The water supply line connecting your Jenn-Air ice maker to the household plumbing should be inspected regularly for signs of wear, corrosion, or potential failure. A burst supply line can cause significant water damage, especially for under-counter installations where leaks may go unnoticed.
Affected Models
All Jenn-Air under-counter ice makers, freestanding ice makers, and any Jenn-Air refrigerator with a connected ice maker or water dispenser.
What to Inspect
- Check the supply line for kinks, bulging, or cracking
- Look for mineral deposits or corrosion at connection points
- Verify the shut-off valve operates smoothly — turn it off and on to confirm
- Check for moisture or water stains under and behind the unit
- If using a copper supply line, inspect for green corrosion (verdigris)
Supply Line Recommendations
Replace copper supply lines with braided stainless steel lines — they are more durable and resistant to kinking and corrosion. Replace any supply line that is more than 10 years old regardless of condition. Braided stainless steel ice maker supply lines cost from $15 and are available at any hardware store.
Urgency Level
Moderate — inspect during regular maintenance. Immediate if any moisture is detected near supply connections. A burst supply line can cause thousands of dollars in water damage.
