My beer fridge shit itself easter saturday

Had a refrig. mechanic come out today to have a look.
He was here approx 8 mins (6 mins. of that, was him listening to me telling him how tragic it was not having cold beer)


He used his screw driver to reset the defrost controller (little switch at the back of the fridge)
The fridge starts working again just fine

Then he says "you better replace that controller as it's liable to give you trouble again"
I said "OK how much will that be mate?"
"It will be $253 dollars, parts & labour" he replies
Now bear in mind the controller is held in with one screw and has 3 wires clipped to it!
It would take him 2 minutes to change it over.(if that long)
I said "I'll have a think about it mate and get back to ya"
(Now that i know whats wrong i will replace it myself if it packs up again.)
Total cost of the 8 minute callout and 2 minutes with the screwdriver
=$88
I'm in the wrong game
