W10822278 / 2188372 Refrigerator Defrost Timer

Key Features

  • Precision 10-Hour Cycle: Features a factory-calibrated mechanical motor that triggers a defrost cycle every 10 hours of compressor run-time, maintaining the ideal balance between cooling and frost prevention.
  • Fixed 21-Minute Defrost Duration: Specifically engineered to keep the defrost heater active for exactly 21 minutes, ensuring all ice is cleared from the evaporator coils without overheating the freezer compartment.
  • Heavy-Duty Internal Contacts: Built with high-conductivity metal points designed to switch the high-amperage load of the defrost heater thousands of times without pitting or sticking.
  • Manual Advance Dial: Equipped with an integrated "advance screw" that allows technicians and DIYers to manually trigger a defrost cycle for diagnostic testing without waiting for the 10-hour timer.
  • Standard 4-Pin Layout: Features a keyed electrical connector that ensures a proper, one-way fit into the refrigerator's wiring harness, preventing accidental short circuits.

Compatibility & Fitment

This defrost timer is one of the most widely used mechanical controls in Whirlpool Corporation's history. Key compatible brands include:

  • Whirlpool & Kenmore: Fits a massive range of top-mount and side-by-side models (e.g., 106-prefix and 110-prefix units).
  • KitchenAid: Compatible with many older series built-in and freestanding refrigerators.
  • Maytag: Fits various models produced following the Whirlpool-Maytag brand integration.
  • Amana, Roper, & Estate: Direct replacement for almost all mechanical-timer units in these value brands.
  • Note: This part is typically located either in the control console at the top of the refrigerator or behind the bottom kickplate (toe grille) near the compressor.

When to Replace

  • Fridge Stays Too Warm: The timer is stuck in the "cooling" mode and never triggers a defrost, leading to evaporator coils that are choked with ice.
  • Fridge Won't Start: The timer is stuck in the "defrost" mode; the lights will work, but the compressor and fans will never turn back on.
  • Compressor "Clicks" But Doesn't Run: If the internal contacts are worn, they may fail to provide enough voltage to engage the compressor's start relay.
  • Audible Clicking or Grinding: The small internal motor of the timer has failed or the plastic gears have stripped, preventing the dial from advancing.
  • Timer Won't Advance Manually: If you turn the advance screw and the fridge doesn't kick on or off as expected, the internal mechanical bridge is likely broken.

Installation Tips

  • Safety First: CRITICAL: Unplug the refrigerator before starting. Even though this part is small, it controls the main power to the compressor and heater.
  • The "Screw" Test: PRO TIP: Before replacing, use a flat-head screwdriver to slowly turn the advance screw clockwise until you hear a loud "click." If the compressor turns off and the heater turns on, your timer might still be good (check the defrost heater instead).
  • Orientation Matters: While the plug is keyed, take note of how the timer is mounted. Reversing the mounting position can sometimes make it difficult to access the advance screw through the console's access hole later.
  • Check the Bi-Metal: If you replace the timer and the ice buildup returns in a week, your defrost bi-metal thermostat is likely the culprit, as it acts as a secondary safety for the timer.
  • Wait for the Cycle: After installing the new W10822278, it may take up to 10 hours for the first automatic defrost cycle to occur. This is normal operation.

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
