    Hi,
    its a built under double oven with a digital clock and a seperate digital thermostat.
    when the bottom oven is set to say 220 degrees it heats up then before it gets to temperature the display clicks and goes down to 160 degrees anyone had this before.
    checked all joints on pcb nothing obvious.

    Dragging up an old post here but have had two of these recentlty doing exactly the same thing. 1st customer didn’t want any repairs carried out as over 10 years old but the one today does. HB550550b/02, works for a minute or two at set temperature then clicks and resets to default 160 degrees. No obvious signs on pcb’s, anyone had this fault and is there an obvious cure?
