Re: Kenwood CKJ280 fan assisted oven problems.
Update for reference.
Disconnected the power supply and removed connections to the new element, on re-connecting power supply and switching on oven the fan worked OK on it’s own without the element.
Disconnected the power supply again, restored connections to the element, re-connected power supply, switched on the oven and the fan and element both working fine!.
I’ve no idea why it suddenly stared working, only thing I can think is that on the element there is an earth connection and the other 2 connections each had 2 spades. I re-connected using the spades that were previously redundant.
