This question involves a Frigidaire "affinity" electric dryer
with following identification numbers
In March of 2011 the above dryer failed to operate when activated so we contacted a local appliance repair company. They replaced the control unit, listed as part#134557200 on their invoice, and it again functioned in a normal manner. The technician commented that the control unit had been subjected to a power overload and asked if we had any electrical interruptions recently. Yes, we had.
The day before we were without any power for about 10-hours while Edison repaired some wires and poles damaged by a snow storm. I contacted Edison and while they acknowledged that they had been repairing the power lines just prior to the failure of the dryer, their letter states that "snow caused an overhead cross arm to break, and primary conductors to fail. This incident would have caused the high voltage you experienced, and was out of our control."
They denied any responsibility.
In November of 2011 we had a similar power outage for 8-hours, and upon reconnection, the same control unit failed and we had it replaced by the same local appliance repair company. The technician's diagnosis was the same as the first time. Edison's response was also the same.
My question is as follows:
Since the dryer was not in use at the time of the electrical "high voltage" that we experienced, could Edison's evaluation be accurate?
Since I have both failed control units is there someone somewhere who can evalute them and determine that they we in the "off" position when they failed?
What can be done to prevent this occurence in the future? Must we immediately disconnect the dryer whenever we experience a power outage, and wait for power to be retored before reconnecting?
Anxious for your reply
