Sean for Model Number RS2534vq I purchased a new freezer evap motor after my freezer's temperature started to rise and I confirmed the old motor was not working. After installation the temperature dropped to 1 degree, though it took about 6 hours to do so. After that, it started to rise again and is holding steady at 32 for the past few days. I took the cover off and tested the new fan to verify it is still working. The coils have ice on the bottom of them, could this be the reason the temp has started to rise again? If so, would taking a hair dry to it be a workable solution or would it lead to other issues? A picture of the coils can be seen here: https://www.betterourtomorrow.com/freezer/freezer_pic.jpg . Any help is appreciated.
Answer Hi Sean. Yes if you have abnormal frost on the coils it block proper air flow and decreases cavity temperatures drastically. A typical no cool. This involves testing and replacing the defrost thermostat part # DA47-10160H which should naturally read closed (0-ohms) in frozen temperatures. Check at the board terminals Freezer Def Heater between CN70 (13) and CN70(7) .The heater part # DA59-00233H has 2,600 ohms resistance and not open. The evaporator thermistor part # DA32-10105R has at room temperature of 77.0° and 1.667 volts dc, w/5.000 ohms. At 32° you need 13.290 ohms, at 2.853vdc. If this is out of value by 5% it needs replaced as well. You need to make sure the defrost thermostat receives 120 vac when the control board part DA41-00134F defrost cycle in time. Thank You.
