I found some older posts with same problem, but mine is a little different than others: My Converter is a Progressive Dynamics Intellipower. All of a sudden last night we heard what sounds exactly like firecrackers or popcorn popping. At first we thought it was fireworks outside, but it was the Converter. I quickly turned off the 50 amp power at the post and the popping stopped. A visual inspection was negative, all looked normal. I plugged into 30 amp using my adapter and everything works fine - no popping. We went to bed and this A.M. the Camp owner checked the post and everything reads normal. Plugged into 50 amp and popping started... plugged into 30 amp, no popping; but - the 30 amp connection was loose due to a cracked 30 amp plug. He replaced the 30 amp plug and it works fine... Being the curious type, I plug back into the 50 amp and no popping. Been plugged back into 50 amp for an hour and all seems normal.... My questions: 1) What exactly is popping? arcing inside the converter? 2) why would it work on 30amp and popping on 50amp? 3) Does the 30 amp plug affect the 50amp operation and cause the popping? 4) Do I need to get a new converter? ................................ P.S. edit ..... I normally use a Surge Protector, but it went bad a couple weeks ago. I ordered a new Progressive unit, but won't be here until next week.
