I have a problem with my 5 in 1 weather centre model 01536CAUDI/8900123 which I purchased in January this year. The external temperature is showing -40 deg and humidity is 1% - this happened suddenly with no issues prior to this. I've read all the previous issues like mine and completed all the various fixes as suggested by Acurite but cannot get the sensor to work correctly. I purchased the unit on Ebay Australia and cannot get any help with warranty information at all. Can anyone please assist with how I can get my system up and running again?
