I know that a TRV can become stuck closed, hence always cold, and that they might be freeable quite easily. Is it possible for the TRV to get stuck open, and that there is a similarly easy fix? There is a kids room that is always boiling and closing the TRV apparently does nothing.
TRV is always hot. Broken?

The pin can get stuck up as well as down.
Remove the head and check that the pin will go down when pressed and spring up when released. If sticky, try a little WD40 or silicon lubricant.
