Our tech found a loose wire on the DC circuits on the mid AC that was causing the front AC to do the exact same thing as yours.

We replaced all caps on the front AC and we have a new thermostat that is not installed yet. Turned out to be a loose wire.

Let us know how it works out. Cheers.

Any way you could identify which wire? I would like to check mine. thanks!

Quick Update: Thanks for the reminder. I checked the connections where the front AC is daisy-chained into the middle AC. I tightened up the spade connectors on the +12, Gnd and SNGL wires. None seemed really loose but cleaning up the connections solved the problem. I had done this once before but the vibration from operation of the middle AC and driving must have recreated the problem. I'm going to add some cable ties to better support the connections.

Rvmaybe,

Great to hear.

I did not see which wires our tech worked on, but it must be the same ones.

Glad you got it fixed!
