Rheem-Ruud SP11698 Thermostat

The Rheem-Ruud SP11698 Thermostat is a field-proven, OEM upper limit control designed for non-simultaneous residential electric water heaters. Featuring a 90°F to 150°F adjustable temperature range, this T-O-D style (Therm-O-Disc) component integrates a manual reset high limit set at 170°F to prevent over-temperature conditions. As a two-pole (DPST) high limit with SPDT thermostat contacts, it reliably manages the sequencing of heating elements, ensuring only one element draws power at a time for electrical load efficiency. Built with a temperature-sensitive bimetal disc, the SP11698 ensures snap-action contact separation, which reduces arching and extends the life of the heating element. This genuine Rheem Protech part is compatible with 208V, 240V, 277V, and 480V systems and serves as a direct cross-reference for Apcom-style thermostats used by Ruud, Richmond, and many other leading manufacturers.

Is the SP11698 compatible with other brands?
Yes, this is a standard T-O-D style thermostat that fits most residential brands including GE, State, Bradford White, and A.O. Smith, provided the system uses a non-simultaneous two-element design.

How do I know if I need to replace the upper thermostat or the lower one?
If the water is completely cold, the upper thermostat (SP11698) is usually the culprit as it controls the power feed to both elements. Verify the manual reset button hasn't tripped before replacing.

Does this part include the high-limit switch?
Yes, the SP11698 is a combined upper thermostat and high-limit control unit in a single assembly.
