How to fix Kenmore F dS / r dS
Reset the power
Turn the refrigerator off at the plug or breaker for two or three minutes, then back on. Watch whether the code returns within a day.
Keep an eye on the freezer panel
Glance at the back wall of the freezer every day or two. Frost spreading across it means defrost isn't happening and cooling will fade over the coming days.
Thaw it if frost builds up
Pull the plug, transfer everything to coolers and leave the doors wide open with towels underneath until the ice is gone.
When to call a technician
The sensor sits on the coil behind the freezer panel. Sears PartsDirect says it's sold as part of a controller assembly that includes the defrost fuse, and fitting it means taking the freezer apart, so most owners leave this one to a technician.
