Ultra Aire 155 dehumidifier perhaps dying (again)

Hi,

I hate to have to post this... but once a year my Thermastor Ultra Aire 155xt dies and needs to be replaced. I am on my 3rd unit in as many years and I am concerned this one is starting to fail.

All summer it has been operating very consistently with output temps around 90 and dew points about 5 degrees lower than the intake air.

Today it started operating inconsistently with very high output temps being recorded (as high as 111 degrees F). Please see recent temperature / dew point charts attached. The input air has been slightly drier in the past but basically fairly consistent.

I have turned the unit off for now but would like some idea from anyone what might be going on. I have attached 2 images/charts... one for the last 24 hours and another for the last 7 days.

Any help is appreciated.

Thanks... George
