Refrigerated display cases can last for many years when properly maintained. Yet, there are signs that signify a unit needs to be replaced.
The signs that a display case has reached the end of its service life can be obvious or subtle. Here's what to look for.
Excessive Noise: If there are sounds or rattling coming from the compressor, or if the motor is running very loudly, it may be time to consider purchasing a new unit.
Temperature Inconsistencies: If there are inside temperature fluctuations, or excessive condensation on the door interiors, the unit could be failing and replacement should be contemplated.
