Thomas W Eugene , OR May 19, 2015 Appliance: Maytag Refrigerator RTC1700AAL Maytag Refrigerator Rtc1700aal / Ch26a: Refrigerator temperature knob. How to replace Knob, Control. I bought a older Maytag Refrigerator and the temperature wheel for the fridge was missing, although the original one was not longer available, I ordered the newer one from AppliancePartsPros.com and it works fine, not matching with freezer knob but who cares. Thank you, Tom 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
