I've been experiencing issues with my towel warmer, which, despite being relatively new (just over a year and a half), doesn't seem to operate properly. It frequently turns on and off, failing to maintain a consistent temperature. In the past, I've owned other towel warmers that lasted much longer without any problems. I'd really appreciate some help in troubleshooting this issue. Is there a specific process I should follow, or any common solutions you might recommend? It would be great to resolve this so I can enjoy using the warmer as intended. Thanks for your assistance!
