Bought an indoor electric grill from Walmart, about $15. Worked great, perfect for my needs, certainly cheap enough. Now the problem: It has a thermometer control built into the electric line that plugs into the grill with a probe. In time the probe has developed a sloppy fit, electrically, and the grill shuts off. I can wiggle the probe and find a "hot spot" where it works and use something to prop it in place. Is there anything I can do to tighten up the probe fit and keep the electrons flowing?
