How can I fix my Dimplex XL5N storage heater?
My Dimplex XL5N storage heater keeps blasting out heat with no apparent control, even when the output control knob is turned right back. There's what looks like a thermocouple at the right back of the heater which is just dangling. Could this be the problem and if so how do I fix it?
