Ten yr old DeLonghi Professional electric fan oven
When oven is on it does not respond to the temperature gauge – it just gets hotter and hotter until it reaches about 300C then switches off after 30mins.
I replaced the Oven Thermostat in 2008 – problem resolved issue.
I replaced the oven thermostat in 2012- problem persists Please help!!! 😐 😐
Sounds like the thermostat again but I can’t think of any reason that it should fail, especially the same way, so soon after replacement… twice. Very odd.
