Common Questions

How do I confirm if this thermostat is compatible with my appliance?
Verify the 5300 series application and check your original part for the K-40-36 or Robertshaw 5300-073 stamp. This model is a direct acting control with a 1/4" nickel bulb; ensure your existing mount accommodates these dimensions.

Can this be used for both commercial fryers and ovens?
Yes, as long as the 100-550°F range and 25A rating meet the appliance specifications. It is commonly utilized across various industrial heating systems requiring an open-high configuration.

Is the dial included with this part?
This specific model generally matches with a 4-way Slip-Fit dial (1-10 scale), though we recommend verifying if your existing knob matches the 13/16" stem length or if a new dial kit is required for your specific faceplate.
