RT18DKXKT03 Roper Refrigerator

I troubleshot the problem by reading the electrical schematic and concluding the heating elements (defrost cables) were either defective or the bi-metal temp sensor was open. When closed the temp sensor completes the circuit for the current to flow through the heaters to defrost the cooling coils every 8 hours and then when the bimetal o ... Read more pens at 55 degrees the circuit is open and the coils are cooled because the refridgeration motor is in run mode. A timer between the motor and heater elements also was defective. The timer controls the cooling period and the defrost period. I ohmed out each part according to the spec sheet of normal resistance of parts and thus the bimetal and timer were defective. I gather a surge of some duration and amplitude affected these parts because a storm 24 hours prior to refridgerator problem had passsed through the area and the AC electrical power had oscillated several times during that event. I used hand tools to do the repair. If you are not mechanically inclined a step by step proceedure would be moot. It is a matter of disassembly and assembly paying close attention to fragile parts.

I knew the chances of all the freon leaking out was unlikely so I looked at the wiring to the compressor and there was a capacitor and a starter/overload so i figured I would start there. I went on line and found the parts at this site and they were less than the minimum service call charge for a service tech so I figured what the heck le ... Read more t's give her a shot so I did give it a shot. I ordered the parts and they were there in less time than a service tech could come out and i installed the parts and guess what for 90.00 in parts and 15 minutes in time I repaired my refrigerator. Thanks guys, It took less time to order the parts than it did to make the repair so thanks, your website rocks and is very well designed so my hat is off to you guys!

First I removed the two screws that secure the guard in bottom back of the freezer and removed it . Next I removed the two screws that secure the guard on the back wall of the freezer and removed it. There are three wires connected to the motor, I unplugged those and removed the two screws that secure the motor and removed it. I swapped t ...

I saved her at least $400 to buy a new fridge. Thank You, Brian Miner
