Customer called me with the above fridge. Looks like its an LG model. He said it had a ER DH error on the display. He unplugged it for a bit and plugged it back in and the code went away, but came back a few days later. He said he has not noticed any frost or a change in temperature.
Not sure which LG manual this is.
Looks like it has a metal heater (looked it up on sears), so I am guessing its good. I figure its a board problem, or a thermister.
Any help or suggestions on what to look for is appreciated.
