Comfee MPD1-12CRN7 recall: compressor power cable insulation wears against copper pipe, sparking can ignite refrigerant and unit
The recall covers the portable MPD1-12CRN7 (EAN 4048164102914, 2019 production) and the identical Midea Mobile 35C. The compressor power cable can rub against the copper refrigerant pipe; with prolonged/intense use the insulation wears, causing electrical sparking that can ignite the R290 refrigerant and the unit itself. The manufacturer asks owners to stop using the unit immediately and contact their dealer. This is a high-severity fire hazard from an electrical defect.
What to check. If you own a 2019 Comfee MPD1-12CRN7, stop using it immediately and contact the dealer/Midea Europe service (free line +49 6196 90 20 290, [email protected]) to arrange the recall remedy. Do not continue running the unit while waiting.
IFS-documented fire in a 2019 Comfee portable AC: short circuit between compressor power connection and coolant line melted the line, flammable refrigerant leaked and ignited
Safety risk
IFS investigated a real fire in a server room where a 2019 Comfee 'Eco Friendly' portable AC ran about two hours before smoke was noticed; the fire was extinguished before spreading. Laboratory examination found a short circuit between the compressor power connection and a coolant line, which melted the line so the flammable refrigerant leaked and ignited. IFS notes this matches the failure pattern of the MPD1-12CRN7 recall, though the specific unit examined was not itself on the recall list. This independently corroborates the manufacturer's recall warning with an actual ignition event.
What to check. Treat the fire risk as real, not hypothetical: an independent laboratory documented an actual ignition from this exact failure mode in a 2019 Comfee portable unit. Verify your unit's serial number against the recall and stop using it until resolved.
Comfee MPD1-12CRN7 cooling output reportedly falls short of rating (~10 kBtu/h instead of 12,000 BTU)
A buyer cites an Amazon review claiming the MPD1-12CRN7 does not even reach 10 kBtu/h of cooling from its rated power draw (the unit is rated 12,000 BTU / 3.5 kW). This is a single second-hand owner report, not a measured test, so it is low severity, but it suggests real-world cooling output may fall short of the rating for a 31 m² room.
What to check. If you are sizing this unit for a room near its rated capacity (about 41 m²), expect that real cooling output may be lower than the 12,000 BTU rating; consider oversizing or a two-hose unit for a large space.
