Manitowoc IYT0500A Parts — Indigo NXT Ice Machine

The Manitowoc IYT0500A is a current-generation Indigo NXT half-dice ice machine producing ~500 lbs of ice per 24 hours. Popular in restaurants, hotels, and c-stores across the US. The Indigo NXT platform uses AlphaSan antimicrobial protection, ice thickness sensor calibration, and refined water valve design over older Manitowoc generations. ChefParts stocks OEM Manitowoc IYT0500A parts.

Common IYT0500A Replacement Parts

• Water inlet solenoid valve — controls water fill; common failure point.
• Ice thickness sensor (probe) — controls harvest cycle timing; miscalibration causes thick or thin ice.
• Water pump (evaporator recirculation) — keeps water flowing over the evaporator during freeze cycle.
• Condenser fan motor (air-cooled units) — front-mounted; failure causes high-pressure lockout.
• Purge water valve — empties sump between cycles; scale buildup jams it.
• Curtain switch — detects when ice bin is full; failure causes over-run or premature shutoff.
• Bin thermostat — senses bin temperature to trigger next cycle.
• Water filter cartridge (Manitowoc K-00464) — replace every 6 months in hard-water markets.
• Cleaning + sanitizing chemicals (Manitowoc IIC-9 cleaner + IIS-11 sanitizer) — quarterly cleaning is required per warranty.

IYT0500A Common Failure Modes

Not making ice: water supply first, then water inlet valve, then scale on evaporator (clean cycle), then refrigerant (call HVAC tech).

Thin or thick ice: ice thickness sensor calibration — adjust or replace.

Ice tastes bad or looks cloudy: water filter overdue OR scale in sump — clean cycle + filter change.

Machine shuts down mid-cycle: high-pressure lockout — clean condenser coil first.

Machine won't harvest: hot gas valve or harvest solenoid failure.

IYT0500A vs IYT0450A / IYT0620A

Different production capacities in the same Indigo NXT family. Many parts (control boards, sensors, valves) are shared across the range, but evaporator and condenser components differ. Verify by IYT model number and serial.

Family Members

IYT0450A (450 lb/day), IYT0620A (620 lb/day), IYT0900A (900 lb/day), IYT0500W (water-cooled variant). Older S-Series (SD0322A, SD0422A) use different parts entirely.
