Bell & Howell Ionic Whisper can't hear, even when put to ear. No slight air flow? Lights work? Was plugged in for awhile, mother passed. I unplugged and then wanted to use. Cleaned in side. It was even dirty? So, I'm not sure if it ever worked? Model no. 7842. Don't want to plug in again, just to light up green and red lights? I should feel a low air flow, I don't, zero motor noise even placed right to my ear. I have excellent hearing. Is it a bused or what??
