Water leak caused by a bad splice in condensate tubing - redid condensate tubing splice and ran condensate pump several times to make sure leak had been addressed. Water seems to flow outside normally again. Rerouted steam humidifier drain into condensate pump.

Today, I addressed a 6-flash error code on a Muzfe09NA unit, indicating an outdoor thermistor fault. The outdoor unit had failed due to a mouse chewing on the outdoor ambient temperature thermistor. To restore operation temporarily, I spliced the thermistor. However, I recommend replacing the RT65 thermistor to prevent future issues. I will follow up with an estimate for replacing the outdoor ambient thermistor to ensure long-term reliability.
