By accident, I shorted the dispenser switch wire harness on my Superba KSSP48QHS00. Now I have frost all over the freezer side and heat on the fridge side. What is it that was damaged: the bi-metal ? the defrost timer ? the defrost control board ? Where are they located on this model ?

Thank you,

The bi-metal(defrost thermostat) is located inside the freezer on the top of the evaporator coil, its #1 here:

The defrost timer is #30 here, its up above your refrigerator:

I'd first turn the timer into defrost mode, use a flathead screwdriver, you should see a small hole in front so you can turn it, turn it slowly till the refrigerator turns off, then after a few minutes notice if your defrost heater is on, the defrost heater is #17 in the first diagram.

I changed the bi-metal and the refrigerator is working fine now. Thanks.

Now the low pressure coper tubing on top of the fridge is frozen. Why? What is next?

Good job replacing the bi-metal.:)

You mean the low pressure side is frosted up back to your compressor?

Ok, thats very odd, because that only happens when too much freon is in the sealed system, and since no one has opened the sealed system, thats a mystery to me.

Only way to stop that is to open the sealed system and remove/recover some freon, but that requires a licensed refrigeration tech. to do that.

No, it shouldn't effect the cooling. Yes, you can leave it like that if you want, if it starts effecting the cooling, then you will need a licensed refrigerator tech. to come out.

Hi Jake!

A few weeks have gone by and the low pressure side is no longer frosted.

Do that signal a leak?

Not necessarily, if you start to notice a cooling temp. loss, then yes. But if its still cooling properly you should be fine.
