WATER SENSOR ASSEMBL

Water Sensor Assembl (PN 02-4449-21) supports ice machine service when wear, damage, or fitment issues are disrupting normal operation. Sensors and probes feed signals that influence timing and safety decisions. Incorrect readings can cause short cycling, nuisance shutoffs, or inconsistent output. If the machine is showing timing errors, inspect this area for looseness, rubbing marks, mineral buildup, or secondary damage to nearby parts. A solid approach is to confirm the symptom, then check mounting points and adjacent connections for contributing issues. Use part number 02-4449-21 as the primary identifier, compare the replacement to the original, and install with careful alignment and routing. Once the root cause is corrected, performance should stabilize and output should return to normal. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly.

Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. If the part interacts with water, do a leak check during the first run and again after a short operating period.
