Hi, welcome to Just answer
How old is it ?
also can you please elaborate the problem
light on fan oven &FANOVEN NOT FUNCTIONING
OK, how old is it ?
APROX 5 YEARS
so it is completely dead ? Does the timer even light ?
TIMER LIGHTS TOPOVEN OK
OK, and the fan wont even start
FAN NOT STARTING
OK, can you test the thermostat for the oven with a multimeter
EXPERT IS SLOWER THAN ME AT TYPING IAM ACUSTOMER NOT AN ELECTRICION
I was just checking
the problem is either the thermostat or the fan oven element itself that is bad and will need replacement
as the top oven is working fine
so it is more likely a bad fan oven element
are you looking to replace this yourself
or you want to get this done by repair engineer ?
