My 5-in-1 is either model 06004R or 06004RM (I don't feel like climbing on the roof again). My display is model 01036-RX. It is stuck reporting 99% outdoor humidity. About 45 days ago I replaced the single cell fan with a PRO+ upgrade (model 06003M or 06003RM). I have done the hard reset a couple of times now with no luck. I have fresh alkaline batteries. I have changed the channel a couple of times now. I heard there may be a part that can be replaced? I'm sure that everything is out of warranty (this is now my second 5-in-1, my second indoor display, my original Smart HUB <which got the big firmware upgrade a couple of years back>, my second Wind Cup Assembly <although now I've got the Pro+>, and I just added two wireless Temperature/Humidity Sensors (for a gun safe and a storage area). Please help!
