Water Pooling Under Your Fridge or Frost Buildup? A Failed Defrost Heater Pan WPW10281063 Is the Cause – Fix It Fast

When your refrigerator starts leaking water onto the floor or you notice excessive frost accumulation in the freezer compartment, the defrost heater pan is one of the first components to suspect. In most KitchenAid, Jenn-Air, and Dacor built-in refrigerators, a cracked or failed heater pan allows defrost water to escape the drain system entirely. When it fails, water bypasses the evaporation tray and pools beneath the unit — damaging flooring and creating a slip hazard. ⚡ Don't wait — water damage compounds fast. Part WPW10281063 is the genuine OEM replacement that restores proper defrost drainage and eliminates leaks permanently.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Your refrigerator is a KitchenAid, Jenn-Air, Dacor, or Thermador built-in model
• ✔ Water is pooling under or around the base of the refrigerator
• ✔ The freezer is defrosting on schedule but water isn't evaporating
• ✔ You've confirmed the drain tube is clear and not blocked
• ✔ ONLY problem is defrost water leaking or pan cracked/damaged

🔧 Common Symptoms

• Water puddles forming under or in front of the refrigerator
• Visible cracks or warping on the existing defrost pan
• Frost buildup in freezer despite normal defrost cycle operation
• Musty odour from standing water beneath the unit
• Water stains on flooring around the refrigerator base
• Defrost water not evaporating — pan overflowing during defrost cycle

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this heater pan restores normal operation immediately.

⚙️ Installation Notes

Skill Level: Moderate — 30–45 minutes. Unplug the refrigerator and pull it away from the wall before beginning. The pan is typically accessed from the rear or underside of the unit — consult your model's service manual for exact routing. Slide the old pan out, transfer any wiring connections if applicable, and seat the new pan firmly before pushing the unit back into position. Do not overtighten any mounting clips — the pan is plastic and can crack under excess force.
