Sadly the best solution is to get your 1050 and fridge on separate circuits - not the easiest solution, but a pretty sure-fire one generally (assuming the overall house service isn't pretty severely undersized, which it shouldn't be). Excluding that, a power conditioner might help smooth things out when the compressor inrush hits, but I'm not sure if it would be a completely successful solution. I felt like I had pretty decent luck with weeding out noise from the fridge at my old house when I added a Panamax MAX5100 before I got a separate circuit run to the equipment rack, but it's been a few years and I only had the Panamax in place for a couple of weeks before the dedicated circuit went in.
