Description
The Bakers Pride AS-S1453A (also listed as BKPAS-S1453A / BKPS1453A / BKPS1453X) is a genuine OEM replacement knob for the gas valve (Robertshaw 700-Series) on many commercial ovens. It’s used to switch settings like Off / Pilot / On on the common gas valve used in this family. If the original knob is broken, missing, or stiff, replacing with a correct fitting knob restores full control over safety pilot and burner functions.

💡 Tech Tip:
-
When fitting, make sure the D-shaft alignment matches; the flat side on the stem must align with the flat in the knob hole, so that “Off / Pilot / On” markings align correctly.
-
Check that the knob isn’t rubbing or too loose — if loose, gas valve control can slip or not sit securely in pilot position.
-
For replacement in ovens, clean the shaft and valve face so the knob slides on smoothly. A little dab of high-temp grease on plastic contact surfaces can help avoid sticking.
📌 Note:
-
Although the knob is a small component, because it’s directly attached to the gas valve control, it’s part of the safety chain. A knob that’s broken, partially missing or doesn’t securely set to “Off” or “Pilot” is a hazard.
-
Always confirm your valve is indeed a Robertshaw 700 Series or compatible type; there are valves that look similar but have different shafts or knob fittings.
-
OEM cross-reference part numbers are useful for sourcing; the AS-S1453A is now the current version.
