I have a large combined storage / convector heater in the lounge, the
output dial is stuck or at least I think it is. I have taken the dial
cover off and there is a metal ring around the semi-circle knob, the
ring has plastic bits holding the knob in place. I took this bits out
and the metal ring came out as well, I tried to turn the knob and it
Is the metal ring thing supposed to have bits of plastic holding it in
place, I am thinking the plastic bits are there by design rather than a
build up of dirt?
How do I get the knob to turn ? Is it supposed to turn ?
Any thoughts on the black art of storage heaters are greatly
I'm not entirely clear what you are asking but this may help:
The output control on a storage heater is a mechanical arrangement which
operates an air control flap. The higher the output number the more open
the flap should be and the greater the airflow that is allowed to pass over
the hot bricks. Tracing the mechanical linkage back from the flap to the
dial may help you understand what has gone wrong. Note that being a
mechanical linkage it will be prone to becoming heavy in operation if it has
become dirty or lost lubrication.
