Need some help from someone who is familiar with these boilers. The fan in this developed out-of-balance problems resulting in very noisy operation and vibration.
This was replaced with a new fan which lasted for about 5 hours and then stopped.
The voltage from the fan transformer on blue and red wires is supposed to be 24V dc according to the manual, it actually measured around 35V when I checked it. (The fan is a dc speed controlled job which blows the gas/air into the burner.)
We put the old fan back in and this works perfectly (apart from the vibration problems mentioned)and seems happy on the 35 or so volts. We are now awaiting an exchange for the faulty new fan but I wonder if the apparent over-voltage from the transformer might have caused the fault.
So before we chance plugging in the new unit does anyone have any advice?
Many thanks.
