Hi , I have a Frigidaire, double door, icemaker/water dispenser #FRS6HR45KSO...The unit started making a noise that resembled a fan, rubbing, while the icemaker and water dispenser was out of commission. Naturally, being male, I reset the machine, unplugged the various units to the "noisy area" behind the icemaker, and viola! All works....except the fan like noise which is intermittent, ever 45 min or so and is a bit loud. Any Clues??? Tks Weldon
