Sorry to hear you’re having issues with your equipment.
It all depends on what might be wrong. When mine went bad, I asked the boys at Gander and they gave me a couple options: 1. Buy a new one. 2. Send it it to the manufacturer (which, after reviewing costs of doing so with the company, it made more sense to replace it.) So, unless you have a unit over, say $300, probably best bet is to just replace it. Again, however, it depends on what is wrong with it.
Good luck.
