Is it worth trying to fix electrical appliances nowadays in this mass produced throw away society?

(Obviously not if you're familiar with oldskool washing machine bearings vs the new sealed tub type)

Unless you know exactly the cause of the fault and can do it yourself - probably not.

Bottom oven kept tripping out the rcd, sometimes straight away other times after a period of use, changed the element - still tripping, changed the thermostat - still tripping, wasn't worth keep throwing money at it but as a final throw of the dice disconnected the fan motor and used it conventionally - never tripped.

Ordered a new fan motor, fan is held on the shaft by a dome nut, shaft shoulder to threaded section length different on the new motor so had to cut the nut down.

Everything working fine, for now!
