RF transmitter interference to a GE electric stove
Most likely the electronics work off L1 or L2 only while stove works off L1&amp;2.  I might suggest MgZn ferrite snap-on choke on both L1&amp;L2 as they will couple anyways at 2MHz.  See if the video CM choke on any old VGA cable will fit around AWG10copper wires. These are molded in plastic sleeves but micro-gap but be perfectly matched and clean as an experiment, or large torroid on Coax feed to reduce CM radiation near power lines that converts to differential voltage from mismatch at controller due to power supply not having adequate CM filter.

So yes a line filter on AC, CM choke torroid over RF coax or both. You might be using fairly large core coax and large RF connectors , so snap-on types may be more easily applied.

MnZn has the largest Mu of 3k to 5k, suitable for CM choke in low RF in  low MHz region like the reducing VGA radiation on 75 Ohm Dsub cable.  THis ferrite is non-conductive, while the low mu NiZc ferrite suitable for microwave is conductive with test probe using a DMM, due to Nickel content and bigger ferrous gaps between particles.
