Dometic a/c error

[dragon56]

Hi has anyone had this problem….the roof mounted dometic air con unit in my motor home doesn’t work. The fan works fine but there is an E2 error on the control panel.
I have been trying to find someone to take a look at it but no luck so far.

Have you googled it?

It says "out of range Heat sensor" when I just did.
