Our reach in 1 door freezer has an error code of HA listed. It does this every couple of days. Last week, we emptied it out, defrosted it and then brought it back on and it was fine. Now the code is coming back on. Essentially it flashes for a day or so and then begins to lose temp. Ideas on a fix or an override?
