WF-8955-PEC 30 converter in my 2015 Rpod 180 that after only 1 year,  is no longer working.  Read about how these unit fail fairly regularly.  I just got back from a 4000 km trip to the Yukon and did some gravel road towing and that may have been the cause (vibration).  My batteries are good, (pair of 6 volt only 8 months old and I never let them get below 12.4 volts.  

Thanks furpod for the link and directing me to the correct model.  I can get one on Amazon.ca with prime, CAD $330.

I just replaced my WFCO converter with the progressive dynamics 4655. It is a direct replacement and can be done by you. The company warns about internet purchases some that do not come with a serial number. I purchased mine from best converter RV electrical supplies and it was legitimate. Unfortunately my first unit made an unusual noise but progressive was aware of the problem and immediately replaced it with no questions or paperwork. A good American company who stands by their product. Took about 1 hour the first time and 15 minutes the second time for installation. It works great.

Originally posted by lostagain shark, you may want to contact WFCO about a warranty replacement.  Seems to me their warranty is 2 years, if I recall correctly.  Then you can keep it as a spare after buying the new Progressive Dynamics converter.  Since I recently replaced my WFCO with a new one (still working just fine) this is what I plan to do if there is a failure during the warranty time. Also, one member suggested putting a little foam cushioning below the converter to dampen the vibrations.  I tried it with a piece of thin carpet pad and all is working nicely.
