I looked at a peerless 4 fan evaporator this morning at my butchers shop. They had a power outage this morning and 3 of the 4 ecm evap motors burnt out. Can I replace these expensive little motors with standard wattage single pole motors? The ecm motors are expensive and don't appear to do anything other than move air in a single speed. I see no real advantage of these motors and they are 3 times as much as the standard shaded pole motors.
