Why is my Pioneer PYR009AZFRVBKE Air Conditioner not cooling?
- RRichard RamirezAug 6, 2025
If your Pioneer Air Conditioner isn't cooling, several factors could be at play. It might be that the current temperature is lower than 64°F or the set point temperature has already been reached. Other potential causes include a defective thermistor or thermal protection, low refrigerant levels, a damaged compressor, dirty heat exchanger coils, a defective external fan, or the MODE button not being correctly set.
