Basic Defrost Clocks, Defrost Issues And a 3 legged feral Raccoon Episode 418 Video May 05, 2025

Show notes

The podcast begins with a casual conversation about the unexpected costs of a supposedly 'free' phone screen replacement and a critique of USPS shipping woes. The hosts, Brett Wetzel and Kevin Compass, then share anecdotes from their recent experiences in Florida, including encounters with unique wildlife and travel frustrations. The conversation shifts to their primary topic—advanced techniques in refrigeration, particularly focusing on defrost systems. They discuss various defrost mechanisms such as mechanical and digital defrost clocks, hot gas defrost, and electric defrost systems, emphasizing proper troubleshooting methods and installation tips. Key points include the importance of accurate sensor placement, the impact of resistances on control circuits, and the pros and cons of different defrost methods. The hosts conclude with the promise (and jest) of a 'Part Two' to further expand on the complex topic.
