Frequently Asked Questions
•How do I test the defrost heater with a multimeter?
Set your multimeter to the ohms setting. Disconnect one wire from the defrost heater. Place the multimeter probes on each terminal of the heater. A reading between 20-50 ohms generally indicates a good heater. An open reading indicates a faulty heater.
•Where is the defrost timer located on my Roper refrigerator?
On older models, the defrost timer is usually located behind the kickplate at the bottom front of the refrigerator, or sometimes behind the control panel inside the refrigerator section. Newer models use an electronic control board instead of a mechanical timer.
•How often should the defrost cycle occur?
Typically, the defrost cycle occurs every 6 to 12 hours, lasting for about 20-30 minutes. However, some newer refrigerators use adaptive defrost, which adjusts the frequency based on usage patterns.
