problem with a Honeywell fan control

Hi, need help!! I have a Burnham direct vent gas boiler with a Weil- Mclain gold plus hot water expansion tank .
The transformer on the Fan relay assembly, R8285D 5001 burned out. I replaced the assembly only to have the new transformer heat up and burn out in about 30 seconds, right before my eyes (saw the puff of smoke).
Circulator continues to pump cold water through the expansion tank. Of course the boiler never comes on.
There are no visable defects.
thank you.

problem with a Honeywell fan control
is it likley there is a problem with the auto ignition system, Honeywell continuous retry S8670E ? any help out there?0 -
That relay
has N/O contacts, so if there is not a 24V signal (to the coil within the relay) your circ should not operate.
Contact 4&6 have a different amp rating, so they should be used for the 24V side.
Contact 1&3 is used for the 120V circ.
Be careful the wiring doesn`t get screwed-up. ;-)0 -
burnt xformer
Possible the xformer is undersized.But ,I,would add an inline fuse or circuit breaker,then ,use an ampmeter /multimeter to track down the cause of the problem.I do have a smoke catcher for sale!!0
