Absorption-type minibar fridge repair for luxury hotels — the ideal type for 5-star hotels because it is **completely silent** (no moving parts, zero decibels). It uses ammonia gas plus electric heat to drive a cooling cycle without a compressor. Cooling is weaker (8-10°C) but the elegance and silence are unmatched. Models: Dometic miniCool RH-431, Indel B K-Series. Call **16062**.
An absorption minibar works on the diffusion absorption refrigeration principle. There is no compressor; it has a heater element and hidden internal pipes filled with ammonia, water, and hydrogen. It must be perfectly level (a tilt over 3° permanently kills the system). Common faults: pipes blocked by sediment, a burned-out heater element, and tilt issues.
