driver 7240 humming- not alarm..

[jcono]

Hello-

Trying to figure the reason why a 7240 driver won't run a 6000 pump.

When plugged in, the driver makes a slight humming noise- but it isn't the alarm sound- and the pump won't go.


Reason I'd like to figure this out myself is because I am aware these units are no longer being repaired by Tunze, and I can't buy a new pump / driver at this time.


Any ideas would be appreciated
thanks,
Jano

Check if the driver gets hot at the bracket, if so it needs a driver replacement.
