neff oven cuts out

[suedehead1]

HB632GBS1B/63 built in single oven it heats and fan goes then it stops heating and fan stops going but display still lit,
suspect pcb but was open to any ideas

[electrofix]

most ovens have a cooling fan. not the fan inside the oven it blows cold air around the inside and out over the door to keep things cool. if the fan fails then oven will do exactly what your is
if you remember when the oven is working correctly the cooling fan carries on running for 10 mins or so after the oven is switched off

thanks Dave i never checked that , i will get another look at it.

I’ve had earth leakage element cause this

[suedehead1]

Hi again, i changed the cooling fan it made no difference, checked for earth leakage all ok.

[electrofix]

is the cooling fan running
assume you checked that

Dave

[suedehead1]

hi yes its running and continues to run after oven switched off

[electrofix]

ok did you check if the overheat stat had tripped after it cutout ?

also above, never had it myself DPDOM says he had element problems causing this so thats worth a look

And lastly you said Neff but its come up as Siemans

Dave

[suedehead1]

your correct it is siemens i will go back and check overheat stat, i thought if it cut out everything would go off

[electrofix]

on some cookers yes but others no so worth checking

pull one wire off and switch on to see if clock goes off. if yes it cant be the stat

From what your explaining its a control module fault part number 11029688 £120.33 with bosch

What about the door switch? Some ovens stop the fan and element when it thinks the door is open to save energy – I don’t know if the switch is on the mains voltage side or the low voltage side but if it is on the low voltage side then it may not take much resistance for it to think that the door is open.

well agree there
got an oven over 50 years old , simple thermostat still works ok

dont use it much and do intend to swop it when i do the kitchen

its that old that the knob operates a bevel gear to turn the horizontal rotation to vertical rotation and a rod goes down to a rod stat. Was reconditioned when my dad bought it in 1970

thats when Belling cookers lasted lol

back out to the oven, once it gets hot there is an earth leakage at the fan oven element, going to change it and keep fingers crossed.
tried disconnecting safety thermostat and the oven still worked no heat, bypassed door lock it still cuts out,
nightmare job.
