A Perlick 63789 Defrost Timer keeps defrost cycles operating at the proper cadence, so the unit's cooling system is running appropriately.
The Perlick 63789 Defrost Timer coordinates defrost timing within the refrigeration system. Its role within the system helps support proper defrosting and effective refrigeration operation.
The Perlick 63789 Defrost Timer may be nearing the end of its useful life if the unit stops cooling, needs to be unplugged to defrost or develops ice buildup or water pooling. Performance-related signs can include a compressor that does not start, inaccurate defrost timing or a unit that fails to defrost properly, which might be improved by using a real OEM replacement for greater durability.
