24v HVAC button removal

Post by stuart_in_oz » Sat Sep 29, 2018 1:05 pm

How do you remove buttons from the later (1993+) style HVAC console?

I want to swap a worn button with a good one from a spare unit but can't figure out how to remove the button without breaking something.

Has anyone else had a go at swapping buttons between HVAC computers?

Cheers,
Stuart.

You have to take the unit out, and disasseble the whole thing.

I have a spare unit for you (display not working) if you need it.

cheers

Cheers, I actually had the units apart to repair the LCD ribbon & wanted to swap a button between the two while I was in there.

Since you have taken it apart, I guess you have seen the tap at the bottom, but it is still connected at the top. I don't recall what I did to remove them, so not much help here, but I did have to disassemble the entire unit.
