts again when I let go.
Any idea - is it serious - or is it the motor inside that needs replacing?
Thanks in advance
