    Hi
    Got a strange fault with this oven,it works fine both ovens will go up to temp perfectly.But as soon as the cooling fan switches off (after 20mins or so)It takes the trip out in the house.
    checked the oven throughout i cannot get to the bottom of it.
    any ideas pls.

    Well for a single multi-function oven this baby is a doozie. So, firstly you MUST Megger it (yes I know, granny sucking eggs and all that) but it must show pretty near on infinity otherwise with sensitive MCB’s you’ll get this. Also there is a sink resistor on the cooling circuit that could be your problem (fitted on the top adjacent the fan). What else?…..dunno….have you done a loop test?
