Anyone have a repair shop that will work on a Garmin transponder? I have a 327 and it has the button issues where if you press the numbers buttons, sometimes they work, sometimes they don't. More don't than do at this point. Otherwise it works fine. Anyone know of a shop that will just fix the issue? I don't want to spend $900 for a full work over when I don't need it. Thanks for any ideas. And by the way, how come we don't have a general avionics section? I see GPS, and COMM, but nothing for transponders.

I was very happy with Bevan’s rejuvenation of my trusty 430W.

Interim measure: sit in the cockpit on the ground with everything turned off, and repeatedly press the numbers buttons on the transponder. A lot. This can sometimes get them working, presumably it breaks through the oxidation (?).

If it does work, you could use candy etc. to bribe a small child to do this periodically, subject to local child labor laws of course. Kids seem to love to press buttons in airplanes. 🤣
 
As others have said, Bevan Avionics is the place. Good service, reasonably quick. Worth a call.

And I'll also second the recommendation to exercise the buttons. I've recovered multiple older pieces of Garmin equipment this way, usually after it's sat awhile. It takes a lot of button pushes. Remove the unit, take it home, put on a movie or a ball game, and start working the buttons.
 
Called Bevan today. They would only send it to Garmin. Have to find another option.

Remove the unit from the panel, only requires one 3/32 allen key.
Then remove the face plate - four phillips heads and then remove the display from the face plate.
Squirt contact cleaner around and in to the face plate in the opening where the display was (your are trying to get the contact cleaner between the layers as the face plate doesn't dissable any further), push buttons many times - do it again. Allow to dry out, 30 mins.
Reassemble and install - test.

And while it’s open, clean inside with compressed air, vacuum, shake upside down, etc. I had an old 430 that was doing weird things when buttons were pressed. I also pulled and reseated connectors I could easily get to. I think I got aluminum dust in the unit when doing panel work. That fixed it.
 
Heck, I'd just clean the button contacts. It's not a hard job at all. Qtip and some contact cleaner or alcohol.
