  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 Air Conditioner?
- S
  Suzanne EverettAug 16, 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.

What causes the motor to stop quickly when the outdoor unit operates in my Sanyo SAP-CRV123EHN?
- T
  toddderrickAug 26, 2025
  If the motor rotates for a few seconds and then quickly stops when the outdoor unit operates in your Sanyo Air Conditioner, there is trouble in the system that provides feedback of motor rotation speed from the motor to the outdoor unit controller.

What does it mean if the operation lamp blinks every 0.5 seconds on my Sanyo Air Conditioner?
- K
  Kathleen NormanAug 29, 2025
  If the operation lamp blinks every 0.5 seconds immediately when the power is turned ON, it indicates an external ROM (OTP data) failure on the indoor circuit board, a ROM socket insertion problem, or that the ROM has not been installed.
