Got a refrigerator question. We moved into an older house and there was a refrigerator there already. We brought ours and a deep freezer to the house. Have two refrigerators and a deep freeze all on the same circuit i think. The two fridges are turned to coldest settings but aren’t very cold. Is it possible I have too much on one circuit and that’s the reason?

Don't think so but if all compressors cycle on at the same time it may blow trip the breaker.

Also I would check that breaker now to make sure someone didn't put an over sized one in.

Old house wiring can be a problem.

Run large gauge extension cords to one of them and see. You may have low voltage.

Guess I could check voltage with a multimeter and see?

its recommended to have only one major appliance for each circuit (not just the plugs)

but its not uncommon to have 2 running on one line since its pretty uncommon for both to kick on at the same exact times

you absolutely dont want 3 on one line so move one of those to the garage or run a new separate wire for it to the breaker box.

all that said, as to your question, running on low voltage power supply due to overloaded line will cause wires to overheat and can lead to a compressor overheating but it should have no effect on its ability to cool as long as the compressor stays running. your compressors may be overheating and shutting down to cool off so yes there is a chance that low voltage issues are your problem. a simple way to test this is to run a good heavy duty (12 gauge) extension cord to another room you know is on a separate power circuit and hook one of the units to that and see what happens.
