Frequently Asked Questions

Q: How do I know if my cooling unit needs replacement?

A: Signs include: fridge not cooling on battery or shore power, frost buildup only on one side, or complete cooling failure. If your RM Series fridge ran fine for years and suddenly stopped cooling, the cooling unit is likely the culprit.

Q: Will this cooling unit work with my existing RM Series fridge cabinet?

A: Yes. This is a direct OEM replacement designed specifically for RM Series refrigerators. It installs into your existing cabinet without any modifications.

Q: Can I install this myself, or do I need a professional?

A: While some experienced RV owners handle the installation, we recommend professional installation to ensure proper sealing and optimal performance. Improper installation can compromise cooling efficiency.
