What causes compressor shell temperature too high protection in Friedrich FPHSW09A1B Air Conditioner?
- MMr. Drew KnappSep 14, 2025
If your Friedrich Air Conditioner is showing a 'Compressor shell temperature too high protection' error, it could be due to a loose compressor exhaust temperature sensor connector, in which case you should check it. Another possible cause is low refrigerant in the unit, in which case you should recharge the refrigerant.
