Common Questions & Technical Insights

Is the bulb orientation critical for the Robertshaw 5300-185?
Yes, for optimal sensitivity, the 11-5/8" bulb should be securely mounted in the path of airflow or attached directly to the heat source using OEM-approved clips to ensure accurate temperature feedback.

Can I use this for gas-fired equipment?
No, this is an electric thermostat designed for breaking electrical circuits. It is not compatible with gas valve actuation systems.

Does this unit come with the dial?
This SKU typically includes the thermostat body and capillary. Depending on the specific application, you may need to reuse the existing knob or source a Robertshaw replacement dial compatible with the flat-down shaft position.
