I agree with both of you in many ways, I don't understand why the need for an evaporator being replaced, and as Bryan stated, probably inexperience on the techs part (lack of proper info and/or training).
The first I heard of moving the thermistor to the center was from the ASTI notes.
Here's my notes from Evernote on this challenge. As a side note here's a few other Samsung tips I've learned recently.
I haven't looked at the wiring diagram for this unit yet but, most likely 120v goes to the heater though the Power switch and the Control supply the other 120v. So with a shorted element the element would heat at a lower heat output because the ground would be providing a neutral path.
The kit is for him or her to buy a Gladiator I only know of Frigidaire having any kind of kit like that.
The only reason that Frigidaire has a kit, for both a hot and cold garage, is because they sell such cheap x-top units that everyone thinks they can use it for a garage refrigerator. They still don't guarantee the unit if it's installed in a garage and the kits are only sold as accessories.
What do you mean it looks like it's getting full voltage, unless there's some magic method to sing voltage, then the only way is to put a meter on it and check. Either it's not getting full voltage or the element is becoming weak.
