I'm in need of a control panel switch and knob for a specific electric dryer model, particularly the panda type that operates at 3.75. The components should meet the necessary quality standards and specifications to ensure compatibility and reliability. Could you provide details on pricing, availability, and lead times for these parts? Additionally, if you have any recommendations or alternative options that could work, I'd be keen to hear about those as well. Looking forward to your prompt response!
