Central Boiler / Re: Central Boiler air flow door solenoid

I borrowed a tester just now and get a zero reading, so I guess its fried. Just not impressed as it was new 3 months ago.

I can open and close the air door by hand, no resistance. The last solenoid I replaced was jammed and wouldn't move. I replaced the fuse with the same one as before. I was going to take the solenoid back tomorrow and see if they will replace it.

Central Boiler / Central Boiler air flow door solenoid

I had to replace the air flow door control solenoid about 3 months ago as it was bad. Fitted the new one and everything was fine. This morning however, the control fuse for the solenoid had blown and so no air flow and no heat. I replaced the fuse but it popped as soon as I turned power back on. I disconnected the wires to the solenoid and replaced the fuse again. All good until I reconnected the wires and the fuse popped again. What would cause the new solenoid to go bad in 3 months. Seems they should last longer.
