HI - engineer arrived promptly to fix faulty oven , replaced fan and elemnt .unfortunately it only worked breifly before fault reoccurred . he reattended (again pronmptly ) and did some rewiring. again only worked breifly before same fault. reattended id some more rewiring but fault reoccurred yet agin Declined to re visit opining that we needed new oven so although prompt in visiting/revisiting problem was not fixed despite some cost involved (2 parts plus visit fee) so a bit disappointing outcome . would obviously have ben preferable to "condemn " oven on first viist .
