Frequently Asked Questions

How do I know this is the right Lippert part?

Match the SKU 2020043670 to the label on your original component, the appliance data sticker, or the manufacturer parts diagram.

Can I choose this by appearance alone?

No. RV appliance, accessory, and system parts often look similar across model years, but controls, mounting points, finishes, and electrical specs can differ.

What should I pair with this part?

Most buyers pair it with their original screws, brackets, harnesses, or appliance housing unless the listing says new hardware is included. Replace worn filters, gaskets, or companion service parts at the same time only when your model calls for them.

What if my model number is different?

Use the comparison table and part number as a starting point, then verify before ordering. If the number does not match, use AI Live Chat with your model label so the correct option can be checked.
