We have a 16000btu webasto fcf air conditioning. We use it nearly everyday at shore. This morning my wife went to turn it on and it powered up then immediately shut down and won't come back on. The remote and the panel both don't do anything. The breaker fuse never flipped but I went ahead and swapped it out anyway. Still nothing. Is there another fuse somewhere on this unit? All our other 120 fuses and accessories work fine so it's not the shore power either
