Robertshaw Electric Thermostat Replaces KX-87 299

SKU CH-FKME-DATSF

A learning electric thermostat with a 36 in capillary tube replaces KX-87 299 for commercial cooking equipment

  • TypeLearning Thermostats
  • Direct replacement for KX-87 299 models
  • 36-inch capillary tube reaches distant sensing points
  • 3/8-inch bulb diameter fits standard mounting
  • 7/8-inch stem length suits common installations
  • Compatible with major commercial kitchen brands

Direct Replacement for KX-87 Models

This Robertshaw electric thermostat is designed as a direct replacement for part number KX-87 299. It serves commercial kitchen operators and HVAC technicians who need a reliable temperature control for compatible cooking equipment. The learning thermostat function adapts to usage patterns for consistent performance.

Fits Existing Capillary and Bulb Dimensions

The control uses a 36 in capillary tube with a 3/8 in diameter sensing bulb that is 5 5/8 in long and a 7/8 in stem length. These measurements allow it to mount into the same openings used by the original control on listed brands such as American Range, Blodgett, Frymaster and Imperial. No cabinet modifications or new wiring harnesses are required for installation.

Mechanical Operation With No External Power Draw

The thermostat operates through capillary pressure changes rather than electronic sensors, so it draws no electrical power for its sensing function. This eliminates the risk of sensor drift from voltage fluctuations and produces no fan or relay noise during normal cycling. The purely mechanical design also avoids standby consumption in always-on kitchen environments.

Questions about this item

How far does the 36 in capillary tube reach inside the oven cavity?

The 36 in capillary tube extends the sensing bulb deep into the oven so the thermostat can measure temperature at the cooking zone.

How much heat does the Robertshaw 299 generate during continuous service?

As a mechanical capillary thermostat it produces no electrical heat of its own; only the oven burner or element creates heat.

Which mounting hardware must already be on the range for the 7/8 in stem to fit?

The 7/8 in stem threads into the existing control-panel cutout used by the original KX-87 thermostat.
