Garbage disposals are a convenient kitchen tool—until they stop working. A jammed, humming, or completely silent unit can disrupt your daily routine and lead to plumbing problems if left unaddressed. In this Redfin article, we’ll walk you through the most common reasons your garbage disposal might not be working, how to troubleshoot it, and when it’s time to call a pro—whether you’re in a house in Chicago, IL or a home in Phoenix, AZ.
