David Chen Key Takeaways
- Er 15 on a Kenmore refrigerator points to an ice maker temperature sensor problem
- The fix is usually replacing the ice maker assembly or the sensor itself
- DIY replacement costs from $50-150 for parts, professional service runs higher
- This error stops ice production until the sensor is working again
The Bottom Line
The Er 15 error on your Kenmore refrigerator means the ice maker's temperature sensor has failed or lost contact. You can replace the ice maker assembly yourself for around $50-150, or call a pro if you're not comfortable with the work.
What Er 15 Actually Means on Your Kenmore
Er 15 (sometimes shown as Er IS) is an ice maker sensor error. The ice maker has a temperature sensor that tells the control board when the ice tray is cold enough to release the cubes. When that sensor fails or loses its connection, the fridge displays Er 15 and stops making ice.
Kenmore doesn't make its own appliances. Your refrigerator was built by an OEM like Whirlpool, LG, or Frigidaire. The error codes are similar across brands, but the fix might vary slightly depending on who made your unit. Check your model number prefix to know who built your fridge.
How to Diagnose the Er 15 Error
Before you order parts, confirm the error is really Er 15 and not something else.
- Press and hold the refrigerator temperature button and the freezer button at the same time for 3 seconds
- Watch the display for error codes cycling through
- Er 15 or Er IS means the ice maker sensor has an issue
- If you see other codes, address those first
The ice maker will stop producing ice when this error is active. That's the most obvious sign something is wrong with the sensor circuit.
What's Actually Failing
Three things usually cause Er 15 on Kenmore refrigerators:
- Failed ice maker temperature sensor: The thermistor inside the ice maker has stopped working. This is the most common cause.
- Loose wiring harness: The connection between the ice maker and the control board has come loose or corroded.
- Faulty ice maker assembly: The entire ice maker unit has failed and needs replacement.
Your Repair Options
Option 1: Replace Just the Sensor
Some models let you replace just the temperature sensor (thermistor) inside the ice maker. This is cheaper if your model supports it. The sensor itself is usually under $30.
Check your service manual or search by model number to see if the sensor is a separate part on your unit. Not all Kenmore ice makers have replaceable sensors. Some are built into the ice maker mold assembly.
Option 2: Replace the Ice Maker Assembly
This is the most common fix. You replace the whole ice maker unit. Parts run from about $50 for generic replacements up to $150 for OEM parts from Whirlpool or LG.
The job takes about 30-45 minutes if you're comfortable working inside the freezer. You'll need to:
- Disconnect power to the refrigerator
- Remove the ice maker assembly from the freezer
- Transfer the harness and fill tube
- Install the new assembly
- Test ice production
Option 3: Call a Professional
If you're not comfortable doing the work yourself, call a repair technician. Labor for ice maker replacement is typically from $100-200 depending on your area. Total bill with parts and labor is usually from $150-350.
What You're Looking at Spending
| Repair Option | Parts Cost | Total with Labor |
|---|---|---|
| DIY sensor only | Under $30 | Under $30 |
| DIY ice maker assembly | $50-150 | $50-150 |
| Professional service | $50-150 | $150-350 |
These are rough ranges. Your exact cost depends on your model and where you buy parts. OEM parts cost more than aftermarket, but they fit better and last longer.
What to Order
You'll need your full model number to find the right ice maker. Kenmore model numbers are on a sticker inside the refrigerator, usually on the wall near one of the door frames.
Look for the ice maker part number in your service manual, or search for "ice maker assembly" plus your model number on parts sites. Generic replacements exist for many models, but verify the part number matches your original before ordering.
What Happens After the Fix
Once the new ice maker or sensor is installed and the error clears, your refrigerator should resume normal ice production. Give it 24-48 hours to get back to full ice output after a new installation.
The Er 15 code should disappear from the display immediately when you restore power with the new part installed. If the code comes back, you may have a wiring issue or a bad control board.
When to Just Replace the Fridge Instead
If your refrigerator is over 10 years old and has other issues, a new ice maker might not be worth the investment. But for a unit under 8 years old with no other problems, fixing the Er 15 error is the right call. The repair cost is a small fraction of replacement.
New refrigerators run from $800 to over $2,000 depending on features. Fixing the ice maker is almost always the cheaper option unless your fridge is already on its last legs.
Keeping the Ice Maker Running
Ice maker failures happen. You can't prevent a sensor from eventually failing. But you can extend the life of your ice maker with basic maintenance:
- Replace the water filter every 6 months
- Clean the ice bin periodically
- Check the fill tube for ice buildup in hard water areas
- Keep the freezer at 0 degrees Fahrenheit or below
None of this prevents sensor failure, but it reduces other ice maker problems that could compound the issue.
Where to Get Parts
OEM parts for Kenmore refrigerators come from the manufacturer that built your unit. Check the Kenmore support site for your model, or look up parts by the OEM part number if you know who made your fridge.
Aftermarket ice maker assemblies are cheaper and work well in most cases. Just verify the part number matches your original before ordering. Installing the wrong ice maker won't fix the Er 15 error.
