Frequently Asked Questions
•How do I test the defrost heater for continuity?
Unplug the refrigerator. Locate the defrost heater (usually near the evaporator coils). Disconnect the wires to the heater. Set your multimeter to the ohms setting. Place the probes on each terminal of the heater. A reading between 20-40 ohms typically indicates a good heater. An open circuit (OL) means the heater is faulty.
•Where is the air damper located, and how do I know if it's working?
The air damper is typically located in the upper part of the refrigerator section, often near the top vent. To check its function, observe it while adjusting the refrigerator temperature settings. You should see the damper open and close. If it's stuck or doesn't move, it likely needs replacement.
•What type of refrigerant does my Roper refrigerator use, and what are the risks of a refrigerant leak?
Most modern Roper refrigerators use R-134a refrigerant. Refrigerant leaks are best left to professionals because releasing refrigerant into the atmosphere is illegal and harmful to the environment. Refrigerant leaks also make the refrigerator less efficient and can eventually lead to compressor failure. Symptoms of a refrigerant leak can be a hissing sound, oily residue, and a lack of cooling.
