Auto mag zone seems to be stuck shut

Is it possible that the coil is bad or that the plunger is just stuck? What is this likely to be? You’re dealing with a pretty handy guy but I have zero experience with boilers. We moved to a new house.

    Replace the zone valve with a new one and it will give you years of use
