A/C transformer ?

This is above my sink in my 65 Safari, and the switch is the On / Off for the A/C. Can anyone tell me why it has a transformer attached ? And if I should keep it when I install the new Unit ? Thanks Much !

just guessing

hmm, interesting; one of the trouble spots on an rv is not having robust 120VAC to start up the airconditioning. A low voltage can cause slow startup and actually do damage to the air conditioner. so, perhaps the PO put in a small step up transformer to increase the AC by say, 10%? just a guess; ie: nominal 120VAC in, nominal 132VAC out; if the trailer is getting 108VAC, then it would increase it to 118VAC. What wires are connected, and how they are connected will tell ya what the thing is doing. If it is part of the air conditioning circuit, then it'll be in series with the Air conditioning wiring. If it does something else, there will be more than just the wires to the airconditioning.

If there's a transformer in there it looks like the size used to operate a doorbell, not an A/C... My guess is it is a filter choke used to reduce squiggly lines the PO may have seen on his TV when the A/C was running.

That is probably to power the thermostat. They run on 24VAC.
