Potterton Upper Casing Support Right 5139908

The Potterton 5139908 is the right-hand upper casing support for Potterton Commercial NXR4i boilers. It forms part of the casing assembly and holds the upper casing panel in position on the right-hand side of the appliance. It is a Potterton Commercial spare, listed under casing components for gas boiler spares.

• The casing panel no longer sits square or flush on the right-hand side.
• Visible distortion, cracking or bending of the support.
• Corrosion or surface degradation on the support where it contacts the casing.
• The upper casing panel is loose or rattles because the support no longer holds it correctly.
• The support has been damaged during servicing or panel removal.

• Confirm the appliance is a Potterton Commercial NXR4i and note the section count of the boiler.
• Check whether the left-hand or right-hand support is required, as this part is the right-hand item.
• Verify the part number 5139908 against the existing component or the appliance documentation.
• Inspect the casing panel itself for damage before refitting, as a distorted panel will not sit correctly on a new support.
