Recalled Lennox Ductless Heat Pumps- MPA018S4M

Lennox Ductless Single-Zone and Multi-Zone heat pumps have been recalled because the units can overheat and catch on fire. 

Lennox has received two incident reports of units overheating, according to the U.S. Consumer Product Safety Commission. Both instances occurred in units installed in Canada. In one unit, failure of internal electrical components melted a hole in the heat pump motor. In the other, a fan blade and the motor caught on fire. No injuries were reported in either incident. 

The recall affects about 1,650 units sold in the United States, plus an additional 380 sold in Canada, between January 2016 and November 2019.The three recalled models of  Lennox Ductless Single-Zone or Multi-Zone heat pumps are MPA018S4M-1P, MPA048S4S-1P, and MPA048S4M-1P. Serial numbers can be found in recall notice 20-083

Free replacement of the outdoor unit can be arranged through a Lennox servicer, dealer, or contractor. While awaiting replacement, it is recommended facility managers keep an eye on the heat pumps and keep flammable items well away from the unit. 

Lennox can be reached at 800-527-3506 or at their website for more information.
