Frequently Asked Questions

Q: How do I know if my refrigerator insulation needs replacement?
A: Signs include reduced cooling capacity, temperature fluctuations, visible cracks or compression in foam, or increased power draw. If your fridge isn't holding temperature like it used to, foam degradation is often the culprit.

Q: Will these foam blocks work on other Dometic refrigerator models?
A: These blocks are specifically designed for SP and FJX5 series models. Always verify your refrigerator model before ordering to ensure proper fit.

Q: Is professional installation required?
A: Most RV owners can install these blocks themselves with basic tools. However, if you're uncomfortable accessing internal refrigerator components, we recommend consulting a qualified RV technician.
