What to do if my Sanyo SAP-KRV123EH Air Conditioner malfunctions due to high-frequency noise?

  Elijah HarmonJul 29, 2025
  If your Sanyo Air Conditioner malfunctions due to abnormal signal pulses caused by high-frequency noise, especially if you are near broadcast stations with strong electromagnetic waves, amateur radio stations, electronic sewing machines, or arc-welding machines, insulate for noise or increase the distance from the noise source. You can also use shielded wires or move the unit away from the noise source.

Why does noise appear in the TV picture when using my Sanyo SAP-KRV123EH Air Conditioner?
- N
  Nicholas GarrettAug 11, 2025
  Noise in the television picture or static in the radio sound due to electromagnetic interference when using your Sanyo Air Conditioner can be caused by several factors: * A television or radio is located near the A/C and A/C wiring. In this case select a separate power source. * The antenna cable for a television or radio is located close to the A/C and A/C wiring. Keep the A/C and A/C wiring at least 1 meter away from wireless devices and antenna cables. * Locations where television and radio signals are weak. Use a noise filter for the wireless device. * Also change the wireless device’s antenna to a high-sensitivity antenna, the antenna cable to a BS coaxial cable or use a signal booster.
