Frequently Asked Questions

How do I know if my cooling unit has failed?

Common signs include: refrigerator not cooling in any mode (gas, electric, or auto), yellow powder or staining on the cooling unit, strong ammonia smell, or visible corrosion on the cooling coils. If your refrigerator worked fine and suddenly stopped cooling completely, the cooling unit is the most likely culprit.

Can I install this cooling unit myself?

Installation requires removing the refrigerator from the RV cabinet, disconnecting gas and electrical connections, and replacing the entire cooling unit assembly. While mechanically inclined RV owners can perform this repair, it involves propane system work and precise mounting. Many owners choose professional installation to ensure proper gas connections and system safety.

Will this work with my BX refrigerator if it runs on propane and 120V AC?

Yes, this cooling unit is designed for BX Series refrigerators that operate on multiple power sources. The cooling unit itself is the same regardless of power mode—the control system and heating elements determine which energy source is used. This unit works with all BX Series power configurations.

How long does a Dometic cooling unit typically last?

Dometic absorption cooling units typically last 15-20 years with proper maintenance and level operation. Factors that shorten lifespan include prolonged operation while not level, overheating due to blocked ventilation, and manufacturing defects. Replacing a failed cooling unit is often more cost-effective than replacing the entire refrigerator.
