Hope I've got the right section of the forum for this question (please redirect me if not).
I'm looking at a Horstmann Economy 7 timeswitch which appears to need replacing.
However the timer (24 section is still turning) and the boost timer winds itself down properly, so the timer parts of it are still working fine - but neither of them trigger the orange lights to come on or the immersion to start actually doing it's job of heating water.
Before I replace the box I wanted to be sure that it is the timerswitch which needs replacing and
that I'm not going to replace it and then find that I need to replace the element in the immersion
(again - it was replaced about 2-3 years ago) or the thermostat (currently set to 50).
Extra background info in case it's useful:
It's an old system in an ex-council house which used to share the immersion tank with a back boiler system (long since mostly disconnected from the actual back boiler - a plumber has removed connecting pipes so that shouldn't be interfering). For the last few years it's tripped it's main fuse box switch every few nights (almost as if the fuse is acting as a thermostat trip) but it's still working fine so long as the trip is reset.
I'm about 85% sure that it is the timer switch and that the switches in it have probably just burnt out,
I'm just after reassurance that if the thermostat or element were dead then the timerswitch would still have it's orange light on and be trying to heat and so the current symptoms are definitely a dead Timerswitch.
Also any recommendations of the best source for really cheap second hand Hortsmann Economy 7 Quartz welcome..
Thanks
