This True 831972 defrost timer is a perfect replacement for the one that came standard on select glass frosters. If your unit's defrost cycle is not operating properly, a bad timer could be the issue, and you will want to correct the problem promptly since harmful ice buildup can hamper energy efficiency.

This part replaces items 831921 and 831918.

Due to manufacturer production variations, check the Compatibility resource to ensure this part is suitable for your application.
