The customer reports he is having to manually defrost this unit every 3-4 days. He states that another servicer has replaced the control board & "something inside the freezer compartment" but the unit still does not defrost. I cannot locate a termination thermostat on the drawing. I am assuming that the unit goes into defrost, but cuts out early. Do you have a part number for the thermostat or whatever part it is that terminates defrost? The customer already has $500 in this repair with no results and the original servicer says there's nothing he can do.

Do you have access to the tech sheet to run diagnostics to check the thermistors and heater in the freezer. The thermal fuses may be blown that are in line with the heater. Looks like the evaporator thermistor controls the defrost. There is an evaporator thermistor and a freezer thermistor in the freezer compartment.

These are the only thing I've found wrong with this model type when it comes to defrost issues. I'd be willing to bet it was changed already if they said something in the freezer was changed.

I'll take that bet. I bet the servicer changed the defrost limit....

If he changed the board but the problem was just a thermistor, that tells me the previous tech probably didn't know what he was doing.
I bet he was using old diagnostic methods on a machine with newer technology... ie he checked heater and limit... they probably checked out ok, so that leaves the board.... so he changed the board and then changed the limit for good measure. Probably wasn't aware of a thermistor.
So Bro Bryan, get your money ready as I have faith in and am banking on the current sad state of appliance techs. Why not? I witness or read about it on a daily basis.

Thanks for all the help. I have ordered the thermister. I doubt that any part was changed in the freezer after talking to the customer again. His receipt only showed the control board and he remembers the tech telling him he would change out another part if he had it on his truck. What kills me is the company won't stand behind their work. If I were this guy, they would fix it or refund my money. I don't know if they even did a diagnostic check. The customer swears the guy came in, defrosted the freezer, called someone and then told them they needed a new control board. He came back a week later, pulled the unit out, changed the control board, told the customer to leave it unplugged for a couple of hours and left. Since then, the servicer has told them that the problem is in the sealed system and beyond economical repair and since he can't return the control board, there's nothing they can do. The unit operates great for 4-5 days after it is defrosted so they are just blowing smoke. Anyway, it will be next week before I go on this call, but I will post the outcome.

so I imagine they would have one as a safety like GE uses.
Federal requirement that there be a bimetal connected to the heater so you can be certain there is one in all fridges using a defrost heater.
