Anyone else getting a lot of failures on new(ish) 3008646 PECs ?
I've just had to change yet another on my own boiler and had quite a few in the last couple of months...

Had a couple go in last few weeks on newish boilers, but nothing out of the ordinary. Held beside a new one in same light the resistances are very different. For such a big lump you would think they'd last longer!
