Noticed radiators in room were warm and thermostats was off. Inspected the valve and suspect it was completely closed. Then I turned on the thermostat (yellow light for tstat cones on) and the valve opened...kind off...but the zone valve light (red) didn't come on and the boiler and pump didn't turn on.
I suspect I have a bad zone valve that won't close all the way and when the Tstat calls for heat the valve is not activating the switch to turn on the boiler and pump.

So will replacing the valve fix both not closing all the way and when turned on, activating the boiler and pump?
thanks

update: I am now getting both zone and thermostat lights to come on and the valve opens. The main issue is that when I turn off the thermostat the valve doesn't close all the way. Assume the motor needs to be replaced?
