Suburban IW60 / Nautilus Water Heater White Digital Control Center 162252

The Suburban 162252 White Digital Control Center is an OEM wall-mounted controller used with select Suburban IW60 / Nautilus tankless RV water heaters.

Important Fitment Information

Suburban used multiple control-center designs across its tankless water heater product lines.

• If your existing controller is marked 161252 or 162252, this is the correct replacement family.

• Later parts catalogs may reference 162291 as the replacement for this controller.

• Do not order this controller for an ST42 or ST60 based on appearance alone. Those models use a different control-center design, including Suburban 233678.

Potential Issues

Before replacing the control center, inspect the 12V power supply, wiring harness, connectors, ground connections, and water heater control board. A blank or unresponsive display can be caused by a wiring or power problem rather than a failed controller.

Also inspect the communication wiring between the wall-mounted control center and the water heater for loose connections, corrosion, or damaged wires.
