Robert B for Model Number RS267LASH/XAA I need to order the evaporator assembly AP4171999. I read a customer response about the part leading me to believe that I won't have to solder or worry about freon escaping It follows: Bad defrost heater and sensor (display showing code 3 at startup) Kenneth P. • Centerville, GA • September 22, 2014 Appliance: Samsung Samsung Refrigeration RS2578BB/XAA My Repair & Advice Purchased new evaporator/heater/sensor assembly from appliance parts. Removed new heater, sensor and wire harness from new assembly and from existing unit in refrig section. Then installed new heater and sensor on old refrig evaporator, avoiding complex soldering and recharge with Freon. Once repaired all failure indications cleared and refrigerator section performing like new. Also purchased new heater for water tank and several broken plastic parts that went in in 2 minutes. Changed door light switch which had become intermittent.

Which is correct? All service sites that I have contacted are a week out on any service calls! Also, I measured the resistance of my drain heater and it measure 4300 ohms, Part number AP4137756. Is that OK? Sounds a little high as it would yield about 3.5 Watts. Please advise soon so that I can possibly fix this myself. I am vey technical but don't have HVAC tools. - Thank you!
Answer Robert, It is possible to replace the heater on the evaporator without having to replace the entire evaporator. You would have to order the evaporator assembly. Once you receive you will need to remove the heater part of it off the old evaporator and install the new heater part off the new evaporator. This will take time and patience as you have to bend the tabs that hold the heater to the evaporator. As for the drain heater, the resistance of 4300 ohms would be higher than normal and you would want to replace this also. Read More... Answered by AppliancePartsPros.com | Thursday, October 30, 2014
