What Our Customers Say
"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

"Wonderful and top notched care! They were able to meet my same day expectation to get a washer and dryer hooked up in a new house. He was attentive, thoughtful and explained it all as well. I would highly recommend their service!"

What Error Code Er IT Means
The Er IT code means the ice maker motor cannot complete its harvest cycle. The motor rotates the ice tray or ejector arms to dump ice into the bucket. If the motor stalls, the tray jams, or the ejector arms cannot rotate, the board detects the failure and displays Er IT. Ice production stops until the jam is cleared or the motor is replaced.
Common Causes
Frozen ice tray or ejector arms
Water overflows the ice mold during a fill cycle, freezes around the tray and ejector mechanism, and locks everything in place. The motor cannot generate enough torque to break through the ice.
Failed ice maker motor
The gear motor that drives the tray or ejector arms burns out. You hear a humming or clicking sound during the harvest cycle, but the mechanism does not move.
Broken ejector arm or tray
A cracked plastic tray or bent ejector arm physically cannot rotate. The motor runs but the mechanism jams.
Ice cubes jammed between tray and housing
Irregular or oversized ice cubes wedge between the tray and the ice maker housing. The motor stalls trying to push past the obstruction.
How to Fix It
- 1
Remove the ice bucket and check for jammed ice
Pull the ice bucket straight out of the freezer. Look into the ice maker compartment for ice cubes wedged between the ejector arms and the housing. Remove any stuck cubes by hand. Replace the bucket and see if the ice maker resumes its cycle.
- 2
Thaw ice around the tray
If the tray or ejector mechanism is encased in ice, unplug the refrigerator. Use a hair dryer on low heat to melt the ice around the tray, keeping the dryer 6 inches from plastic parts. Once everything moves freely, restore power and test.
Unplug the unit before using a hair dryer inside the freezer compartment.
- 3
Manually cycle the ice maker
Most LG ice makers have a test button on the ice maker assembly. Press and hold it for 3 seconds. The ice maker should run through a complete test cycle: the tray rotates, ice ejects, and the water valve opens to refill. If the motor hums but the tray does not rotate, the motor or tray is the problem.
- 4
Inspect the tray and ejector arms
Remove the ice maker assembly from the freezer (usually 2-3 Phillips screws and a wire harness connector). Examine the plastic tray for cracks. Check the ejector arms for bends or breaks. Cracked or deformed parts need full ice maker assembly replacement.
- 5
Test the ice maker motor
With the ice maker assembly removed, disconnect the motor harness. Set a multimeter to the 2K-ohm range. Measure resistance across the motor terminals. Expect 500-2000 ohms depending on the model. OL means the motor winding is open. Replace the ice maker assembly.
Confirm the unit is unplugged before testing motor resistance.
When to Call a Professional
If jammed ice is not the cause and the motor or tray is physically damaged, the entire ice maker assembly needs replacement. A technician ensures the water fill volume is calibrated correctly to prevent future overfill and freeze-ups. TruePro's $59 diagnostic is credited toward the repair.
