I have a Breville 'smart toaster oven' which I've used for 7 years in two different apartments with no problems. As of the last month, the toaster oven will randomly trip the circuit (that is, in the kitchen wall outlet, which can be reset by clicking in the button in the outlet itself; does not trip the fuse in the house-wide breaker, apologies if incorrect terminology). I tried multiple outlets, same issue. Sometimes it happens after 2 seconds, sometimes after 1 minute.
Does anyone have any advice here? It is definitely out of warranty, and I know that parts+labor from a professional shop will be more than a new one (I called a couple) so.. can I do any kind of repair myself that wouldn't be too tough, or is it just time to give in and buy a new one? I hate to buy new when I can fix so would appreciate any leads, especially if it wouldn't be too expensive. Thank you in advance.
EDIT: Based on answeres here I have realized the outlet is GFCI. I just tried plugging the toaster into a non GFCI outlet, it works! Is this: A) OK for short term as I order/research a new toaster and B) possibly OK for the long term rather than replacing a toaster?
