Tune in here for this 3-21-26 episode of the Home Depot Home Improvement show on WBT with John Gordon and David Dovell.

On this edition of the program, John and Dave talk about common home maintenance issues and practical troubleshooting tips for everyday homeowners. They kick things off with a discussion about an oven that isn’t holding temperature, walking through possible causes like a faulty thermostat or a burned-out heating element, and explaining how an ohm meter can help diagnose the problem. The conversation then shifts into the realities of modern DIY work, with John sharing his frustrations—and small victories—while installing crown molding and adjusting to new digital tools. 

They also break down a listener question about a mysterious “mini tank” above a water heater, clarifying that it’s an expansion tank designed to manage pressure changes in today’s plumbing systems. Throughout the show, their easy back-and-forth blends humor, experience, and straightforward advice for tackling projects at home.
