Hello.

We are working on a Samsung fridge with dual evaporators/dual cooling. Model number RS267TDPN.

The freezer is ok at 0 degrees. However, the fridge compartment is at 60-67 degrees.

We get error codes E 22 and E25.

we tested the defrost heater in the fridge, and the reading was good at 102 Ohms.Specs say it should be 103 Ohms.

We tested the fridge sensor via the control board on the back (black to grey cable at CN 40)  the voltage reading was 1.89Volts, which corresponded to 68 degrees Fahrenheit. So that sensor was within specs since our temp gun read the same.

However, we then tested the fridge defrost sensor and that one had 4.1 volts, corresponding to -16 degrees farenheight. There was ice on the defrost area so this looked out of spec, right?

Lastly, we tested the fridge, freezer, and co denser fans from the control board. All were ok except for the fridge evaporator fan. The fridge evap fan was getting no voltage. We are thinking of replacing the fridge defrost sensor and the fan, however, we are not sure if perhaps it is the board that isn't sending voltage to the fan. Do we have an issue with the board as well?

Please advise.
