Electric cook control thermostat

The Robertshaw 5200 Series Learning Thermostat Z90644-36 is an electric cook control designed for commercial kitchen equipment. It replaces OEM part numbers including 23136, E-183, F16-897 and Z90644-36. The unit operates on 120V AC or 240V AC input voltage and fits Consolidated Communications, Johnstone Supply, Robertshaw and Uni-Line branded appliances.

Replaces Z90644-36 and compatible OEM parts

This thermostat serves as a direct replacement for the Z90644-36 and cross-referenced OEM numbers across the 5200 Series. The jump is worthwhile when the original control fails to hold temperature or the capillary tube is damaged. It restores factory calibration without requiring wiring changes on supported equipment.

Sustained temperature regulation up to 210°F

The sensing bulb measures 15 3/8 in length with a 1/4 in diameter and connects via a 36 in capillary tube to a 1 in stem. It maintains a control range from 60 to 210 degrees F during continuous heating cycles. The bulb responds to gradual temperature drift in ovens and holding cabinets rather than short bursts.
