Hi, I have noticed recently that there is a loud whooshing noise coming directly from the TRV , when up at 5, turned it down to 4 and the head of the valve slowly turns back to 5? Weird, radiator was bled about 6 months ago.....any ideas? TRV Need changed?

New head required if it opens itself.
Don’t rely on trvs to control overall temperature.
