Guys,
I have a fault with a 6kW Nightstore heater.
Usually I can sort a fault like this out for myself.
But, I have replaced the second set of Elements in this particular unit and it just keeps blowing elements, one after the other.
The customer is getting really annoyed with the repeat calls (out of warranty, too!)
What do you reckon is wrong here?.
Any advice would be most welcome!. [Linked Image]
