美国采购需求：毛巾加热器、毛巾杆加热器、艺术散热器、毛巾散热器、P&Bhusri 毛巾加热器、毛巾杆加热器

I recently purchased a heated towel rack, but I've noticed it's not heating up to the temperatures I expected. It warms up a bit, but my towels don't get that cozy, toasty warmth anymore. I'm wondering if there might be a reset option or some troubleshooting steps I can take to get it back to its optimal performance. Would you be able to provide any guidance on resolving this issue? It's essential for me to have it working efficiently again, as I rely on it for my daily routines. Thank you for your assistance!
