The display on my wine cooler appears to dim and then brighten frequently.  Is there a problem?

Intermittent dimming and brightening of the display panel may be the result of a fluctuating power supply.  Oftentimes this is the case when the circuit board is no longer capable of  delivering consistent power to the various internal components of your appliance. A similar fluctuation may be noticeable with the circulation fan(s) as well.  Replacing the circuit board may be necessary.
