Honeywell 230163 Upper Water Heater Thermostat Hlc-apcom

Product Description

The HONEYWELL 230163 is an upper thermostat designed for residential electric water heaters. It controls the upper heating element by sensing water temperature and cycling power to maintain the setpoint. This part follows the HLC-APCOM mounting style, making it a direct-fit replacement for compatible tank-style water heaters. Licensed plumbers and water heater service technicians are the primary installers. The thermostat is a critical safety and control component — it works in tandem with the lower thermostat and high-limit cutoff to protect the tank and deliver consistent hot water output.

The 230163 is suited for residential electric storage-type water heaters where an HLC-APCOM style upper thermostat is specified. It is noted to fit AO Smith, State, and Lochinvar water heater models that use this thermostat form factor. This part is typically found in single-element and dual-element tank configurations where the upper thermostat governs priority heating at the top of the tank.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Always disconnect electrical power to the water heater at the breaker before removing the access panel or handling any thermostat components. The thermostat mounts against the tank wall and must make full contact with the tank surface for accurate temperature sensing. Follow local plumbing and electrical codes, including applicable NEC requirements for water heater wiring.
