What causes the F91 Refrigeration Cycle Abnormality in Panasonic CS-MRE7MKE Other, and how to fix it?
- KKatherine TaylorAug 23, 2025
The F91 error in your Panasonic Other indicates a refrigeration cycle abnormality. This can be caused by several factors: * Faulty indoor intake air or pipe temperature sensors, which should be replaced. * A closed 2/3 way valve, requiring inspection and opening. * Refrigerant shortage due to leaks, necessitating a check for leaks and replenishment. * A clogged expansion valve or strainer, which should be cleaned or replaced. * A faulty outdoor unit, so consider replacing it. * Poor compressor compression, requiring a check, repair, or replacement of the compressor.
