      Zack, I've att. the service manual for your unit.
      It will help you troubleshoot your problem.

The fastest way to mess up a tube is to stuff a dish rag or oversized brush into it when trying to clean it. It forces the seam apart and ruins it.

It's probably a good idea to remove the nameplate and retaining plate and clean out the residue to avoid corrosion issues in the future. If the unit is switching from HIGH to LOW, nothing is sticking.
