Topic: Broken weather station

[KOJIbT]

Hi everyone. I have a froggitt wh3000se weather transmitter and station. Had it for 4 years. Its linked to my ecowett account.
Sadly parts of the transmitter is starting to fail the temperature gauge is breaking down intermittently.
Firstly does anyone know I'd I can replace the temperature sensor.
Secondly if I just brought a new transmitter (actual weather station) would that link to existing reciever if it was on the same frequency?
